Preface
ABOUT AUTOMATED EXTERNAL DEFIBRILLATION
The following considerations and guidelines apply when using the LIFEPAK® 20e defibrillator/
monitor as an automated external defibrillator (AED).
Operator Considerations
The LIFEPAK 20e defibrillator/monitor, when in AED mode, is a semiautomatic defibrillator that
uses a patented Shock Advisory System™. This software algorithm analyzes the patient’s
electrocardiographic (ECG) rhythm and indicates whether or not it detects a shockable rhythm.
The LIFEPAK 20e defibrillator/monitor in AED mode requires operator interaction to defibrillate
the patient.
The LIFEPAK 20e defibrillator/monitor in AED mode is intended for use by personnel who are
authorized by a physician/medical director and have, at a minimum, the following skills and
training:
• CPR training.
• AED training equivalent to that recommended by the American Heart Association.
• Training in the use of the LIFEPAK 20e defibrillator/monitor in AED mode.
Indications
The AED mode is to be used only on patients in cardiopulmonary arrest. The patient must be
unconscious, pulseless, and not breathing normally before using the defibrillator to analyze the
patient’s ECG rhythm.
In AED mode, the LIFEPAK 20e defibrillator/monitor is not intended for use on pediatric patients
less than 8 years old.
Contraindications
None known.

LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Preface
Preface
ABOUT DEFIBRILLATION THERAPY
Operator Considerations
A direct current defibrillator applies a brief, intense pulse of electricity to the heart muscle. The
LIFEPAK 20e defibrillator/monitor delivers this energy through disposable electrodes, standard
paddles or internal paddles applied to the patient’s chest.
Defibrillation is only one aspect of the medical care required to resuscitate a patient with a
shockable ECG rhythm. Depending on the situation, other supportive measures may include:
• Cardiopulmonary resuscitation (CPR)
• Administration of supplemental oxygen
• Drug therapy
Successful resuscitation is related to the length of time between the onset of a heart rhythm that
does not circulate blood (ventricular fibrillation, pulseless ventricular tachycardia) and
defibrillation. The American Heart Association has identified the following as critical links in the
chain of survival from cardiac arrest:
• Early access
• Early CPR by first responders or bystanders
• Early defibrillation
• Early advanced life support
The physiological state of the patient may affect the likelihood of successful defibrillation. Thus,
failure to resuscitate a patient is not a reliable indicator of defibrillator performance. Patients will
often exhibit a muscular response (such as jumping or twitching) during an energy transfer. The
absence of such a response is not a reliable indicator of actual energy delivery or device
performance.
Indications
Defibrillation is a recognized means of terminating certain potentially fatal arrhythmias, such as
ventricular fibrillation and symptomatic ventricular tachycardia. Delivery of this energy in the
synchronized mode is a method for treating atrial fibrillation, atrial flutter, paroxysmal
supraventricular tachycardia and, in relatively stable patients, ventricular tachycardia.
Contraindications
Defibrillation is contraindicated in the treatment of Pulseless Electrical Activity (PEA) such as
idioventricular or ventricular escape rhythms, and in the treatment of asystole.

Preface
ABOUT NONINVASIVE PACING
A noninvasive pacemaker is a device that delivers an electrical stimulus to the heart, causing
cardiac depolarization and myocardial contraction. The energy is delivered through large
adhesive electrodes placed on the chest. In addition to noninvasive pacing, other supportive
measures may be necessary.
Among other factors, it is recognized that successful pacing of a patient is related to the length of
time between the onset of a dysrhythmia and the initiation of pacing. Rapid pacing and prompt
follow-up care are essential. The physiologic state of the patient may affect the likelihood of
successful pacing or of skeletal muscle activity. The failure to successfully pace a patient is not a
reliable indicator of pacemaker performance. Similarly, the patient’s muscular response to pacing
is not a reliable indicator of energy delivered. Refer to the booklet, Noninvasive Pacing: What You
Should Know for further information.
Indications
Noninvasive pacing is indicated for symptomatic bradycardia in patients with a pulse.
Contraindications
Noninvasive pacing is contraindicated for the treatment of ventricular fibrillation and asystole.
ABOUT SPO2 MONITORING
A pulse oximeter is a noninvasive device that checks the saturation of oxygen in arterial blood
(SpO2). It uses an optical sensor that directs light through the patient’s finger and then measures
the received light with a detector. This received light is translated into a saturation percentage
and is displayed as an SpO2 reading.
Indications
A pulse oximeter is indicated for use in any patient who is at risk of developing hypoxemia.
Contraindications
None known.
ABOUT ECG MONITORING
The ECG (electrocardiogram) is a recording of the electrical activity of the heart. ECG monitoring
allows for identification and interpretation of cardiac rhythms or dysrhythmias and calculation of
heart rate. The ECG is obtained by placing either electrodes or paddles on the patient and allows
the heart’s electrical activity to be monitored and recorded.

Preface
Preface
ABOUT ETCO2 MONITORING
The end-tidal carbon dioxide (EtCO2) monitor is a capnograph device that uses non-dispersive
infrared spectroscopy to continuously measure the amount of CO2 during each breath and report
the amount present at the end of exhalation (EtCO2). The sample is obtained by the side stream
method and can be used with intubated or nonintubated patients. Respiration rate is also
measured and displayed in breaths per minute.
The EtCO2 monitor is a tool to be used in addition to patient assessment. Care should be taken
to assess the patient at all times; do not rely solely on the EtCO2 monitor.
Indications
EtCO2 monitoring is used to detect the level of expired CO2. It is used for monitoring breathing
efficacy and treatment effectiveness in acute cardiopulmonary care, for example, to determine if
adequate compressions are being performed during CPR or to rapidly detect whether an
endotracheal tube has been placed successfully.
Contraindications
None known.

Monitoring Area—Heart Rate
WARNING!
Failure to detect a change in ECG rhythm.
Heart rate meters may continue to count the internal pacing pulses during occurrences of
cardiac arrest or some arrhythmias. Do not rely entirely on heart rate meter alarms. Keep
pacemaker patients under close surveillance.
QRS detection is essential for using the digital heart rate display, systole tone, synchronized
cardioversion, and noninvasive demand pacing. The QRS detector in the LIFEPAK 20e
defibrillator/monitor selectively detects QRS complexes. It discriminates against most noise,
muscle artifact, T-waves, and other spurious signals.
The QRS detect algorithm automatically adjusts itself to the amplitude of the QRS complexes.
Changing the gain of the ECG has no effect on QRS detection. For optimum QRS detection
performance, use the lead with the greatest QRS amplitude.

CONNECTING TO POWER
The LIFEPAK 20e defibrillator/monitor and the optional CodeManagement Module operate on
AC (line) power or their internal Lithium-ion batteries. You can switch from battery to AC power or
AC power to battery while the device is on and in use by plugging in or unplugging the AC power
cord.
When the CodeManagement Module is connected to the LIFEPAK 20e defibrillator, one power
cord is used to power both the defibrillator and the CodeManagement Module.
IMPORTANT: The AC power cord is the safety disconnect mechanism. Maintain clear access
to all connections at all times.
WARNING!
Possible defibrillator shutdown.
When operating on battery power, adhere to battery maintenance and replacement intervals
discussed in the Battery Performance and Life section to prevent possible defibrillator shutdown.
If the defibrillator shuts down without warning, or if a LOW BATTERY: CONNECT TO AC
POWER message appears on the monitor screen, immediately connect the AC power cord to an
outlet.
AC Operation
When the LIFEPAK 20e defibrillator/monitor operates on AC power, the AC Mains LED
illuminates. When the defibrillator is not in use, the battery charge is best maintained if the power
cord is connected to an AC outlet and the defibrillator is turned off.
Note: When the CodeManagement Module is attached to the defibrillator, the green LED on
the CodeManagement Module and the AC Mains LED on the defibrillator are both illuminated
while the device is connected to AC power.
BATTERY OPERATION
The LIFEPAK 20e defibrillator/monitor and the CodeManagement Module each have an internal
battery. Battery operation for the defibrillator is explained below. Battery operation for the
CodeManagement Module is explained on page 2-23.
LIFEPAK 20e Defibrillator/Monitor Battery
The internal Lithium-ion battery is rechargeable and is intended for use when AC power is
unavailable or when the device is being used in a portable manner, such as in transport. The
defibrillator automatically switches to battery power when the power cord is disconnected from
an AC outlet or from the defibrillator.
2-20
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Basic Orientation
A new, fully charged battery provides approximately 140 360-joule discharges, 110 minutes of
pacing, or approximately 210 minutes of continuous monitoring before the defibrillator turns off.
When one flashing red bar appears in the battery status indicator and the LOW BATTERY:
CONNECT TO AC POWER message appears on the screen, immediately plug the power cord into
an AC outlet to continue use and begin recharging the battery. If low battery messages
frequently appear, the battery may need to be replaced. Contact Physio-Control Technical
Support or qualified service personnel for assistance.
Connect the defibrillator to AC power after each use to recharge the battery. Typically, new fully
depleted batteries recharge for 4 hours to regain full capacity. Partially depleted batteries
recharge for a time period equivalent to the time the defibrillator was in use. For example, if the
defibrillator was used one hour, the required recharge time will be approximately one hour.
New batteries or batteries that have been stored for an extended time should be recharged
before they are used. Connect the defibrillator to an AC power outlet to bring the battery to full
charge.
Note: The LIFEPAK 20e defibrillator/monitor is intended to operate with the internal battery
installed. In the event of a missing or faulty battery, when plugged into AC power, the device
will still operate and the service light will illuminate at power on. Contact Physio-Control
Technical Support or qualified service personnel for assistance.
Battery Performance and Life
Several factors can contribute to the Lithium-ion battery’s performance and life cycle, including:
1 The defibrillator’s use for assisting patients (“on time” and shocks).
2 The defibrillator’s use when the battery is at minimum capacity (low battery condition).
3 The battery’s normal self-discharge rate and the energy used by defibrillator self-tests.
To maximize battery performance and life, plug the defibrillator/monitor into an AC outlet to
recharge the battery whenever the defibrillator/monitor is not in use. As a reminder, you can set
up the LIFEPAK 20e defibrillator/monitor to sound a series of warning beeps, identified as AC
LOSS ALERT, whenever the defibrillator is turned off and not plugged into an AC outlet (refer to
the "General Setup Menu," page 8-4).
Note: Even when properly maintained, the internal rechargeable Lithium-ion battery should
be replaced every two years.
Battery Status Indicator
The battery status indicator approximates the amount of operating time available under battery
power for the LIFEPAK 20e defibrillator/monitor. It does not indicate battery status for the
CodeManagement Module. The battery status indicator appears on the screen after the
defibrillator is turned on. (See Figure 2-13, page 2-10.) The number of illuminated bars indicates
the battery capacity and how long the battery will provide power to the defibrillator.
A new, fully charged battery will show four green bars, indicating the battery is charged to 100%
capacity. As battery charge and battery capacity decreases, the indicator bars decrease
incrementally. One flashing red bar indicates a very low or empty battery. Refer to Table 2-2.

Message remains in message area,
cycling with others if necessary.
It is important to note that both charge (voltage) and capacity are factors contributing to the
battery status indicator’s display. For example, the battery status indicator displays two green
bars when a new battery has 100% capacity and has been charged to 50%. However, an
older battery that is 100% charged and only has 50% capacity also displays two green bars.
The following demonstrates this example.
This battery may either be low in capacity or low in charge as follows:
• For a new battery with 100% capacity, this symbol indicates 50% charged (low in
charge).
• For an older battery with 50% capacity, this symbol indicates 100% charged (low
in capacity).

CodeManagement Module Battery
The CodeManagement Module has an internal, rechargeable Lithium-ion battery. When the
CodeManagement Module is properly connected to the LIFEPAK 20e defibrillator and AC power,
the batteries in the defibrillator and CodeManagement Module both recharge. When the device is
disconnected from AC power, both the defibrillator and CodeManagement Module automatically
switch to battery power.
To ensure the CodeManagement Module is always ready for use, keep it plugged into an AC
outlet whenever possible.
WARNING!
Possible CO2 monitoring shutdown.
When operating on battery power, adhere to recommended battery charging and replacement
intervals to prevent possible CO2 monitoring shutdown. If a CONNECT TO AC POWER
message appears on the monitor screen, immediately connect the AC power cord to an outlet.
Notes:
• One power cord is used to power both the defibrillator and the CodeManagement Module.
• If the battery in the CodeManagement Module is low and the LIFEPAK 20e defibrillator is on,
the CONNECT TO AC POWER message appears, and three beeps sound every 20 seconds.
A new, fully-charged battery for the CodeManagement Module provides 270 minutes of
continuous CO2 monitoring. Typically, a new, fully depleted battery recharges for 4 hours to
regain full capacity. The battery should be replaced every two years. Battery replacement must
be performed by qualified service personnel.

to the sternum and below the clavicle as shown in Figure 3-1.
Special Placement Situations
When placing therapy electrodes or standard paddles, be aware of the special requirements in
the following possible situations.
• Obese Patients or Patients with Large Breasts — Apply therapy electrodes or standard
paddles to a flat area on the chest, if possible. If skin folds or breast tissue prevent good
adhesion, it may be necessary to spread skin folds apart to create a flat surface.
• Thin Patients — Follow the contour of the ribs and spaces when pressing the therapy
electrodes or standard paddles onto the torso. This limits air spaces or gaps under the
electrodes and promotes good skin contact.
• Patients with Implanted Pacemakers — If possible, place therapy electrodes or standard
paddles away from internal pacemaker generator.
• Patients with Implanted Defibrillators — Apply therapy electrodes or standard paddles in
the anterior-lateral position and treat this patient as any other patient requiring emergency
care.
Paddles Monitoring Procedure
To monitor using therapy electrodes or standard paddles:
1 Press ON.
2 Prepare the patient’s skin:
• Remove excessive chest hair as much as possible. Avoid nicking or cutting the skin. If
possible, avoid placing therapy electrodes or standard paddles over broken skin.
• Clean and dry the skin.
• Do not use alcohol, tincture of benzoin, or antiperspirant to prep the skin.

ECG Electrode Requirements
Electrode quality is critical for obtaining an undistorted ECG signal. Always check the date code
on electrode packages for the Use By date before applying the electrodes to a patient. Do not use
electrodes with expired Use By date codes. Disposable electrodes are intended for a single use.
For best ECG monitoring results, use silver/silver chloride (Ag/AgCl) electrodes. These
electrodes provide a rapid display of post-defibrillation ECG.
Leads Off Messages
If an electrode or lead wire disconnects during ECG monitoring, the monitor emits an audible
alarm and displays a leads off message. The ECG trace becomes a dashed line. The alarm and
messages continue until the electrode or lead wire is replaced.
Color Coding for ECG Leads
The lead wires and the electrode snaps for the patient ECG cable are color coded according to
AHA or IEC standards as listed in Table 3-1.

Monitoring Patients with Internal Pacemakers
The LIFEPAK 20e defibrillator/monitor typically does not use internal pacemaker pulses to
calculate the heart rate. However, the monitor may detect internal pacemaker pulses as QRS
complexes. This may result in an inaccurate heart rate display.
Smaller amplitude internal pacemaker pulses may not be distinguished clearly. For improved
detection and display of internal pacemaker pulses, turn on the internal pacemaker detector, and/
or connect the ECG cable, select an ECG lead, and print the ECG in diagnostic frequency
response.
Large amplitude pacemaker pulses may overload the QRS complex detector circuitry so that no
paced QRS complexes are counted. To help minimize ECG pickup of large unipolar pacemaker
pulses when monitoring patients with internal pacemakers, place ECG electrodes so the line
3-6
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Monitoring
The LIFEPAK 20e defibrillator/monitor annotates internal pacemaker pulses with a hollow arrow
on the display and the printed ECG if this feature is configured or selected ON. False
annotations of this arrow may occur if ECG artifacts mimic internal pacer pulses. If false
annotations occur, you may deactivate the detection feature using the Options/Pacing/Internal
Pacer menu (refer to Figure 2-7). Also refer to the "Pacing Setup Menu" in Table 8-9. Patient
history and other ECG waveform data, such as wide QRS complexes, should be used to verify
the presence of an internal pacemaker.
Troubleshooting Tips for ECG Monitoring
If problems occur while monitoring the ECG, check the list of observations in Table 3-2 for aid in
troubleshooting. For basic troubleshooting problems such as no power, refer to "General

Shock or burn hazard.
Other manufacturers’ oxygen transducers may cause improper oximeter performance and
invalidate safety agency certification. Use only oxygen transducers approved for this product.
Inaccurate pulse oximeter readings.
Do not use a damaged extension cable or one with exposed electrical contacts. Never use more
than one extension cable between the pulse oximeter and the sensor.
Inaccurate pulse oximeter readings.
Do not use a damaged sensor. Do not alter the sensor in any way. Alterations or modifications
may affect performance and/or accuracy.
Inaccurate pulse oximeter readings.
Sensors exposed to ambient light (such as sunlight, surgical lights, or bilirubin lamp) when
incorrectly applied to a patient may exhibit inaccurate saturation readings. Securely place the
sensor on the patient and check the sensor’s application frequently to help ensure accurate
readings.

Monitoring
WARNINGS! (CONTINUED)
Inaccurate pulse oximeter readings.
Severe anemia, significant blood levels of carboxyhemoglobin or methemoglobin, elevated
levels of total bilirubin, intravascular dyes that change usual blood pigmentation, excessive
patient movement, venous pulsations, electrosurgical interference, exposure to irradiation and
placement of the sensor on an extremity that has a blood pressure cuff, intravascular line or
externally applied coloring (such as nail polish) may interfere with oximeter performance. The
operator should be thoroughly familiar with the operation of the oximeter prior to use.
Inaccurate pulse oximeter readings.
The pulsations from intra-aortic balloon support can be additive to the pulse rate. Verify patient’s
pulse rate against the ECG heart rate.
Skin injury.
Prolonged, continuous use of a sensor may cause irritation, blistering, or pressure necrosis of
the skin. Check the sensor site regularly based on patient condition and type of sensor. Change
the sensor site if skin changes occur. Do not use tape to hold the sensor in place, as this may
cause inaccurate readings or damage to the sensor or skin.
Possible strangulation.
Carefully route patient cabling to reduce the possibility of patient entanglement or strangulation.
CAUTION!
Possible equipment damage.
To avoid damaging the extension cable or the sensor, hold the connectors, rather than the
cables, when disconnecting.
When to Use a Pulse Oximeter
A pulse oximeter is a noninvasive tool that checks the saturation of oxygen in arterial blood
(SpO2) and is not to be used as an apnea monitor or as a replacement or substitute for ECG
based arrhythmia analysis. It is used for monitoring patients who are at risk of developing
hypoxemia. If a pulse oximeter is not used, the only indications of hypoxemia are a patient’s
dusky skin, nail beds, and mucous membranes, accompanied by restlessness and confusion.
These indications are not conclusive, however, and do not appear until after the patient has
developed hypoxemia. Pulse oximetry is to be used in addition to patient assessment. Care
should be taken to assess the patient at all times and to not solely rely on the SpO2 reading. If a
trend toward patient deoxygenation is indicated, blood samples should be analyzed using
laboratory instruments to completely understand the patient’s condition.
How a Pulse Oximeter Works
A pulse oximeter sensor directs light through a fleshy body site (usually the finger or earlobe).
The sensor sends light from the emitting diodes to the receiving detector as shown in Figure 3-4.
Oxygen saturated blood absorbs light differently as compared to unsaturated blood. The pulse
oximeter translates the amount of light received into a saturation percentage and displays an
SpO2 reading. Normal values typically range from 95% to 100% at sea level.

Figure 3-4 How a Pulse Oximeter Works
The quality of the SpO2 reading depends on correct sensor size and placement, adequate blood
flow through the sensor site, patient motion, and exposure to ambient light. For example, with
very low perfusion at the monitored site, readings may read lower than core arterial oxygen
saturation. Test methods for accuracy are available by contacting your local Physio-Control
representative.
SpO2 Monitoring Considerations
Each oximeter sensor is applied to a specific site on the patient. Use the following criteria to
select the appropriate sensor:
• Patient weight
• Patient perfusion to extremities
• Patient activity level
• Available application sites on the patient’s body
• Sterility requirements
• Anticipated duration of monitoring
To help ensure optimal and accurate performance:
• Use a dry and appropriately sized sensor.
• Keep the sensor site at the same level as the patient’s heart.
• Apply the sensor according to the Directions for Use provided with the sensor.
• Observe all warnings and cautions noted in the sensor’s Directions for Use.
The sensors are sensitive to light. If excessive ambient light is present (such as sunlight, surgical
lights, or bilirubin lamp), cover the sensor site with an opaque material to block the light. Failure
to do so could result in inaccurate measurements.
If patient movements present a problem, consider the following possible solutions:
• Be sure the sensor is secure and properly aligned.
• Use a new sensor with fresh adhesive backing.
• If possible, move the sensor to a less active site.
Note: Wrapping the sensor too tightly or using supplemental tape to hold the sensor in place
may cause inaccurate measurements.

Monitoring
SpO2 Monitoring Procedure
The defibrillator controls power to the pulse oximeter. When the defibrillator is turned on, the
oximeter turns on and performs a self-test that requires up to 10 seconds. When the defibrillator
is turned off, the oximeter also turns off.
To conserve battery power, the pulse oximeter goes into “sleep mode” when not in use. Sleep
mode is activated within 10 seconds of disconnecting the sensor. During sleep mode, the screen
does not display SpO2 information. The oximeter returns to normal mode after detecting a sensor
or a patient signal. The oximeter performs the self-test when it returns from sleep mode to active
mode.
The pulse oximeter measures SpO2 levels between 1% and 100%. When SpO2 levels are
between 70% and 100%, oximeter measurements are accurate within ±3 digits. When the pulse
oximeter measures SpO2 levels less than 50%, the display shows < 50%.
To measure the patient’s SpO2 levels:
1 Connect the SpO2 cable to the monitor.
2 Attach the sensor to the SpO2 cable and the patient.
3 Press ON.
4 Observe the pulse bar for fluctuation. Amplitude of the pulse bar indicates relative signal
quality.
5 Adjust sensitivity, averaging time, and SpO2 volume as necessary.
SpO2 Waveform
The SpO2 waveform can be displayed on waveform Channel 2 by selecting waveform Channel 2
and then selecting SpO2 from the Waveform menu. The SpO2 waveform automatically sizes itself
to provide optimum waveform viewing.
SpO2 Volume
To adjust the pulse tone volume, highlight and select SPO2 on the home screen.
The following overlay appears:
1 Highlight and select SPO2 VOLUME.
2 Rotate the Speed Dial to the desired

LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Monitoring
The sensitivity setting allows you to adjust the oximeter for differing perfusion states. To adjust
the sensitivity to either normal or high, highlight and select SPO2 on the home screen and then
select SENSITIVITY.
The normal sensitivity setting is the recommended setting for most patients. The high sensitivity
setting allows for SpO2 monitoring under low perfusion states such as the severe hypotension of
shock. However, when the SpO2 sensitivity is set to high, the signal is more susceptible to
artifact. It is recommended that the patient be monitored closely when the high sensitivity setting
is in use.
Averaging Time
The averaging time setting allows you to adjust the time period used to average the SpO2 value.
Four time periods are provided for averaging: 4, 8, 12, and 16 seconds. To adjust the averaging
time, highlight and select SPO2 on the home screen and select AVERAGING TIME.
The averaging time of 8 seconds is recommended for most patients. For patients with rapidly
changing SpO2 values, the 4-second time is recommended. The 12- and 16-second periods are
used when artifact is affecting the performance of the pulse oximeter.

The EtCO2 monitor is intended only as an adjunct in patient assessment and is not to be used as
a diagnostic apnea monitor. An apnea message appears if a valid breath has not been detected
for 30 seconds and indicates the time elapsed since the last valid breath. It must be used in
conjunction with clinical signs and symptoms.
Possible inaccurate CO2 readings.
Using other manufacturers’ CO2 accessories may cause the device to perform improperly and
invalidate the safety agency certifications. Use only the accessories that are specified in these
operating instructions.
Possible inaccurate CO2 readings.
If calibration is not performed as specified in the Service Manual for the LIFEPAK 20e
defibrillator/monitor, the EtCO2 monitor may be out of calibration. A monitor that is out of
calibration may provide inaccurate readings.

WARNINGS! (CONTINUED)
Possible strangulation.
Carefully route the patient tubing (FilterLine) to reduce the possibility of patient entanglement or
strangulation.
Infection hazard
Do not reuse, sterilize, or clean Microstream® CO2 accessories as they are designed for singlepatient one-time use.
How Capnography Works
An EtCO2 sensor continuously monitors carbon dioxide (CO2) that is inspired and exhaled by the
patient. The sensor employs Microstream non-dispersive infrared (IR) spectroscopy to measure
the concentration of CO2 molecules that absorb infrared light.
The CO2 FilterLine system delivers a sample of the exhaled gases directly from the patient into
the CodeManagement Module for CO2 measurement. The low sampling flow rate (50 ml/min)
reduces liquid and secretion accumulation and prevents obstruction, which maintains the shape
of the CO2 waveform.
The CO2 sensor captures a micro sample (15 microliters). This extremely small volume allows for
fast rise time and accurate CO2 readings, even at high respiration rates.
The Microbeam IR source illuminates the sample cell and the reference cell. This proprietary IR
light source generates only the specific wavelengths characteristic of the CO2 absorption
spectrum. Therefore, no compensations are required when concentrations of O2, anesthetic
agent, or water vapor are present in the exhaled breath.
The LIFEPAK 20e defibrillator/monitor is set at the factory to use the capnography Body
Temperature Pressure Saturated (BTPS) conversion method. This option corrects for the
difference in temperature and moisture between the sampling site and alveoli. The correction
formula is 0.97 x the measured EtCO2 value. The BTPS conversion can be turned off in the
Setup Options. Refer to "CO2 Setup Menu," page 8-10, for more information.
EtCO2 Monitoring Waveform Analysis
Valuable information concerning the patient’s expired CO2 can be acquired by examination and
interpretation of the waveform.
The Phases of the Waveform
Figure 3-5 is a graphic representation of a normal capnograph waveform. Four phases of the
waveform require analysis. The flat I–II baseline segment (Respiratory Baseline) represents
continued inhalation of CO2-free gas. This value normally is zero. The II–III segment (Expiratory
Upstroke), a sharp rise, represents exhalation of a mixture of dead space gases and alveolar
gases from acini with the shortest transit times. Phase III–IV (Expiratory Plateau) represents the
alveolar plateau, characterized by exhalation of mostly alveolar gas. Point IV is the end-tidal
(EtCO2) value that is recorded and displayed by the monitor. Phase IV–V (Inspiratory
Downstroke), a sharp fall, reflects the inhalation of gases that are CO2-free. Alterations of the
normal capnograph or EtCO2 values are the result of changes in metabolism, circulation,
ventilation, or equipment function.

Figure 3-5 Phases of the Respiratory Waveform
Respiratory Baseline. Elevation of the waveform baseline (I–II segment) usually represents
rebreathing CO2. This elevation usually is accompanied by gradual increases in the EtCO2 value.
Rebreathing CO2 is common in circumstances of artificially produced increased dead space and
hypoventilation. Precipitous rises in both baseline and EtCO2 values usually indicate
contamination of the sensor.
Expiratory Upstroke. In the normal waveform, the rising phase (II–III segment) is usually steep.
When this segment becomes less steep, CO2 delivery is delayed from the lungs to the sampling
site. The causes of this delay can be physiologic or mechanical and include bronchospasm,
obstruction of the upper airway, or obstruction (or kinking) of an endotracheal tube (ETT).
Expiratory Plateau. The plateau of the waveform, which represents the remainder of expiration
(III-IV segment), should be nearly horizontal. The end of the plateau represents the EtCO2 value.
Upward slanting of the expiratory plateau occurs when there is uneven emptying of the alveoli.
Similar to the diminished slope of the Expiratory Upstroke, this pattern can occur in asthma,
chronic obstructive pulmonary disease (COPD), partial upper-airway obstruction, or partial
mechanical obstruction such as a partially kinked ETT.
Inspiratory Downstroke. The fall to baseline (IV-V segment) is a nearly vertical drop. This slope
can be prolonged and can blend with the expiratory plateau in cases of leakage in the exhale
portion of the breathing circuit. The peak EtCO2 value (IV) is often not reached. Relying on the
numeric end-tidal value without observing the breathing waveform may obscure the presence of
a leak.
EtCO2 Monitoring Procedure
The EtCO2 monitor is activated when the FilterLine set is attached. Initialization, self-test, and
warm-up of the EtCO2 monitor is typically less than 30 seconds, but may take up to two and
one-half minutes.
Carefully read the Instructions for Use that are provided with the FilterLine for placement
instructions, use instructions, warnings, cautions, and specifications.
CAUTION!
Possible equipment damage.
Failure to replace a broken or missing CO2 port door may allow water or particulate
contamination of the internal CO2 sensor. This may cause the CO2 module to malfunction.
Possible equipment damage.
Do not use excessive force when connecting the FilterLine to the CO2 port. This may damage
the connector.
To monitor EtCO2:
1 Press ON.
2 Select the appropriate EtCO2 accessory for the patient.
3-18
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Monitoring
3 Open the CO2 port door and insert the FilterLine connector. Using the tabs, screw the
FilterLine connector into the CO2 port clockwise until it can no longer be turned. Do not use
excessive force.
4 Verify that the CO2 area is displayed. The EtCO2 monitor performs the autozero routine as
part of the initialization self-test.
Note: If you use a ventilation system, do not connect the FilterLine set to the patient/
ventilation system until the EtCO2 monitor has completed its self-test and warm-up.
5 Display CO2 waveform in Channel 2.
6 Connect the CO2 FilterLine set to the patient.
7 Confirm that the EtCO2 value and waveform are displayed. The monitor automatically selects
the scale for the best visualization of the waveform. You can change the scale, if desired, as
described in the next section.
Note: It is possible for the FilterLine set to become loose at the device connection and still
have an EtCO2 value and CO2 waveform, but they may be erroneously low. Make sure the
FilterLine connection is firmly seated and can no longer be turned.
Note: The capnography module performs self-maintenance within the first hour of monitoring
and once an hour during continuous monitoring. The self-maintenance includes “autozeroing.” Self-maintenance is also initiated when the surrounding temperature changes 8°C
(14.4°F) or more, or the surrounding pressure changes more than 20 mmHg. The CO2
module detects this change and attempts to purge the tubing. To clear the CO2 FILTERLINE
PURGING or CO2 FILTERLINE BLOCKAGE messages, remove the FilterLine tubing and
reconnect it to the monitor.

Monitoring
CO2 Display
The following scales are available to display the CO2 waveform. The LIFEPAK 20e
defibrillator/monitor automatically selects the scale based on the measured EtCO2 value. To
change the CO2 scale, outline and select the CO2 area using the Speed Dial and then select the
desired scale from the scale menu.
• Autoscale (default)
• 0–20 mmHg (0–4 Vol% or kPa)
• 0–50 mmHg (0–7 Vol% or kPa)
• 0–100 mmHg (0–14 Vol% or kPa)
The CO2 waveform is compressed (displayed at 12.5 mm/sec sweep speed) to provide more data
in the 3.7-second screen. There is a slight delay between when the breath occurs and when it
appears on the screen. Printouts are at 25 mm/sec.
The monitor shows the maximum CO2 value over the last 20 seconds. If the EtCO2 values are
increasing, the change can be seen with every breath. However, if the values are continually
decreasing, it will take up to 20 seconds for a lower numerical value to be displayed. Because of
this, the EtCO2 value may not always match the level of the CO2 waveform.
CO2 Alarms
The EtCO2 monitor provides:
• EtCO2 high and low alarms (controlled by activating Alarms (refer to "Setting Alarms,"
page 2-17)).
• FiCO2 (inspired CO2) alarm (controlled by activating Alarms; automatically set to default values
and not adjustable)
• Apnea alarm (automatic and not adjustable)
• Respiration Rate high and low alarms (controlled by activating Alarms (refer to "Setting
Alarms," page 2-17)).
Note: The apnea alarm occurs when a breath has not been detected for 30 seconds. The
message ALARM APNEA appears in the message area along with the time since the last
detected breath.
3-20
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Monitoring
A CO2 waveform appears when any CO2 is detected, but CO2 must be greater than 3.5 mmHg for
a numerical value to be displayed. However, the CO2 module will not recognize a breath until the
CO2 is at least 8 mmHg (1.0% or 1 kPa). Valid breaths must be detected in order for the apnea
alarm to function and to count the respiratory rate (RR).
When CO2 is not detected in the cardiac arrest situation—for example, the CO2 waveform is
either dashes “---” or a flat solid line at or near zero—several factors must be quickly evaluated.
Assess for the following causes:
Equipment Issues
• FilterLine set is disconnected from the endotracheal tube (ETT)
• System is purging due to fluid in the patient/sensor connection from ET administration of
medications
• System is auto-zeroing
• FilterLine connection to device is loose
Loss of Airway Function
• Improper placement of ETT
• ETT dislodgment
• ETT obstruction
Physiological Factors
• Apnea
• Loss of perfusion
• Exsanguination
• Massive pulmonary embolism
• Inadequate CPR
Cleaning
Accessories for CO2 monitoring are disposable and are intended for single-patient use. Do not
clean and reuse a FilterLine set. Dispose of the contaminated waste according to local protocols.

GENERAL THERAPY WARNINGS AND CAUTIONS
WARNINGS!
Shock hazard.
The defibrillator delivers up to 360 J of electrical energy. When discharging the defibrillator, do
not touch the paddle electrode surfaces or disposable therapy electrodes.
Shock hazard.
If a person is touching the patient, bed, or any conductive material in contact with the patient
during defibrillation, the delivered energy may be partially discharged through that person. Clear
everyone away from contact with the patient, bed, and other conductive material before
discharging the defibrillator.
Shock hazard.
Do not discharge the defibrillator into the open air. To remove an unwanted charge, change the
energy selection, select disarm, or turn off the defibrillator.
Possible fire, burns, and ineffective energy delivery.
Do not discharge standard paddles on top of therapy electrodes or ECG electrodes. Do not allow
standard paddles (or therapy electrodes) to touch each other, ECG electrodes, lead wires,
dressings, transdermal patches, etc. Such contact can cause electrical arcing and patient skin
burns during defibrillation and may divert defibrillating energy away from the heart muscle.
Possible defibrillator shutdown.
When operating on battery power, adhere to battery maintenance and replacement intervals
discussed in the Battery Performance and Life section to prevent possible defibrillator shutdown.
If the defibrillator shuts down without warning, or if a LOW BATTERY: CONNECT TO AC POWER
message appears on the monitor screen, immediately connect the AC power cord to an outlet.
Possible skin burns.
During defibrillation or pacing, air pockets between the skin and therapy electrodes may cause
patient skin burns. Apply therapy electrodes so that entire electrode adheres to skin. Do not
reposition the electrodes once applied. If the position must be changed, remove and replace with
new electrodes.
Possible skin burns and ineffective energy delivery.
Therapy electrodes that are dried out or damaged may cause electrical arcing and patient skin
burns during defibrillation. Do not use therapy electrodes that have been removed from foil
package for more than 24 hours. Do not use electrodes beyond expiration date. Check that
electrode adhesive is intact and undamaged. Replace therapy electrodes after 50 shocks.
Possible interference with implanted electrical device.
Defibrillation may cause implanted devices to malfunction. Place standard paddles or therapy
electrodes away from implanted devices if possible. Check implanted device function after
defibrillation.
CAUTION!
Possible equipment damage.
Prior to using this defibrillator, disconnect all equipment from the patient that is not defibrillatorprotected.

THERAPY ELECTRODE AND STANDARD PADDLE PLACEMENT
The following paragraphs describe therapy electrodes and standard paddles placement,
including special placement situations.
Anterior-lateral Placement
Anterior-lateral placement allows for ECG monitoring, defibrillation, synchronized cardioversion,
and noninvasive pacing.
1 Place either the ♥ or + therapy electrode, or apex paddle lateral to the patient's left nipple in
the midaxillary line, with the center of the electrode in the midaxillary line, if possible. Refer to
Figure 4-1.

2 Place the other therapy electrode or sternum paddle on the patient’s upper right torso, lateral
to the sternum, and below the clavicle as shown in Figure 4-1.
Anterior-posterior Placement
Anterior-posterior is an alternative position for noninvasive pacing, manual defibrillation, and
synchronized cardioversion, but not for ECG monitoring or automated defibrillation. The ECG
signal obtained through electrodes in this position is not a standard lead. (For pediatric
applications, see "Pediatric Defibrillation," page 4-21.)
1 Place either the ♥ or + therapy electrode over the left precordium as shown in Figure 4-2. The
upper edge of the electrode should be below the nipple. Avoid placement over the nipple, the
diaphragm, or the bony prominence of the sternum if possible.
2 Place the other electrode behind the heart in the infrascapular area as shown in Figure 4-2.
For patient comfort, place the cable connection away from the spine. Do not place the
electrode over the bony prominences of the spine or scapula.

Special Placement Situations
When placing therapy electrodes or standard paddles, be aware of the special requirements in
the following possible situations.
Synchronized Cardioversion
Alternative anterior-posterior placements for cardioversion of supraventricular arrhythmias
include:
• Place the ♥ or + therapy electrode over the left precordium and the other electrode on the
patient’s right posterior infrascapular area
– or –
• Place the ♥ or + therapy electrode to the right of the sternum and the other electrode on the
patient’s posterior left infrascapular area.
Obese Patients or Patients with Large Breasts
Apply therapy electrodes or standard paddles to a flat area on the chest, if possible. If skin folds
or breast tissue prevent good adhesion, it may be necessary to spread skin folds apart to create
a flat surface.
Thin Patients
Follow the contour of the ribs and spaces when pressing the therapy electrodes onto the torso.
This limits air spaces or gaps under the electrodes and promotes good skin contact.
Patients with Implanted Pacemakers
If possible, place therapy electrodes or standard paddles away from the internal pacemaker
generator to help prevent damage to the pacemaker. Treat the patient like any other patient
requiring care. When operating the defibrillator in AED mode, pacemaker pulses may prevent
advisement of an appropriate shock, regardless of the patient’s underlying rhythm.
Patients with Implanted Defibrillators
Apply therapy electrodes or standard paddles in the anterior-lateral position and treat this patient
as any other patient requiring emergency care. If defibrillation is unsuccessful, it may be
necessary to try alternate electrode placement (anterior-posterior) due to the insulative
properties of implanted defibrillator electrodes.

Manual Defibrillation Warnings
WARNINGS!
Possible fire, burns, and ineffective energy delivery.
Precordial lead electrodes and lead wires may interfere with the placement of standard paddles
or therapy electrodes. Before defibrillation, remove any interfering precordial lead electrodes
and lead wires.
Shock hazard.
Conductive gel (wet or dry) on the paddle handles can allow the electrical energy to discharge
through the operator during defibrillation. Completely clean the paddle electrode surfaces,
handles, and storage area after defibrillation.
Possible patient skin burns.
Possible paddle damage and patient skin burns.
Discharging the defibrillator with the standard paddle surfaces shorted together can pit or
damage the paddle electrode surface. Pitted or damaged paddle surfaces may cause patient
skin burns during defibrillation. Discharge the defibrillator only as described in these operating
instructions.
Possible burns and ineffective energy delivery.
A gel pathway on the skin between the standard paddles will cause defibrillating energy to arc
between paddles and divert energy away from the heart muscle. Do not allow conductive gel
(wet or dry) to become continuous between paddle sites.
Possible damage to defibrillator and defibrillator shutdown.
When used in conjunction with another defibrillator to deliver more than 360J, one or both
defibrillators may be damaged and shutdown may occur due to excessive currents. Avoid
simultaneous discharge from both defibrillators and maintain a backup defibrillator in case one
or both defibrillators shut down. If the defibrillator shuts down, take the defibrillator out of service
and contact a qualified service technician.
To use the LIFEPAK 20e defibrillator/monitor primarily as a manual defibrillator, configure the
defibrillator before placing the defibrillator in use. To configure the defibrillator, refer to Section 8.
Impedance
LIFEPAK biphasic defibrillators measure the patient's transthoracic impedance and automatically
adjust the defibrillation waveform voltage and current duration to meet the needs of the individual
patient.
Impedance is measured whenever the defibrillator is charged. To ensure correct patient
impedance readings, you should always charge the defibrillator when the standard paddles (hard
paddles) or QUIK-COMBO electrodes are in contact with the patient's chest.
If the standard paddles are in the paddle wells or touching face to face (shorted paddles) when
the defibrillator is charged, the defibrillator limits the available energy to 79 joules This prevents
damage to the internal circuits, in the event the energy is discharged while the hard paddles are
still in the paddle wells or shorted together. If the defibrillator is charged to 80 joules or more and
energy is discharged when the hard paddles are seated in the paddle wells, the display indicates
the selected energy available and the automatic printout annotates time, date and Shock 1 79 J.

4 Therapy
During defibrillation, air pockets between the skin and standard paddles can cause patient skin
burns. Completely cover paddle electrode surfaces with fresh conductive gel and apply 11.3 kg
(25 lb) of pressure per paddle during discharge.
Therapy
If the defibrillator is charged to 80 joules or more with paddles in the paddle wells, and then the
paddles are removed and placed on a patient, the defibrillator continues charging to the selected
energy and defibrillation may be completed as usual. When charging the defibrillator with the
paddles on the patient’s chest, the defibrillator automatically adjusts the waveform voltage and
current duration based on the patient's impedance. It is important to understand that this
automatic adjustment does not occur when the defibrillator is charged with the paddles seated in
the paddle wells.
When the paddles or QUIK-COMBO electrodes are on the patient's chest when the defibrillator is
charged and the defibrillator measures an impedance of 15 ohms or less, the defibrillator disarms
the capacitor and automatically recharges to a lower energy setting. When this condition occurs,
the LOW IMPEDANCE-RECHARGING message appears on the display. When charging is
complete, defibrillation may be completed as usual.
Defibrillation Procedure
You can configure the LIFEPAK 20e defibrillator/monitor to automatically sequence energy
levels. Refer to "Manual Mode Setup Menu," page 8-5.
1 Press ON.
2 Identify the electrode or paddle sites on the patient. Use either the anterior-lateral or anteriorposterior position as described on page 4-3.
3 Prepare the patient’s skin for electrode application:
• If possible, place the patient on a firm surface away from standing water.
• Remove clothing from the patient’s upper torso.
• Remove excessive hair from the electrode sites; if shaving is necessary, avoid cutting the
skin.
• Clean the skin and dry it briskly with a towel or gauze.
• Do not apply alcohol, tincture of benzoin, or antiperspirant to the skin.
4 Connect the therapy electrodes to the therapy cable, and confirm cable connection to the
defibrillator.
Note: When in PADDLES lead, if the REMOVE TEST PLUG message appears, disconnect
test plug and connect therapy electrodes to QUIK-COMBO therapy cable.
5 Apply therapy electrodes to the patient in anterior-lateral or anterior-posterior position. If using
standard paddles, apply conductive gel to the paddles and place paddles on the patient’s
chest.
6 Press ENERGY SELECT.
7 Press CHARGE. While the defibrillator is charging, a charging bar appears and a ramping tone
sounds, indicating the charging energy level. When the defibrillator is fully charged, an overlay
appears (refer to "Defibrillation Procedure," page 4-16).
8 Make certain all personnel, including the operator, stand clear of the patient, bed, and any
equipment connected to the patient.
9 Confirm ECG rhythms and available energy.
10 Press the SHOCK button on the defibrillator or the SHOCK buttons on the standard paddles to
discharge energy to the patient. For standard paddles, apply firm pressure with both paddles to
the patient’s chest, and press both paddle buttons simultaneously to discharge energy to the
patient. For safety reasons, the SHOCK button on the defibrillator front panel is disabled when
using standard paddles.
Note: To disarm (cancel the charge), press the Speed Dial. The defibrillator disarms
automatically if shock buttons are not pressed within 60 seconds, or if you change the
energy selection after charging begins. Press CHARGE to restart charging.

11 Observe the patient and the ECG rhythm. If an additional shock is necessary, repeat the
procedure beginning at Step 6.
Note: If the ABNORMAL ENERGY DELIVERY message appears and the shock is not
effective, increase energy, if necessary, and repeat shock. (Also refer to page 4-24.)
CPR Metronome
When CPR is required during cardiac arrest, the CPR metronome provides audible prompts that
guide the user to deliver CPR with proper timing in accordance with the 2010 American Heart
Association and European Resuscitation Council CPR guidelines.
CPR Metronome Warnings
WARNING!
CPR Delivered When Not Needed.
4 Therapy
The metronome sounds do not indicate information regarding the patient’s condition. Because
patient status can change in a short time, the patient should be assessed at all times. Do not
perform CPR on a patient who is responsive or is breathing normally.
Note: The CPR metronome is a tool to be used as a timing aid during CPR. Assess the
patient at all times and provide CPR only when indicated. Provide CPR according to your
training and protocols.
How the CPR Metronome Works
The metronome provides audible “tocks” at a rate of 100/minute to guide the rescuer in
performing chest compressions. The metronome also provides audible ventilation prompts
(either a tone or verbal “ventilate”) to cue the rescuer when to provide ventilations. The
metronome prompts the rescuer to perform CPR at the selected compression to ventilation (C:V)
ratio.
Age-Airway Considerations
The default C:V ratio for the metronome (in both AED and Manual modes) is Adult - No Airway
(30:2) because most patients in cardiac arrest are adults who have an initially unsecured airway.
In Manual mode, the user can choose the most appropriate C:V ratio based on the patient’s age
and current airway status. The Age-Airway selection determines the C:V ratio of the metronome
sounds. The default C:V ratios are shown in Table 4-2.
Table 4-2 Default Age-Airway C:V Ratios in Manual Mode

Activating and Deactivating the Metronome
To activate the CPR metronome in Manual mode:
CPR Metronome
Adult - No Airway
Adult - Airway
Youth - No Airway
Youth - Airway
Stop Metronome
Adult - No Airway 30:2
1 Use the Speed Dial to select the CPR
METRONOME icon. The CPR
Metronome menu appears and the
metronome is activated using the AdultNo Airway default setting.
2 Use the Speed Dial to highlight and
select the desired Age-Airway setting.
When the metronome is on, a message
appears in the message area that indicates
the current Age-Airway selection.
Note: The CPR metronome cannot be activated during noninvasive pacing.
Note: If the VF/VT alarm is on, it is suspended when the metronome is on to prevent false
VF/VT alarms. If other vital sign alarms activate when the metronome is on, the visual
indicators occur, but the alarm tone is suppressed until the metronome is deactivated.
The metronome provides “tocks” and ventilation prompts continuously until it is deactivated. To
stop the metronome, select STOP METRONOME in the CPR Metronome menu. An event is
recorded in the CODE SUMMARY Event Log when CPR metronome is turned ON or OFF and
when the Age-Airway setting is changed. To adjust the volume of the metronome, press
OPTIONS, select ALARM VOLUME, and change the VOLUME.
Note: If all Age-Airway selections are set to the same C:V ratio (for example, Adult - No
Airway, Adult - Airway, Youth - No Airway, and Youth - Airway all set to 10:1), the CPR
metronome always provides “tocks” and ventilation prompts at the set ratio for both AED
mode and Manual mode. In this situation, the CPR Metronome menu does not appear when
the CPR METRONOME icon is selected during use—selecting the CPR METRONOME icon only
activates and deactivates the metronome at the fixed C:V ratio.
Synchronized Cardioversion Procedure
Note: The LIFEPAK 20e defibrillator/monitor can be configured to remain in synchronous
mode or to return to asynchronous mode after discharge. It is important that you know how
your defibrillator is configured. Refer to "Manual Mode Setup Menu," page 8-5.
1 Press ON.
2 Attach patient ECG cable and ECG electrodes as described previously on page 3-5.

Remote Synchronization Procedure
WARNINGS!
Possible lethal arrhythmia.
Ventricular fibrillation may be induced with improper synchronization. The hospital’s biomedical
engineering staff should perform synchronization delay measurements on the system, as a
whole, to ensure that the 60 ms limit for synchronization delay is not exceeded, per requirements
as specified in AAMI DF2 (1996). Always confirm proper placement of the sense markers on the
ECG.
Possible monitor incompatibility
If the R-wave synchronization markers do not appear to be nearly simultaneous with the Rwaves on the remote monitor display or are not present, do not proceed with synchronized
cardioversion.
The LIFEPAK 20e defibrillator/monitor can be configured to receive an ECG source from a
remote monitor (such as a bedside ECG monitoring system) by means of the ECG/Sync
connector on the back of the defibrillator/monitor. Refer to "Manual Mode Setup Menu,"
page 8-5. The remote monitor must have a sync out connector and a cable must be provided to
make this connection. Refer to the LIFEPAK 20e Defibrillator/Monitor Service Manual for more
details.
Note: The LIFEPAK 20e defibrillator/monitor can be configured to remain in synchronous
mode or to return to asynchronous mode after discharge. It is important that you know how
your defibrillator is configured. Refer to "Manual Mode Setup Menu," page 8-5.
To perform the synchronized cardioversion using a remote monitoring ECG source:
1 Ensure defibrillator/monitor is connected to AC power.
2 Connect the sync cable to the defibrillator/monitor ECG/Sync connector and the remote
monitor.
3 Press ON.
4 Attach the ECG cable from the remote monitor to the patient.
5 Press SYNC on the defibrillator/monitor.
6 Select REMOTE SYNC from the menu.
Note: The screen on the defibrillator/monitor will display the message REMOTE SYNC in
place of any waveforms.
7 Observe the ECG rhythm on the remote monitor. Confirm that a sense marker appears above

PEDIATRIC DEFIBRILLATION
Pediatric paddles are part of the standard paddle set (refer to page 5-7).
Pediatric Paddle Placement
Pediatric paddles should be used for patients weighing less than 10 kg (22 lb) or for patients
whose chest size cannot accommodate the adult therapy electrodes.
Adult paddles are recommended if the paddles will fit completely on the patient’s chest. Allow at
least 2.5 cm (1 in.) of space between the paddles.
For neonates with very small chests, pediatric paddles may be too large to place in the anteriorlateral position. In this situation, place paddles in the anterior-posterior position. Holding the
paddles against the chest and back will support the patient on his/her side.
Anterior-Lateral
The following is the standard pediatric paddle placement (refer to Figure 4-3):
• Sternum paddle to the patient’s right upper torso, lateral to the sternum and below the clavicle.
• Apex paddle lateral to the patient’s left nipple in the midaxillary line, with the center of the
paddle in the midaxillary line if possible.

Sinus bradycardia may be physiologic in severe hypothermia (i.e., appropriate to maintain
sufficient oxygen delivery when hypothermia is present), and cardiac pacing is usually not
indicated.
Possible interruption of therapy.
Observe the patient continuously while the pacemaker is in use. Patient response to pacing
therapy, e.g., capture threshold, may change over time.
Possible inability to pace.
Using other manufacturers’ combination therapy electrodes with this device could cause a
decrease in pacing efficacy or the inability to pace because of unacceptably high impedance
levels.
Possible patient skin burns.
Prolonged noninvasive pacing may cause patient skin irritation and burns, especially with higher
pacing current levels. Discontinue noninvasive pacing if skin becomes burned and another
method of pacing is available.
Demand and Nondemand Pacing
The noninvasive pacemaker can be used for either demand (synchronous) or nondemand
(asynchronous) pacing modes.
The demand mode is used for most patients. In the demand mode, the LIFEPAK 20e defibrillator/
monitor/pacemaker inhibits pacing when it senses the patient’s own beats (intrinsic QRSs). In
demand mode, if the ECG amplitude is too low to detect the patient’s beats, or if an ECG lead
becomes detached so that the ECG rhythm is not present, the pacemaker generates pacing
pulses asynchronously. This means that the pacemaker generates pacing pulses at the selected
rate, regardless of the patient’s ECG rhythm.
Asynchronous or nondemand mode can be selected if noise or artifact interferes with proper
sensing of QRS complexes. Press the OPTIONS button to access the nondemand mode. (Refer
to page 2-7.)

Therapy
The LIFEPAK 20e defibrillator/monitor has an integrated pulse oximeter that can be used in
conjunction with a noninvasive pacemaker to help confirm capture. To confirm capture, compare
the pulse rate measured by the oximeter to the set pacing rate of the pacemaker.
Noninvasive Pacing Procedure
ECG monitoring during pacing must be performed with the ECG electrodes and patient ECG
cable. Pacing therapy electrodes cannot be used to monitor ECG rhythm and deliver pacing
current at the same time. Be sure to place the therapy electrodes in the proper locations as
described in the pacing procedure. Improper electrode placement may make a difference in the
capture threshold.
To pace, perform the following:
1 Press ON.
2 Connect the patient ECG cable, apply ECG electrodes to the ECG cable and patient, and
select Lead I, II, or III. To receive the best monitoring signal, ensure there is adequate space
between the ECG electrodes and the therapy electrodes.
3 Identify the QUIK-COMBO electrode sites on the patient. For pacing, use either the anteriorlateral or anterior-posterior position (refer to page 4-3).
4 Prepare patient's skin for electrode application as described in Step 3 of the Defibrillation
Procedure.
5 Apply QUIK-COMBO electrodes to the patient.
6 Connect the therapy electrodes to the therapy cable.
7 Press PACER. Confirm the LED illuminates, indicating that the power is on.
Note: If the REMOVE TEST PLUG message appears, disconnect test plug and connect
therapy electrodes to QUIK-COMBO therapy cable.
8 Observe the ECG rhythm. Confirm that a triangle sense marker appears near the middle of
each QRS complex. If the sense markers do not appear or are displayed in the wrong location
(for example, on the T-wave), select another lead. (It is normal for the sense marker location
to vary slightly on each QRS complex.)
9 Press RATE or rotate the Speed Dial to select the desired pacing rate.
Note: The RATE button changes the rate in 10 pulse per minute (ppm) increments; the
Speed Dial changes the rate in 5 ppm increments.
10 Press CURRENT or rotate the Speed Dial to increase current until electrical capture occurs.
For each delivered pacing stimulus, the PACER indicator flashes off and a positive pace
marker displays on the ECG waveform.
11 Palpate the patient's pulse or check blood pressure and compare the SpO2 pulse rate with the
set pacing rate to assess for mechanical capture. Consider use of sedation or analgesia if
patient is uncomfortable.
Note: The CURRENT button changes the current in 10 mA increments; the Speed Dial
changes the current in 5 mA increments.
Note: To change rate or current during pacing, press RATE or CURRENT, and then rotate
the Speed Dial.
Note: To interrupt pacing and view the patient's intrinsic rhythm, press and hold the
PAUSE button. This causes the pacer to pace at 25% of the set rate. Release the PAUSE
button to resume pacing at the set rate.
12 To stop pacing, reduce current to zero or press PACER.
Note: To defibrillate and stop noninvasive pacing, press ENERGY SELECT or charge the
defibrillator. Pacing automatically stops. Proceed with defibrillation.
4-26
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Therapy
If the monitor detects ECG leads off during pacing, pacing continues at a fixed rate until the ECG
lead is reattached. During fixed-rate pacing, the pacemaker delivers pulses at the set pace rate
regardless of any intrinsic beats that the patient may have. The monitor continues to display the
pacing rate (ppm) and the current (mA). To reestablish demand pacing, reattach the ECG lead.
While pacing, visually monitor the patient at all times, do not rely on the ECG LEADS OFF warning
to detect changes in pacing function. Routinely assess the ECG for proper sensing, pace pulse
delivery, electrical capture, and mechanical capture.
If pacing electrodes detach during pacing, the CONNECT ELECTRODES and PACING STOPPED
messages appear and an alarm sounds. The pacing rate is maintained and the current resets to
0 mA. Reattaching the pacing electrodes silences the alarm and removes the CONNECT
ELECTRODES message. The current remains at 0 mA until you increase the current manually.

About Therapy Electrodes
There are two pre-gelled, self-adhesive therapy electrodes available: QUIK-COMBO pacing/
defibrillation/ECG electrodes and FAST-PATCH defibrillation/ECG electrodes (Figure 5-1).
QUIK-COMBO electrodes are used for defibrillation, synchronized cardioversion, ECG
monitoring, and pacing. FAST-PATCH electrodes can be used for defibrillation, synchronized
cardioversion, and ECG monitoring, but not for pacing. To use FAST-PATCH electrodes with the
LIFEPAK 20e defibrillator/monitor requires the addition of a FAST-PATCH defibrillation adapter
cable.
Figure 5-1 QUIK-COMBO and FAST-PATCH Electrodes
A QUIK-COMBO or FAST-PATCH electrode set:
• Is a substitute for standard paddles.
• Provides a Lead II monitoring signal when placed in the anterior-lateral position.
• Quickly restores the ECG trace on the monitor following defibrillation.
To help prevent electrode damage:
• Do not fold the electrodes.
• Do not trim the electrodes.
• Do not crush, fold, or store the electrodes under heavy objects.
• Store therapy electrodes in a cool, dry location. These electrodes are designed to withstand
environmental temperature fluctuations between -40° to 50°C (-40° to 122°F). Continuous
exposure to temperatures above 23°C (73°F) reduces the shelf life of electrodes.
There are several types of QUIK-COMBO electrodes available as described in Table 5-1.

FAST-PATCH electrodes can be used on pediatric patients if the placement meets conditions
noted in the following paragraphs. Usually, these conditions can be met by patients weighing
15 kg (33 lb) or more.
Electrode Placement
When using QUIK-COMBO or FAST-PATCH electrodes, ensure that the electrodes:
• Fit completely on the chest as described on page 3-4 or page 4-3.
• Have at least 2.5 cm (1 in.) of space between electrodes.
• Do not overlap bony prominences of sternum or spine.
To place the electrodes:
Figure 5-2 Peeling the Liner from the Electrode
3 Place the electrodes in the anterior-lateral or anterior-posterior position, as described on
page 3-4 or page 4-3, depending on the therapy to be provided and special placement
considerations.
4 Starting from one edge, firmly press the electrode on the patient’s chest to eliminate air
pockets between the gel surface and the skin. Firmly press all adhesive edges to the skin.
Note: Once applied, therapy electrodes should not be repositioned.

5 Paddle Accessory Options
1 Prepare the patient for electrode placement:
• Remove all clothing from the patient’s chest.
• Remove excessive chest hair as much as possible. Avoid nicking or cutting the skin if using
a shaver or razor. If possible, avoid placing the electrodes over broken skin.
• Clean and dry the skin. If there is ointment on the patient’s chest, use soap and water to
clean the skin. Briskly wipe the skin dry with a towel or gauze. This mildly abrades the skin
and removes oils, dirt, and other debris for better electrode adhesion to the skin. Do not use
alcohol, tincture of benzoin, or antiperspirant to prepare the skin.
2 Slowly peel back the protective liner on the electrodes, beginning with the cable connection
end (refer to Figure 5-2).

To properly connect FAST-PATCH electrodes to the FAST-PATCH defibrillation adapter cable
and ensure energy delivery:
1 Attach the defibrillation cable to the electrode post (before applying electrodes to the patient,
when possible).
2 Support the electrode post when attaching the defibrillation cable (refer to Figure 5-4). Firmly
press the cable onto the electrode until a click is heard or felt.
Figure 5-4 Connecting FAST-PATCH Electrodes to Defibrillation Cable
3 Pull up gently on the connector to confirm that the defibrillation cable is securely connected to
the electrode.
Note: If you are reattaching the defibrillation cable to an electrode that is already on the
patient, lift the adhesive edge under the electrode post slightly and place your finger under the
post. Connect the cable as described in the preceding steps.
ECG Monitoring and Therapy Procedures
WARNINGS!
Possible patient skin burns.
Do not use Pediatric QUIK-COMBO electrodes on adults or larger children. Delivery of
defibrillation energies equal to or greater than 100 joules (typically used on adults) through these
smaller electrodes increases the possibility of skin burns.
Possible pediatric patient skin burns.
Noninvasive pacing may cause patient skin irritation and burns, especially with higher pacing
current levels. Inspect underlying skin of the ♥ electrode frequently after 30 minutes of
continuous pacing. Discontinue noninvasive pacing if skin burn develops and another method of
pacing is available. On cessation of pacing, immediately remove or replace electrodes with new
ones.
For adult patients, follow the procedures for ECG monitoring, AED defibrillation, manual
defibrillation, synchronized cardioversion, and pacing described in Section 3 or Section 4.
5-4
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Paddle Accessory Options
For pediatric patients, follow the procedures for ECG monitoring, manual defibrillation,
synchronized cardioversion, and pacing except for the following:
• Select the appropriate defibrillation energy for the weight of the pediatric patient according to
the American Heart Association (AHA) recommendations or local protocol. Using energy
levels of 100 joules or greater is likely to cause burns.
• When pacing, frequently inspect the patient’s skin under the heart electrode for signs of
burns.
Note: The amount of pacing current needed for capture is similar to the pacing current
needed for adults.
Replacing and Removing Electrodes
Replace QUIK-COMBO, QUIK-COMBO RTS, QUIK-COMBO REDI-PAK, or FAST-PATCH Plus
electrodes with new electrodes after 50 defibrillation shocks or 24 hours on the patient’s skin, or
after 8 hours of continuous pacing. Replace pediatric QUIK-COMBO electrodes after 25
defibrillation shocks or 24 hours on the patient’s skin, or after 8 hours of continuous pacing.
To remove QUIK-COMBO or FAST-PATCH electrodes from the patient:
1 Slowly peel back the electrode from the edge, supporting the skin as shown in Figure 5-5.
Figure 5-5 Removing Therapy Electrodes from Skin
2 Clean and dry the patient’s skin.
3 When replacing electrodes, adjust the electrode positions slightly to help prevent skin burns.
4 Close the protective cover on the QUIK-COMBO therapy cable connector when the cable is
not in use.
To disconnect the defibrillation cable from the FAST-PATCH electrodes:
5 Paddle Accessory Options
1 Press down around the electrode post.
2 Pinch the snap connector with the fingers of the other hand and pull straight up (refer to
Figure 5-6).
Figure 5-6 Disconnecting Defibrillation Cable from FAST-PATCH Electrodes
WARNING!
Possible cable damage and ineffective energy delivery or loss of monitoring.
Improper disconnection of the defibrillation cable may damage the cable wires. This can result in
failure to deliver energy or loss of ECG signal during patient care. Position the cable so that it
will not be pulled, snagged, or tripped over. Do not disconnect the defibrillation cable snap
connectors from electrode posts or posts on testing devices by pulling on the cable. Disconnect
the cable by pulling each cable connector straight out (refer to Figure 5-8).

Testing
As part of your defibrillator test routine, inspect and test the QUIK-COMBO therapy cable or
FAST-PATCH defibrillation adapter cable. Daily inspection and testing will help ensure that the
defibrillator and therapy cables are in good operating condition and are ready for use when
needed. (Refer to "Maintaining the Equipment," page 7-1 and the "LIFEPAK® 20e Defibrillator/
Monitor Operator’s Checklist," page D-1.)
Note: During the daily auto test and the user test, energy is discharged through the therapy
cable, testing the defibrillation component of the therapy cable. Performing the therapy cable
test on the Operator's Checklist checks the sensing component of the therapy cable.
Complete therapy cable integrity is checked when both tests are performed.
If you detect any discrepancy during inspection and testing, remove the therapy cable from use
and immediately notify a qualified service technician.
Cleaning and Sterilizing
QUIK-COMBO and FAST-PATCH electrodes are not sterile or sterilizable. They are disposable
and are to be used for a single patient application. Do not autoclave, gas sterilize, immerse in
fluids, or clean electrodes with alcohol or solvents.

OVERVIEW OF DATA STORAGE AND RETRIEVAL
The following paragraphs describe patient data storage and retrieval using the LIFEPAK 20e
defibrillator/monitor.
Data Storage
When you turn on the LIFEPAK 20e defibrillator/monitor, you create a new Patient Record
stamped with the current date and time. All events and associated waveforms are digitally stored
in the Patient Record as patient reports, which you can print. When you turn off the device, the
current Patient Record data is saved in the patient archives.
To access the patient archives, press OPTIONS and select ARCHIVES. You can print, transmit, or
delete patient records stored in the archived Patient Record. When you enter the archives mode,
patient monitoring ends and the current Patient Record is saved and closed. Turn off the device
to exit the archives mode.
Report Types
Patient reports within a Patient Record are stored as a CODE SUMMARY Critical Event Record,
which includes patient information, event and vital signs logs, and waveforms associated with
events (for example, defibrillation) as described on page 6-4.
Memory Capacity
The LIFEPAK 20e defibrillator/monitor retains data for two or more patients when you switch
power off or remove the batteries. The number of patient reports that the defibrillator can store
depends on various factors, including the number of displayed waveforms, the duration of each
use, and the type of therapy. Typically, memory capacity includes up to 100 single waveform
reports. When the defibrillator reaches the limits of its memory capacity, the defibrillator deletes
an entire Patient Record using a “first in, first out” priority to accommodate a new Patient Record.
Deleted Patient Records cannot be retrieved.
CODE SUMMARY REPORT
The LIFEPAK 20e defibrillator/monitor automatically stores a CODE SUMMARY report as part of
the Patient Record for each patient. The report consists of the following:
• Preamble
• Event/vital signs log
• Waveforms associated with certain events

Figure 6-1 CODE SUMMARY Report
Preamble
The preamble contains patient information (name, event identification, patient identification,
location, age, and sex) and device information (date, time, and therapy information) as shown in
Figure 6-1. The event identification is a unique identifier that the defibrillator automatically enters
in the ID field for each Patient Report. This identifier includes the date and time that the
defibrillator is turned on. The location field allows you to enter up to 25 alpha-numeric characters
to identify where the device was used. You can link the data you enter to other patient
information.
Event/Vital Signs Log
The LIFEPAK 20e defibrillator/monitor documents events and vital signs in chronological order.
Events are operator or device actions that are related to monitoring, pacing, AED therapy, data
transmission, and more. Table 6-1 shows a complete listing of events that can be found in the
event log.
Vital signs (or active parameters) are entered into the log automatically every 5 minutes (or for
each event) and when alarm limits are exceeded. Refer to AUTO LOG in Table 8-1 for more
information.

OVERVIEW OF CONNECTIONS FOR TRANSMITTING REPORTS
Patient reports can be transmitted from the LIFEPAK 20e defibrillator/monitor to compatible
Physio-Control data management tools. You can transmit data using either of the following two
methods.
• Wireless connection—the optional CodeManagement Module transmits data via wireless
connection to the LIFENET System. Refer to "Transmitting Archived Patient Records,"
page 6-9, for instructions.
• IrDA connection—an IrDA port, located on the front of the LIFEPAK 20e defibrillator/monitor
(refer to page 2-7), supports wireless, infrared communications for transmitting reports from
the defibrillator to your computer.
Note: When the CodeManagement Module is attached to the LIFEPAK 20e defibrillator/
monitor, the IrDA connection is disabled.
Considerations for IrDA Transmission
You initiate and control IrDA transmission of device data at your computer using Physio-Control
post-event review tools. This includes entering patient information, selecting reports to be
transmitted, and monitoring transmission progress. More information about configuring
Physio-Control post-event review tools and instructions for gathering device data can be found in
the relevant documentation and online help.
To receive an IrDA transmission, your computer must have an operational IrDA port. If your
computer does not have an IrDA port, you can install an IrDA adapter to provide the needed
interface. Physio-Control recommends installing an IrDA adapter on all computers to ensure
successful communication connections and data transmissions.
IrDA adapters are available for serial or USB computer ports. Follow the installation and usage
instructions provided with the adapter, ensuring that the adapter mount (receiving end) is
positioned on a stable surface. Figure 6-3 provides guidelines to follow for positioning the
defibrillator and the IrDA adapter before initiating a transmission.
Note: The shaded cone in Figure 6-3 represents the approximate parameters for positioning
the defibrillator’s IrDA port opposite the IrDA adapter. As the distance between the two
increases, so does the possible range for aligning them.

7 Maintaining the Equipment
This section describes how to perform operator-level maintenance, testing, and troubleshooting
for the LIFEPAK 20e defibrillator/monitor and selected accessories. For additional information
about accessories, refer to specific accessory operating instructions.
Maintaining the Equipment
GENERAL MAINTENANCE AND TESTING
Periodic maintenance and testing of the LIFEPAK 20e defibrillator/monitor and accessories will
help detect and prevent possible electrical and mechanical discrepancies. If testing reveals a
possible discrepancy with the defibrillator or accessories, refer to "General Troubleshooting Tips,"
page 7-10. If the discrepancy cannot be corrected, immediately remove the defibrillator from
service and contact qualified service personnel. For testing information regarding accessories,
refer to the accessory operating instructions.
Each time you turn on the defibrillator/monitor, it performs self tests. If the defibrillator/monitor
detects a failure, the service LED illuminates.
A MAINTENANCE DUE message can be configured to appear on the screen at selected intervals
(3, 6 or 12 months) to remind you that the device is due for maintenance. The factory default is
OFF, but it can be activated by service personnel.
Maintenance and Testing Schedule
Table 7-1 lists the recommended maintenance and testing schedule. This schedule may be used
in conjunction with the internal quality assurance program of the hospital, clinic, or emergency
medical service where the defibrillator is used. An Operator’s Checklist is included in these
operating instructions (refer to Appendix D). Cables and paddles are a critical part of therapy
delivery and suffer wear and tear. Physio-Control recommends replacement of these
accessories every three years to reduce the possibility of failure during patient use.
Additional periodic preventive maintenance and testing, such as electrical safety tests,
performance inspection, and required calibration should be performed regularly by qualified
service personnel.

Maintaining the Equipment
Daily Auto Test
For routine testing and inspection, the user can rely on the daily auto test and the checks
completed using the Operator's Checklist (refer to Appendix D).
Each day at approximately 0300 (3:00am), the LIFEPAK 20e defibrillator/monitor automatically
completes the following tasks:
• Turns itself on
• Performs self-test
• Charges to a low energy level (approximately 1-3 joules) and then discharges through a test
plug or hard paddles
• Tests the pacing circuitry (if noninvasive pacing installed)
• Prints the results, if configured ON
• Transmits the results, if equipped with CodeManagement Module
The daily auto test is not performed if the LIFEPAK 20e defibrillator/monitor is already turned on
at 0300. If you must use the defibrillator while the daily auto test is in progress, press ON to turn
the defibrillator off and press ON again. The test is halted and the LIFEPAK 20e defibrillator/
monitor resumes normal operation.
The daily auto test is a functional test, which checks the defibrillator and pacer circuitry and the
defibrillation component of the therapy cables. This test may take the place of your daily
defibrillator charging and discharging protocol.
It is important that the standard paddles set is securely seated in the paddle wells or that the
QUIK-COMBO therapy cable is connected to the QUIK-COMBO test plug (refer to Figure 7-1) for
the daily auto test to perform properly. There are two reasons why the daily auto test may not
complete. The first is if the standard paddles set is not securely seated in the paddle wells or the
QUIK-COMBO therapy cable is not connected to the QUIK-COMBO test plug (refer to
Figure 7-1). The second is when there is a problem with the therapy cable or the defibrillator.
When the daily auto test does not complete, a report prints (if configured ON) and a momentary
message appears on the screen indicating the self test did not complete. In the event of an
incomplete daily auto test, confirm proper cable connection and perform the manual user test in
the OPTIONS menu. While attempting to perform the user test, if the message CONNECT TO
TEST PLUG appears, contact a qualified service representative.
If connected to AC power and the defibrillator detects a problem during the auto test, it remains
on and the service LED illuminates. If the defibrillator is not connected to AC power and the
defibrillator detects a problem during the auto test, the defibrillator will turn off after the auto test.
The service LED illuminates the next time the defibrillator is turned on. If the setup option for auto
print is on, a test report will automatically print at completion of the auto test. Refer to "General
Troubleshooting Tips," page 7-10.
Note: Integrity of the Standard Paddles and the QUIK-COMBO therapy cable is tested when
both the daily auto test is properly performed and section 8 on the Operator's Checklist is
completed (refer to Appendix D).
Note: The daily auto test cannot be relied on if REDI-PAK electrodes are connected to the
therapy cable. For daily testing, you must manually perform the user test in the Options menu
(refer to the User Test section).
Note: The factory setting for printed test reports is OFF. To obtain printed test reports, set the
self test to ON in the auto print menu (refer to the "Setup Options" section).

User Test
The LIFEPAK 20e defibrillator/monitor user test performs the same functions as the daily auto
test (refer to the "Daily Auto Test" section). The manual user test is recommended if the daily
auto test was not completed, if a test failure was reported, or if REDI-PAK electrodes are
preconnected to the therapy cable as part of defibrillator readiness. This test may also be
performed to meet more frequent defibrillator testing requirements.
To perform the user test, the standard paddles set must be securely seated in the paddle wells or
the QUIK-COMBO therapy cable must be connected to the QUIK-COMBO test plug (see
Figure 7-1). For REDI-PAK electrodes, disconnect the REDI-PAK electrodes from the
QUIK-COMBO therapy cable and connect the QUIK-COMBO test plug to the therapy cable.

Procedure:
1 Press ON.
Note: To perform the user test, ignore all REMOVE TEST PLUG prompts and keep the test
plug connected.
2 Press OPTIONS. If the defibrillator is in AED mode, switch to manual mode and then press
OPTIONS. Refer to "Switching from AED to Manual Mode," page 4-14.
3 Select USER TEST.
Note: If the message CONNECT TEST PLUG appears and the standard paddles set is
securely seated in the paddle wells or the QUIK-COMBO therapy cable is correctly
connected to the QUIK-COMBO test plug, contact a qualified service representative.
4 Select YES to initiate user test.
After selecting YES, the user test automatically performs the following tasks:
• Performs self-tests.
• Charges to a low energy level (approximately 1-3 joules) and then discharges through a test
plug or hard paddles.
• Tests the pacing circuitry (if noninvasive pacing installed).
• Prints the results.
• Turns itself off.
Note: During the user test, all front panel controls and standard paddles controls are
disabled. Pressing the ON button will power off the defibrillator.

LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Maintaining the Equipment
If the LIFEPAK 20e defibrillator/monitor detects a problem during the user test, the service LED
lights and a printed report indicates that the test failed. Turn off the defibrillator and contact
qualified service personnel. Refer to "General Troubleshooting Tips," page 7-10.
If it is necessary to interrupt the user test, turn the power off and then on again. The test will stop
and the defibrillator will operate normally. A Pass/Fail test report will not print.
Note: It is important to understand defibrillator operation. Refer to page 7-2 through
page 7-10 for suggested procedures to help ensure that personnel are acquainted with
normal defibrillator operation and to troubleshoot device performance. The procedures used
may vary according to your local protocols. To test the defibrillator by performing the function
checks requires the use of an optional test load simulator.
Cleaning
CAUTION!
7 Maintaining the Equipment
Possible equipment damage.
Do not clean any part of this device or accessories with bleach, bleach dilution, or phenolic
compounds. Do not use abrasive or flammable cleaning agents. Do not attempt to sterilize this
device or any accessories unless otherwise specified in accessory operating instructions.
Clean the LIFEPAK 20e defibrillator/monitor, cables, and accessories with a damp sponge or
cloth. Use only the cleaning agents listed below:
• Quaternary ammonium compounds
• Isopropyl alcohol
• Peracetic (peroxide) acid solutions
Clean the carrying case accessory as follows and as described on its instruction tag:
• Hand wash using mild soap or detergent and water. A scrub brush may be useful for heavily
soiled spots. Cleaners such as Formula 409® are helpful for grease, oil, and other tough
stains.
Function Checks
CAUTION!
Possible simulator damage.
Do not discharge more than 30 shocks within an hour or 10 shocks within a five-minute period,
or pace continually into Physio-Control patient simulators. Simulators may overheat.
The following function checks are provided to help personnel keep acquainted with normal
operating procedures and to troubleshoot device performance.
Older Physio-Control simulators and testers respond differently to defibrillators configured with a
biphasic defibrillation waveform. Older QUIK-COMBO simulators require a 275 joules biphasic
shock to change simulated VF rhythm to NSR. Sometimes no amount of energy can change the
simulated VF rhythm. The pace LED flashes when the shock does not change the simulated
rhythm.
Newer QUIK-COMBO simulators, described in the Physio-Control accessories catalog and on
the Web site, respond appropriately to defibrillators with a biphasic defibrillation waveform. For
further information, in the USA, call 1.800.442.1142. Outside the USA, contact your local
Physio-Control representative.

SETUP OPTIONS
Setup options allow you to define operating features for the LIFEPAK 20e defibrillator/monitor
such as device identification numbers and default settings. Table 8-1 through Table 8-21 list all
setup options along with the factory default settings.
Setup options can be selected in either of two ways:
• Use the Setup Options menu on the LIFEPAK 20e device. See "Entering Setup Options,"
page 8-3, for more information.
• Use LIFENET Device Agent to manage setup options on the LIFEPAK 20e device. See the
Help system for LIFENET Device Agent for more information.
WARNING!
Possible improper defibrillator performance.
Changing factory default settings will change the behavior of the device. Changes to the default
settings must only be made by authorized personnel.
Print Configurations Before Service or Repair
If the defibrillator receives service or repair that affects the internal memory components, such as
replacement of the main printed circuit board, any changes previously made to the option
definitions may be lost from memory. Before allowing service or repair, be sure to print the
current user setup defaults so the customized definitions may be reentered after service or
repair. (Refer to "Print Defaults," page 8-13.)
Passcode Security
To prevent unauthorized access, a security passcode is required for access to the Setup menu
and service mode (refer to page 8-14). The LIFEPAK 20e defibrillator/monitor allows you to
change both of these passcodes. The passcode definition is part of the device identification
option.
Note: To use the defibrillator with any new settings, you must turn the defibrillator off and on
again.
WARNING!
Possible ineffective energy delivery.
Service mode is for authorized personnel only. Improper use of service mode may inappropriately
alter the defibrillator’s configuration and may change energy output levels. Contact service
personnel for assistance or information about defibrillator configuration.

Respiration, Leads Off
Sensing, Noise Cancellation
Current, and Voltage
The ECG leads off function uses AC current for sensing leads
off, the disposable defibrillation electrodes use AC current for
leads off, and the ECG leads use a noise cancellation signal
which ranges from DC to approximately 5k Hz. The amplitude
of these signals conforms to AAMI EC-11 3.2.10 and AAMI
EC-13 (1992) 3.2.5.
Heart Rate Averaging
Method
The heart rate average is formed by a weighted average of
approximately 8 seconds duration. When the input rate is
trending rapidly, the rate meter will track more quickly. refer
to heart rate response time disclosure. The display update
interval is every heartbeat or every 2 seconds, whichever is
shorter.
Heart Rate With Irregular
Rhythm
All complexes are detected. The rate meter output can range
from the heart rate associated with the shortest R-R interval
to the heart rate associated with the longest R-R interval.
When present, intermediate length R-R intervals are favored
as the basis for the rate.
Heart Rate Alarm Time
In five trials for a 1 mV, 206 bpm tachycardia, the average
detection time was 7.1 seconds. The maximum detection
time was 7.9 seconds. The minimum time was 5.6 seconds.
For a test signal half as large, the average was 6.1 seconds,
the maximum was 6.4, and the minimum was 5.7. In this case
the device sensitivity was increased to 5 mV/cm.
For a test signal twice as large, the average was
5.7 seconds, the maximum was 6.3, and the minimum was
5.1.
In five trials for a 2 mV, 195 bpm tachycardia, the average
detection time was 6.2 seconds. The maximum detection
time was 7.1 seconds. The minimum time was 5.8 seconds.
For a test signal half as large, the average was 6.0 seconds,
the maximum was 6.7, and the minimum was 5.4. In this case
the device sensitivity was increased to 5 mV/cm.
For a test signal twice as large, the average was
6.0 seconds, the maximum was 6.4, and the minimum was
5.8.
Accuracy Of Signal
Reproduction
The device is a digital sampled data system. It meets

CHARACTERISTIC
Audible Alarms
This is a standalone device. All alarm tones are internal to the
biphasic LIFEPAK 20e defibrillator/monitor.
Alarm violations are manifest by tones, voice prompts, and
visual indications.
Alarm manifestation occurs within 1 second after a displayed
parameter violates its alarm limit. User selectable alarm
volume adjustment is provided. This adjustment does not
allow alarm volume to attain/reach a zero level.
SAS tones reinforce SAS messages provided on the product
display.
The following identifies the tone assignments for each type of
alarm:
• The priority 1 tone is used to alert the user to the possibility
of imminent death. This tone is a 440 Hz and 880 Hz
alternating tone with a 50% duty cycle and a 4 Hz
alternation frequency.
• The priority 2 tone is used to alert the user that a possible
life-threatening condition exists. This tone is a continuous
698 Hz tone.
• The priority 3 tone is used to alert the user that an abnormal
condition exists. Three beeps at 1046 Hz for 100 msec
duration each with a 150 msec silence between the first and
second and the second and third, followed by a 200 msec
silence.
• Priority 3 tones come in single and repeating types: for a
single tone, the 3-beep sequence sounds only once. For a
repeating tone, the 3-beep sequence sounds every 20
seconds.
• The priority 4 tone is a momentary tone between 500 and
1500 Hz. Specific characteristics are:
– QRS and Volume Setting Tone - 100 msec duration at
1397 Hz.
– Key click - 4 msec duration at 1319 Hz.
The alert tone shall consist of one set of two tones to precede
voice prompts and to draw attention to the display. Specific
characteristics shall be:
• 1000 Hz square wave, 100 msec duration.
• Silence, 100 msec duration.
• Silence, 140 msec duration (when preceding a voice
prompt).
• Voice prompt, when used.

LIFEPAK 20e Defibrillator/Monitor Operating Instructions
Specifications and Performance Characteristics
Visual Alarms
Alarms are indicated visually by:
The violated parameter flashes in inverse video with a
message in the status region of the display.
These visual indications remain on the display until the alarm
is corrected. Visual indication of alarms continue even when
the tones have been silenced.
Alarm Silencing
If a violated parameter alarms, the tone may be silenced for
two minutes by pressing the Alarms button.
A preemptive alarm silence is provided with selectable
settings of 2, 5, 10, and 15 minutes.
Visual alarms remain on at all times.
VF/VT Alarm
Automatically monitors the patient’s ECG rhythm for a
potentially shockable rhythm using the Continuous Patient
Surveillance System (CPSS). The VF/VT alarm requires that
the patient’s ECG be monitored in Lead II or Paddles lead
using therapy electrodes. The VF/VT alarm will be
suspended if pacing is enabled or Standard paddles are
connected and Paddles is the displayed lead.
Energy Shunting
If the paddles input is connected in parallel with a second
defibrillator, energy delivery to the patient is reduced by less
than 10 percent.
Tall T-wave Rejection
T-waves that are 1 mV high are not detected by the monitor
when the R-wave size is 1 mV and input rate is 80 ppm.
Displayed SpO2
The LIFEPAK 20e defibrillator/monitor is calibrated to display
functional saturation, which is the standard for SpO2.

DEFIBRILLATION OF VENTRICULAR FIBRILLATION AND VENTRICULAR
TACHYCARDIA
Background
Physio-Control conducted a multi-centered, prospective, randomized and blinded clinical trial of
biphasic truncated exponential (BTE) shocks and conventional monophasic damped sine wave
(MDS) shocks. Specifically, the equivalence of 200 J and 130 J BTE shocks to 200 J MDS
shocks1 was tested.
Methods
Results
Ventricular Fibrillation
The efficacy of the 200 J BTE shocks was demonstrated to be at least equivalent to the efficacy
of 200 J MDS shocks (95UCLD=2%). The difference in success rates of 200 J MDS minus 200 J
BTE shocks was -10% (exact 95% confidence interval from -27% to 4%). The 130 J BTE shocks
were not demonstrated equivalent to 200 J MDS shocks (95UCLD=22%). However, neither was
their efficacy significantly lower than that of the 200 J MDS shocks (statistical power limited by
small sample sizes). For all shock types, hemodynamic parameters (oxygen saturation and
systolic and diastolic blood pressure) were at or near their pre-induction levels by 30 seconds
after successful shocks.

Ventricular fibrillation (VF) was induced in 115 patients during evaluation of implantable
cardioverter defibrillator function and 39 patients during electrophysiologic evaluation of
ventricular arrhythmias. After 19±10 seconds of VF, a customized defibrillator delivered an
automatically randomized shock. Efficacy was based on success of this shock. To demonstrate
equivalence of test shocks to control shocks, the 95% upper confidence limit of the difference in
efficacy (95UCLD), control minus test, was required to be less than 10%.
Clinical Summaries
Ventricular Tachycardia
Seventy-two episodes of ventricular tachycardia (VT), induced in 62 patients, were treated with
randomized shocks. High rates of conversion were observed with biphasic and monophasic
shocks. Sample sizes were too small to statistically determine the relationship between success
rates of the waveforms tested.

Conclusions
In this double-blinded study, the efficacy of the 200 J BTE shocks was demonstrated to be at
least equivalent to the efficacy of 200 J MDS shocks for defibrillation of short duration,
electrically-induced VF. However, the comparison of efficacy of 130 J biphasic and 200 J
monophasic shocks for VF was inconclusive. All waveforms tested provided a high rate of
termination of VT. The VT sample sizes were too small to statistically determine the relationship
between VT success rates of the waveforms tested.
Compared to conventional shocks for VF, we found no positive or negative effect of biphasic
shocks for VF on hemodynamic parameters following the defibrillating shock. It is possible that,
compared to 200 J monophasic shocks, 200 J biphasic shocks will in some cases enable earlier
termination of VF. Therefore, we conclude that biphasic shocks for VF delivered at conventional
energy levels have the potential to improve outcome in resuscitation of patients with cardiac
arrest.

EXTERNAL CARDIOVERSION OF ATRIAL FIBRILLATION
Overview
The performance of the Physio-Control biphasic truncated exponential (BTE) waveform was
compared to the conventional monophasic damped sine (MDS) waveform in an international,
multi-center, prospective, randomized clinical study of adult patients undergoing elective
cardioversion of atrial fibrillation (AF). A total of 80 patients were enrolled in the study and were
treated with one or more study shocks. The primary dataset consisted of 72 enrolled patients
confirmed to have been in AF. Data from seven patients with atrial flutter were analyzed
separately. One patient who did not satisfy all protocol criteria was excluded from analysis.
This study showed that these biphasic shocks provide higher efficacy for cardioversion of atrial
fibrillation, requiring fewer shocks, 65% less current and 65% less energy to cardiovert atrial
fibrillation. Patients undergoing elective cardioversion with the biphasic protocol, as compared to
those receiving the monophasic protocol, reported significantly less post-procedure pain.
Objectives
The primary objective of the study was to compare the cumulative efficacy of biphasic and
monophasic shocks of 200 J or less for cardioversion of atrial fibrillation. A triangular sequential
design was used to test for a statistically significant difference between groups of patients treated
with these two waveforms.
Secondary objectives included 1) providing an estimation of the dose response relationship for
the two waveforms which would allow clinicians to make well-informed selections of energy
doses for cardioversion with biphasic shocks and 2) comparing the pain experienced by patients
following treatment with monophasic and biphasic shocks.
Results
Seventy-two of the patients enrolled were in atrial fibrillation and 7 were in atrial flutter. On
average, patients had been in atrial fibrillation for 88 days, were 66 years old, weighed 81 kg and
had 72 ohms of transthoracic impedance. Sixty-three percent were male and 46% had been
previously cardioverted. There were no significant differences between the groups of patients
treated with monophasic and biphasic shocks, either in these baseline characteristics or in left
atrial dimension, cardiac medications or diagnosis.
The cumulative success rates for cardioversion of atrial fibrillation are presented in Table B-1 and
Figure B-1. These data provide a reasonable estimate of the expected probability of cardioversion success for a single shock at any given energy level within the range studied. Energy
and peak current delivered for all shocks at each energy setting are presented in Table B-2.

Subjects were randomized to receive biphasic or monophasic shocks from LIFEPAK 12
defibrillator/monitors. Progressive shocks of 70, 100, 200 and 360 J of the assigned waveform,
and a 360 J crossover shock of the other waveform, were delivered if AF persisted. Shocks were
delivered using EDGE System QUIK-COMBO® Pacing/Defibrillation/ECG electrodes applied in
the standard anterior-lateral position. Successful cardioversion was defined as the confirmed
removal of AF after delivery of a shock, as determined by ECG over-read by two cardiologists
with no knowledge of the shock waveform. Patients rated skin pain on a scale from 0 to 8 after
the procedure.

Figure B-1 Cumulative Shock Success for Cardioversion of Atrial Fibrillation with Monophasic (MDS) and
Biphasic (BTE) Shocks: Observed Rates (n) Plotted with Estimated Dose Response Curves
Compared to monophasic shocks, biphasic shocks cardioverted atrial fibrillation with less peak
current (14.0 ± 4.3 vs. 39.5 ± 11.2 A, p<0.0001), less energy (97 ± 47 vs. 278 ± 120 J,
p<0.0001), fewer shocks (1.7 vs. 3.5 shocks, p < 0.0001) and less cumulative energy (146 ± 116
vs. 546 ± 265 J, p<0.0001). Patients treated with the biphasic protocol, as compared to those
treated with the monophasic protocol, reported significantly less post-procedure pain just after
(0.4 ± 0.9 vs. 2.5 ± 2.2, p<0.0001) and 24 hours after the procedure (0.2 ± 0.4 vs. 1.6 ± 2.0,
p<0.0001).
All patients with atrial flutter were cardioverted with the first shock (70 J), whether that shock was
monophasic (n=4) or biphasic (n=3).
Anterior-lateral electrode placement was used for treatment of most (96%) of the patients
studied. Reports in the literature differ on whether anterior-posterior electrode placement
provides better shock efficacy than anterior-lateral placement. If there is a benefit to anteriorposterior electrode placement, it may be possible to obtain modestly higher cardioversion
success rates with both waveforms than those observed in this study. However, placement is not
likely to affect the observed relationship between the efficacies of monophasic and biphasic
waveforms.
Conclusions
The data demonstrate the Physio-Control biphasic waveform is clinically superior to the
conventional monophasic damped sine waveform for cardioversion of atrial fibrillation.
Specifically, compared to monophasic shocks, biphasic shocks cardioverted atrial fibrillation with
less peak current, less energy, fewer shocks and less cumulative energy. Patients undergoing
elective cardioversion with the biphasic protocol, as compared to those receiving the monophasic
protocol, reported significantly less post-procedure pain just after and 24 hours after the
procedure. This may be due to fewer required shocks, less cumulative energy, less delivered
peak current or other characteristics of this biphasic waveform.

Clinical Summaries
Guidance for Selection of Shock Energy
Biphasic waveform technology is a standard in cardiac defibrillators. The study summarized here1
provides the best information available on which to base energy selections for cardioversion with this
waveform.
For cardioversion of atrial fibrillation, the results of this study provide specific guidance for
three possible strategies in selection of shock energy levels.
• To optimize for more rapid cardioversion and fewer shocks, select the same biphasic energy
levels used previously with monophasic defibrillators (e.g., use 200 J biphasic instead of 200 J
monophasic). This can be expected to increase the success rate yet decrease the peak
current of the first and subsequent shocks.
• To maintain shock efficacy equivalent to that previously observed with monophasic shocks,
select a biphasic energy level of about one-third the energy previously used for monophasic
shocks (e.g., use 100 J biphasic instead of 300 J monophasic).
• To optimize for low initial and cumulative energy using a step-up protocol, select 70 J for the
first shock and use small increases in energy if further shocks are needed.
Each of these strategies should provide effective cardioversion therapy while substantially
reducing the amount of peak current to which the heart is exposed.
For cardioversion of atrial arrhythmias other than atrial fibrillation, the data available to
guide the selection of energy settings is very limited. It is likely that biphasic doses below 50 J will
provide high success rates when treating atrial flutter and paroxysmal supraventricular
tachycardia. However, until more clinical data becomes available, it may be advisable to use the
same energy settings for biphasic shocks as are customarily used for monophasic shocks.
Arrhythmias may persist for a variety of reasons unrelated to the type of waveform used for
cardioversion. In persistent cases, clinicians continue to have the option to either increase shock
intensity or switch to an alternate electrode placement.

INTRA-OPERATIVE VENTRICULAR DEFIBRILLATION
Overview
The defibrillation efficacy of the Physio-Control biphasic truncated exponential (BTE) waveform
was compared to the standard monophasic damped sine waveform (MDS) in a prospective,
randomized multi-center study of patients undergoing intra-operative, direct defibrillation for
ventricular fibrillation (VF). A total of 251 adult patients were enrolled in the study; 98 of these
developed VF that was treated with one or more study shocks. Seven patients who did not
satisfy all protocol criteria were excluded from analysis.
Subjects were randomized to receive BTE or MDS shocks from LIFEPAK 12 defibrillator/monitor.
Those who developed VF after removal of the aortic clamp received progressively stronger
shocks of 2, 5, 7, 10 and 20 joules (J) using 2-inch paddles until defibrillation occurred. A 20 J
crossover shock of the alternate waveform was given if VF persisted.
Objectives
The primary objective of the study was to compare the cumulative efficacy of BTE shocks to
MDS shocks at 5 J or less. A triangular sequential design was used to test for a difference
between waveform groups.
The secondary objective was to provide an estimation of the dose response relationship for the
two waveforms that would allow physicians to make well-informed selections of energy doses for
intra-operative defibrillation with biphasic shocks.
Results
Thirty-five male and 15 female subjects were randomized to the BTE group; 34 and 7 to the MDS
group. Mean age was 66 and 68 years, respectively. There were no significant differences
between BTE and MDS treatment groups for cardiac etiology, arrhythmia history, current cardiac
medications, American Society of Anesthesiology (ASA) risk class, left ventricular wall thickness,
cardiopulmonary bypass time, core temperature or blood chemistry values at the time of aortic
clamp removal.
Cumulative defibrillation success at 5 J or less, the primary endpoint of the study, was
significantly higher in the BTE group than in the MDS group (p=0.011). Two of the 91 patients
included in this primary endpoint analysis could not be included in more comprehensive analyses
due to protocol variances that occurred in the shock sequence after the 5 J shock. Thus, the
cumulative success rates for intra-operative defibrillation in the remaining 89 patients are
presented in Table B-3 and Figure B-2. These data provide a reasonable estimate of the
expected probability of defibrillation success for a single shock at any given energy level within
the range studied.
Compared to the MDS group, the BTE group required, on average, fewer shocks (2.5 vs. 3.5:
p=0.002), less threshold energy (6.8 J vs. 11.0 J: p=0.003) and less cumulative energy (12.6 J
vs. 23.4 J: p=0.002). There was no significant difference between success rates for BTE versus
MDS crossover shocks.

The data demonstrate the Physio-Control biphasic waveform is clinically superior to the
conventional monophasic damped sine waveform for intra-operative internal defibrillation of VF.
Specifically, these biphasic shocks have higher defibrillation efficacy, while requiring fewer
shocks, less threshold energy and less cumulative energy than monophasic damped sine
shocks. There were no unsafe outcomes or adverse effects from the use of the biphasic
waveform.

Guidance for Selection of Shock Energy
Biphasic waveform technology is a standard in cardiac defibrillators. The results of this study1
provide specific guidance for three possible strategies in developing a dosing regimen.
• To optimize for lower initial and cumulative energy using a step-up protocol, select 5 J for the
first shock and use small incremental increases in energy if further shocks are needed. In this
study, biphasic shocks of 5 J were successful in approximately half of the patients.
• To optimize for more rapid defibrillation and fewer shocks, select the same BTE energy level
used previously with MDS (e.g., 20 J BTE instead of 20 J MDS), which can be expected to
increase the success rate yet decrease by approximately 30% the peak current of the first and
subsequent shocks.
• To maintain an equivalent degree of efficacy as previously observed with MDS shocks, a BTE
energy level one-half of that previously used for MDS shocks (e.g., 10 J BTE instead of 20 J
MDS) would be an appropriate choice.
Fibrillation may persist for a variety of reasons unrelated to the type of waveform used for
defibrillation. In cases where fibrillation is persistent, physicians continue to have the option to
either increase shock intensity or switch to a larger paddle size. Larger paddle size is known to
decrease energy requirements for successful defibrillation.2

Appendix E
SHOCK ADVISORY SYSTEM
Shock Advisory System
OVERVIEW OF THE SHOCK ADVISORY SYSTEM
The Shock Advisory System™ (SAS) is an ECG analysis system built into the LIFEPAK 20e
defibrillator/monitor that advises the operator as to whether it detects a shockable or
nonshockable rhythm. This system makes it possible for individuals who are not trained to
interpret ECG rhythms to provide potentially lifesaving therapy to victims of ventricular fibrillation
or pulseless ventricular tachycardia. The Shock Advisory System contains the following features:
• Electrode Contact Determination
• Automated Interpretation of the ECG
• Operator Control of Shock Therapy
• Continuous Patient Surveillance System (CPSS)
• Motion Detection
Electrode Contact Determination
The Shock Advisory System measures the patient's transthoracic impedance through the
therapy electrodes. If the baseline impedance is higher than a maximum limit, it determines that
the electrodes do not have sufficient contact with the patient or are not properly connected to the
AED. When this occurs, ECG analysis and shock delivery are inhibited. The AED advises the
operator to connect electrodes when there is insufficient electrode contact.
Automated Interpretation of the ECG
The Shock Advisory System recommends a shock if it detects the following:
• Ventricular fibrillation - with a peak-to-peak amplitude of at least 0.08 mV.
• Ventricular tachycardia - defined as having a heart rate of at least 120 beats per minute, QRS
width of at least 0.16 seconds, and no apparent P waves.
Pacemaker pulses may prevent advisement of an appropriate shock, regardless of the patient’s
underlying rhythm. The Shock Advisory System recommends no shock for all other ECG rhythms
including asystole, pulseless electrical activity, idioventricular rhythms, bradycardia,
supraventricular tachycardias, atrial fibrillation and flutter, heart block, premature ventricular
complexes and normal sinus rhythm. These rhythms are specifically mentioned in the AHA
recommendations.
Shock Advisory System Performance
ECG analysis by the Shock Advisory System (SAS) in the LIFEPAK 20e defibrillator/monitor
(AED) series was tested by playing ECG waveforms from the Physio-Control database through
the electrode connector. For each test ECG, the decision (shock or no shock) of the SAS was
recorded and compared to the rhythm classification and treatment recommendation by clinical
experts.
SAS Test Set
The SAS Test Set consists of 989 ECG samples recorded through defibrillation electrodes during
pre-hospital use of the LIFEPAK 5 defibrillators. The defibrillation electrodes and ECG signal
processing were similar to those used in the LIFEPAK 20e defibrillator/monitor. The ECG was
recorded using cassette tape recorders connected to the LIFEPAK 5 defibrillators. Selected ECG
segments were sampled and the ECG rhythm was classified by clinical experts. The rhythms

were selected to be a representative sample of rhythms seen during treatment of cardiac arrest.
The SAS Test Set contains the following ECG samples:
• 168 each coarse ventricular fibrillation (VF) (>= 200 µV peak-to-peak amplitude)
• 29 each fine ventricular fibrillation (< 200 and >= 80 µV peak-to-peak amplitude)
• 65 each shockable ventricular tachycardia (VT) (HR > 120 bpm, QRS duration >= 160 ms, no
apparent P waves, patient reported to be pulseless by the paramedics)
• 43 each asystole (< 80 µV peak-to-peak amplitude)
• 144 each normal sinus rhythm (NSR) (sinus rhythm, heart rate 60-100 bpm)
• 531 each other organized rhythm (includes all rhythms except those in other listed categories)
• 2 each transitional (transition occurs within the sample from nonshockable to nonshockable or
vice versa)
• 5 each shockable rhythms with pacemaker artifact (the pacemaker artifact is spread over time
by the filtering in the LIFEPAK 5 defibrillator)
• 2 each nonshockable rhythms with pacemaker artifact (the pacemaker artifact is spread over
time by the filtering in the LIFEPAK 5 defibrillator)

Shock Advisory System
Operator Control of Shock Therapy
The Shock Advisory System causes the AED to charge automatically when it detects the
presence of a shockable rhythm. When a shock is advised, the operator presses the SHOCK
button to deliver the energy to the patient. Analysis is disabled while the device is charging or
charged.
Continuous Patient Surveillance System
The Continuous Patient Surveillance System (CPSS) automatically monitors the patient's ECG
rhythm for a potentially shockable rhythm while the electrodes are attached and the AED is
turned on. CPSS is not active during ECG analysis or when the AED is in a CPR cycle.
Motion Detection
If medium-frequency variations in the transthoracic impedance signal exceed a maximum limit,
the Shock Advisory System determines that patient motion of some kind is present. If motion is
detected, the ECG analysis is delayed. The operator is advised by a displayed message, a voice
prompt, and an audible alert. After 10 seconds, if motion is still present, the motion alert stops
and the analysis always proceeds to completion. This limits the delay in therapy in situations
where it may not be possible to stop the motion. However, the rescuer should remove the source
of motion whenever possible to minimize the chance of artifact in the ECG.
Common causes of motion alerts include CPR, spontaneous patient movement, rescuers moving
the patient, and ambulance transport.
There are two reasons why ECG analysis is delayed when the motion alert occurs, and why the
rescuer should remove the source of the motion whenever possible:
1 Such motion may cause artifact in the ECG signal. This artifact can cause a nonshockable
ECG rhythm to look like a shockable rhythm. For example, chest compressions during
asystole can look like shockable ventricular tachycardia. Artifact can also cause a shockable
ECG rhythm to look like a nonshockable rhythm. For example, chest compressions during
ventricular fibrillation can look like an organized and, therefore, nonshockable rhythm.
2 The motion may be caused by a rescuer’s interventions. To reduce the risk of inadvertently
shocking a rescuer, the motion alert prompts the rescuer to move away from the patient. This
will stop the motion and ECG analysis will proceed.
The motion detection feature can be set to off. When this option is off, analysis of the ECG is
allowed to proceed uninhibited even in the presence of motion, which may or may not cause
artifact in the ECG as described previously. Artifact in the ECG can sometimes cause an
erroneous shock advisory decision.
The skill and training level of the care providers should be taken into consideration when
deciding whether or not to turn off the motion detection feature. How readily do the users
respond to the AED voice prompt? For example, do they immediately stop CPR upon hearing the
STAND CLEAR, ANALYZING NOW prompt?

About cprMAX Technology
ABOUT cprMAX TECHNOLOGY
Physio-Control cprMAX™ technology is designed to allow resuscitation protocols to maximize
the quantity of CPR administered during treatment with an AED, consistent with the 2005
American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency
Cardiovascular Care 1 (AHA Guidelines) and the European Resuscitation Council Guidelines for
Resuscitation 2005 2.
Setup options should be changed only under the direction of a physician knowledgeable in
cardiopulmonary resuscitation who is familiar with the literature in this area.
The cprMAX technology includes the following setup options:
• INITIAL CPR. Prompts the user to perform an initial period of CPR. Applies only to immediately
after turning on the AED or after the first analysis.
• PRESHOCK CPR time. Prompts for CPR after a shockable ECG rhythm is detected, before the
shock is delivered. If INITIAL CPR is set to OFF, then PRESHOCK CPR applies to all shock
advised decisions (including the first analysis).
• CPR TIME 1 and 2. CPR time periods after shocks or no shock advised decisions respectively.
• STACKED SHOCKS. Eliminates the analysis after each shock and inserts prompting for CPR
after each shock. This eliminates the three-shock stack.
• PULSE CHECK. Indicates when, if ever, the device is to prompt for pulse checks.
AED protocols are aligned with the AHA and ERC Guidelines when the setup options are set as
follows:
• Initial CPR: OFF
• PreShock CPR time: OFF
• CPR Times 1 & 2: 120 SECONDS
• Stacked Shocks: OFF
• Pulse Check: NEVER
The adult ventricular fibrillation (VF) energy label is also provided as the recommended energy
for treating VF 3 4. Refer to the label on your defibrillator for recommended doses.

receive training.
About cprMAX Technology
AED OPERATION WITH cprMAX TECHNOLOGY
The following paragraphs describe AED operation with cprMAX technology setup options.
Initial CPR
The INITIAL CPR option prompts the user to perform an initial period of CPR. The choices are:
OFF, ANALYZE FIRST and CPR FIRST. The factory default is OFF.
• The OFF setting has no prompting for an initial CPR period.
• The ANALYZE FIRST setting prompts for analysis and then CPR. If the analysis determines
that a shock is needed, the AED will prompt, IF YOU WITNESSED THE ARREST, PUSH
ANALYZE, which provides the opportunity to end CPR early and proceed directly to delivering
a shock.
• The CPR FIRST setting prompts the user to perform CPR immediately after the defibrillator is
powered on. The AED will also prompt, IF YOU WITNESSED THE ARREST, PUSH ANALYZE,
which provides the opportunity to end CPR early and proceed directly to analysis.
Hospitals that choose to implement this option should develop a protocol and provide training to
responders instructing them when to end the initial CPR interval early. Potential situations for
instructing responders to end CPR early include:
• The patient's collapse was witnessed by the responder.
• The responder ascertains that fewer than four or five minutes have elapsed since the patient's
collapse.
• The patient exhibits agonal breathing, an indicator of a short downtime.
• The responder ascertains that CPR of adequate quality and duration has already been
provided before attaching the AED electrodes.
Refer to Continuous Patient Surveillance System for a more detailed description of the AED
prompting sequence for each INITIAL CPR option.
Initial CPR Time
The INITIAL CPR TIME option applies when INITIAL CPR is set to ANALYZE FIRST or CPR FIRST. It
sets the CPR time for that CPR period. The time choices for INITIAL CPR TIME are: 15, 30, 45, 60,
90, 120, and 180 SECONDS. The default setting is 120 SECONDS.
PreShock CPR Time
The PRESHOCK CPR time option inserts prompting for CPR when a shockable ECG rhythm is
detected and during the time the AED is charging. It applies only when analysis results in SHOCK
ADVISED decisions. When INITIAL CPR is set to OFF or CPR FIRST, PRESHOCK CPR time applies
to the first and all subsequent shocks. When INITIAL CPR is set to ANALYZE FIRST, PRESHOCK
CPR time apples to the second and all subsequent shocks. The choices for PRESHOCK CPR time
are: OFF, 15, and 30 SECONDS. To prompt for CPR only for the time the capacitor is charging,
select the 15-seconds CPR interval. The SHOCK button is not enabled until charging and CPR
time are completed. The default setting for PRESHOCK CPR time is OFF.
Note: Although the SHOCK button is disabled during the PRESHOCK CPR interval, it becomes
active as soon as the PRESHOCK CPR interval ends. To minimize the interval between the
final chest compression and shock delivery (while maintaining responder safety), hospital
protocols that select this option should provide specific training and protocols to address the
rapid transition from PRESHOCK CPR to shock delivery.
F-2
LIFEPAK 20e Defibrillator/Monitor Operating Instructions
About cprMAX Technology
Stacked Shocks
When set to OFF, the STACKED SHOCKS option inserts prompting for CPR after each (a single)
shock. This eliminates the three-shock stack. CPR is prompted after the shock regardless of the
ECG rhythm. The CPR time following the shock is determined by the CPR TIME 1 setting
selected. Choices for the STACKED SHOCKS option are ON or OFF. The default setting is OFF.
When this option is set to ON, the defibrillator follows the previously traditional stacked shock
protocol and delivers up to three consecutive shocks, as necessary, without interposed CPR.
Pulse Check
The PULSE CHECK option inserts prompting to check for a pulse or check the patient, depending
on the PULSE PROMPT setting. The choices for PULSE CHECKS are: ALWAYS, AFTER EVERY
NSA, AFTER SECOND NSA, and NEVER. The default setting is NEVER.
• The ALWAYS option prompts for a pulse check after CPR Times 1 and 2, after a NO SHOCK
ADVISED decision, after a single SHOCK ADVISED decision with STACKED SHOCKS OFF, or
after three consecutive SHOCK ADVISED decisions if STACKED SHOCKS is ON.
• The AFTER EVERY NSA option prompts for a pulse check after every NO SHOCK ADVISED
decision.
• The AFTER SECOND NSA option prompts for a pulse check after the second analysis if the
second analysis results in a NO SHOCK ADVISED decision, regardless of the first analysis
decision (SHOCK ADVISED or NO SHOCK ADVISED).
• The NEVER option eliminates all PULSE CHECK prompts.

Where P is the maximum output power rating of
the transmitter in watts (w) according to the
transmitter manufacturer and d is the
recommended separation distance in meters (m).2
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,3
should be less than the compliance level in each
frequency range.4
Interference may occur in the vicinity of equipment
marked with the following symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
1. The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to
13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
2. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are
intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently
brought into patient areas. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for
transmitters in these frequency ranges.
3. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitter, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the LIFEPAK 20e defibrillator/monitor is used exceeds the applicable RF compliance level above, the LIFEPAK 20e
defibrillator/monitor should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the LIFEPAK 20e defibrillator/monitor.
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

Recommended Separation Distances between Portable and Mobile RF Communications
Equipment and the LIFEPAK 20e Defibrillator/Monitor Series
The LIFEPAK 20e defibrillator/monitor is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the LIFEPAK 20e defibrillator/monitor can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the LIFEPAK 20e defibrillator/monitor as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
meters (m) can be determined using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to
6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
Note 3: An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters
in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5
GHz to decrease the likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas.
Note 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
