Safety Information
<
WARNING:
While the ventilator is in use, an alternative means of ventilation should always be available in the event of a ventilator problem. This is particularly true for ventilator-dependent patients. Supplementary observation, appropriate for the patient's condition, is also recommended.
<
WARNING:
To ensure that ventilation continues uninterrupted, ensure alternative power sources are available (AC power source, extra batteries, or an auxiliary DC car adapter). Be prepared for the possibility of power failure by having an alternative means of ventilation ready for use – particularly for ventilatordependent patients.
<
WARNING:
Do not allow a patient to remain connected to the ventilator when ventilation is stopped, because a substantial quantity of exhalation gas, primarily carbon dioxide, may be inhaled by the patient. In some circumstances, inhaling carbon dioxide may lead to under-ventilation, suffocation, and serious injury or death.
<
WARNING:
Always have immediate access to an alternative means of ventilation, which is ready for use, to avoid patient death or serious injury.
<
WARNING:
The ventilator must not be used with flammable anesthetic substances.
<
WARNING:
Do not start ventilation until you ensure that the device is suitably assembled, that the air inlet filter is properly installed and is not obstructed, and that there is proper clearance all around the unit. Also ensure that the patient circuit is suitably connected to both the ventilator and the patient and that the patient circuit, including all hoses, is not damaged or obstructed.

Clinician's Manual
Device Classification
2.3.1
Safety Net
Incorporated in the ventilator design is an alarm system that continuously monitors both patient and machine for signs of specific errors or faults that could lead to an unsafe condition. Should any of these errors or faults be detected, the alarm system announces the specific alarm condition both audibly and visually. The machine-related alarm conditions are factory set, whereas the patientrelated alarm conditions are defined by alarm-threshold values selected by an operator (a clinician or a caregiver). For more information, see Chapter
5 , Alarms and Troubleshooting .
2.3.2
Settings
A software key, known as the Locking key, restricts access to ventilation parameter settings and ventilation mode changes in order to distinguish between clinician usage and patient usage (see
Locking the Control Panel on page 7-35 ).
2.3.3
Oxygen Enrichment
Oxygen may be supplied from an external, low pressure source, but the oxygen flow must be limited to 15 lpm (50 kPa, 500 mbar). The ventilator automatically compensates for the extra flow created by the external oxygen supply (see Chapter
,
).
2.3.4
Breathing Circuit
The ventilator can be used with a single- or double-limb patient circuit. If exhaled volume monitoring is required (such as ventilator dependent patients), use the double-limb circuit for exhaled tidal volume monitoring. For more information, see
on page
<
WARNING:
Users must always possess an additional breathing circuit and exhalation valve while using the Puritan
Bennett™ 560 ventilator.

3 Operating Parameters
3.1
Overview
This chapter describes ventilation and alarm parameters and their setting ranges for each ventilation mode. For a listing of operating parameters and monitored patient data, see Table
ed by the Puritan Bennett™ 560 ventilator, see Appendix
<
WARNING:
The ventilator offers a variety of breath delivery options. Throughout the patient’s treatment, the clinician should carefully select the ventilation mode and settings to use for that patient, based on clinical judgment, the condition and needs of the patient, and the benefits, limitations, and characteristics of the breath delivery options. As the patient’s condition changes over time, periodically assess the chosen modes and settings to determine whether those are best for the patient’s current needs.
<
WARNING:
Setting any alarm limits to OFF or extreme high or low values can cause the associated alarm not to activate during ventilation, which reduces its efficacy for monitoring the patient and alerting the clinician to situations that may require intervention.
<
WARNING:
If Apnea Time is set to a value higher than 60/Rate then the Apnea alarm will not activate.
<
WARNING:
The Min PIP alarm setting must be adjusted for the patient, but must also be set high enough to allow
the Patient Disconnection alarm to trigger properly. Perform the low pressure test (see section F.1
Low Pressure Test ) to ensure that the alarm is properly set.
<
WARNING:
The Max Leak alarm setting must be adjusted for the patient, but must also be set low enough to allow the High Leakage alarm to trigger properly. Perform the max leak test (refer to section
(NIV).

3.2.1
P Support—Pressure Support
When Relative pressure is set to YES in the Setup menu, P Support allows you to determine inspiratory pressure added to PEEP during the inspiratory phase.
In this configuration, the sum of P Support and PEEP must not exceed 55 mbar.
When Relative pressure is set to OFF in the Setup menu, P Support allows you to determine inspiratory absolute pressure.
In this configuration, P Support and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
3.2.2
PEEP—Positive End Expiratory Pressure
PEEP allows you to determine the level of pressure maintained during the exhalation phase.
When Relative pressure is set to YES in the Setup menu, the sum of P Support and PEEP must not exceed 55 mbar.
Clinician's Manual 3-3
3-4
Operating Parameters
When relative pressure is set to OFF, P Support and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
The ventilation mode can be adjusted without PEEP (PEEP is nearly 0 mbar when set to OFF) in valve configuration.
In leak configuration, the minimum PEEP setting is 4 mbar.
3.2.3
Rise Time
•
•
•
This parameter is used during the inspiration phase to determine how the target pressure will be reached. This setting indirectly defines the minimum inspiratory time.
•
The different levels available are as follows:
Rise time 1 = 200 ms
Rise time 2 = 400 ms
Rise time 3 = 600 ms
Rise time 4 = 800 ms
These time ranges are determined by the pressure setting required, the breath rate, and the physiological condition of the patient.
3.2.4
I Sens—Inspiratory Trigger Sensitivity
I Sens allows you to set the level of inspiratory effort the patient has to provide during the initiation of a machine breath.
The sensitivity levels are 0P, 1P, 2, 3, 4, and 5 (P denotes pediatric use); the lower the number, the more sensitive the trigger sensitivity.
I Sens can be set to OFF.
<
WARNING:
Ensure that the I Sens setting is not set to OFF when ventilating patients capable of triggering spontaneous breaths.
<
WARNING:
Carefully modify the trigger threshold setting to reduce the risk of ventilator autotriggering. Level 0P, the most sensitive inspiratory trigger, is recommended for pediatric use. For an adult, this setting may result in ventilator autotriggering.
Clinician's Manual
PSV Mode Parameters and Setting Ranges
3.2.5
E Sens—Exhalation Sensitivity
E Sens is available in the PSIMV, VSIMV, and PSV modes.
E Sens allows you to determine sensitivity of switching to exhalation and thus indirectly determines the inspiratory time of a breath.
The end of inspiration will occur when inspiratory flow has decreased to the preset E Sens setting.
The exhalation trigger is only taken into account after the Rise Time (which constitutes a default minimum inspiratory time) has elapsed.
If the flow drop is insufficient, exhalation is automatically triggered independently of the E Sens, which is defined as a percentage of peak inspiratory flow. Exhalation may be triggered if the maximum inspiratory time has elapsed. For more information about maximum inspiratory time, see section
, Min and Max I Time—Minimum and Maximum Inspiration Time .
Figure 3-3. Exhalation Trigger Sensitivity y2 Exhalation x Seconds y1 Inspiration
:
Note:
See section
, Changing the Setup Menu Parameters
for positive and negative E Sens settings.
3.2.6
Backup R—Backup Rate
Backup R allows you to determine the frequency of ventilation breaths to be applied in the event of prolonged apnea – as long as no inspiratory trigger is detected.
The inspiratory time of the backup breaths applied in the event of apnea still depends on the detection of exhalation trigger (E Sens) and the safety maximum inspiratory time (see above comment on E Sens). The rise time of these cycles is identical to the ventilation cycle previously set.
The controlled cycles following apnea are interrupted as soon as a new spontaneous inspiration of the patient is detected.
Clinician's Manual 3-5
Operating Parameters
The Backup R is linked to the Min I Time so that the Min I Time setting cannot be greater than half the inspiratory phase of a ventilator-controlled breath.
Backup R breath is delivered at the Pressure Support settings.
Setting a backup rate is not optional; it is always set.
3.2.7
Apnea Time
Apnea time allows the user to monitor and detect interruptions to the patient's spontaneous breathing pattern. The ventilator declares apnea when no breath has been delivered by the time that the operator-selected apnea interval elapses.
The Apnea time adjustment range shall be 1 to 60 seconds. The ventilator shall enable the operator to set an auto-setting. The Apnea time AUTO setting (in seconds) is calculated using the formula
(Auto = maximum value between 3 seconds and 60/Backup R or AUTO=30 in CPAP mode).
:
Note:
During apnea ventilation, the ventilator delivers machine controlled breaths according to a backup rate (Backup
R)—as long as no inspiratory trigger has been detected.
:
Note:
The Backup R value applied depends on the Rate setting.
:
Note:
If the Apnea alarm is set to OFF in the Preferences menu, the Apnea time setting will still be active.
3.2.8
Vt Target—Target Tidal Volume
Vt Target allows the ventilator to deliver a target volume of gas to the patient.
When a Vt Target is set, the ventilator constantly adjusts the target inspiratory pressure between Pi and Max P to ensure the inspired tidal volume remains as close as possible to the Vt target.
Vt Target should be more than 10 ml higher than Min VTE and more than 10 ml lower than Max VTI to avoid triggering VTI or VTE alarms.
The minimum increase or decrease of target inspiratory pressure is 0.5 mbar and the maximum is 2 mbar.
Setting the Vt Target is not mandatory (it can be set to OFF).
3-6
3.2.9
Max P—Maximum Inspiration Pressure
Max P allows the ventilator to adjust the inspiratory pressure up to a maximum limit in order to reach the target tidal volume (Vt Target).
P Support and Max P are related and the difference between them must be less than 20 mbar.
Max P is not shown when Vt Target is set to OFF.
Clinician's Manual
PSV Mode Parameters and Setting Ranges
3.2.10
Min and Max I Time—Minimum and Maximum Inspiration Time
Min I Time and Max I Time are ventilation parameters that can be adjusted in the alarm menu.
Min I Time defines the minimum duration of time the inspiratory phase is maintained. It takes priority over activation of the exhalation trigger which can only be triggered after the Min I Time has expired.
The Backup R is linked to the Min I Time so that the Min I Time setting cannot be greater than half the inspiratory phase of a cycle triggered by the ventilator.
If Backup R is changed, Min I Time is, if necessary, automatically readjusted so that the difference between them is always maintained.
The minimum time by default if no parameter is set (Min I Time = AUTO) corresponds to the Rise
Time to which an operating margin of 0.3 seconds is added. See
for details about Rise Time.
Max I Time defines the maximum duration of time during which the inspiratory phase is maintained.
The switch-over to exhalation occurs, at the latest, after this time has expired.
By default, if no parameter is set, the maximum time (Max I Time = AUTO) is the shortest time between a fixed time of 3 seconds and half the duration of the patient’s inspiratory breaths expressed in seconds. (AUTO equals the lesser of 3 seconds or 30/Rate). This default value will be applied if it is lower than the Max I Time setting.
Min I Time and Max I Time are related so that the Max I Time cannot be set to a value lower than the
Min I Time.
3.2.11
Min and Max VTI—Minimum and Maximum Inspiratory Tidal Volume
It is possible to set a minimum, maximum, or both Tidal Volume alarm threshold for the patient’s inspired tidal volume during a cycle.
This setting is used to trigger an alarm if the tidal volume inspired by the patient is lower than the minimum threshold set (Low VTI alarm) or greater than the maximum threshold set (High VTI alarm).
See Chapter
,
Min VTI and Max VTI are related, and their settings must be set to values that maintain a minimum difference of 20 ml between the two.
It is not mandatory to set the minimum and maximum VTI alarm limits. When the minimum and maximum VTI alarm limits are not set, the display will show “OFF” next to these settings.
3.2.12
Min and Max VTE—Minimum and Maximum Exhalation Tidal Volume
Use a double-limb patient circuit configuration when setting the minimum, maximum, or both
Exhalation Tidal Volume alarm parameters.
Clinician's Manual 3-7
Operating Parameters
These thresholds can be set to trigger an alarm if the tidal volume expired by the patient is lower than the minimum threshold set (Low VTE alarm) or greater than the maximum threshold set (High
VTE alarm). See Chapter
5 , Alarms and Troubleshooting

Pi—Inspiratory Pressure
When Relative pressure is set to YES in the Setup menu, Pi allows you to determine inspiratory pressure added to PEEP during the inspiratory phase.
In this configuration, the sum of Pi and PEEP must not exceed 55 mbar.
When Relative pressure is set to OFF in the Setup menu, Pi allows you to determine inspiratory absolute pressure.
In this configuration, Pi and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
Clinician's Manual 3-13
Operating Parameters
3.4.2
PEEP—Positive End Expiratory Pressure
PEEP allows you to determine the level of pressure maintained during the exhalation phase.
When Relative pressure is set to YES in the Setup menu, the sum of Pi and PEEP must not exceed 55 mbar.
When relative pressure is set to OFF, Pi and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
The ventilation mode can be adjusted without PEEP (PEEP is nearly 0 mbar when set to OFF) in valve configuration.
In leak configuration, the minimum PEEP setting is 4 mbar.
3.4.3
Rise Time
•
•
•
•
•
•
This parameter is used during the inspiration phase to adjust how the pressure setpoint will be reached. This setting indirectly defines the minimum inspiratory time.
•
The different levels available are as follows:
Rise time 1 = 200 ms
Rise time 2 = 400 ms
Rise time 3 = 600 ms
Rise time 4 = 800 ms
These time ranges are determined by the combination of the pressure setting required, the breath rate and the physiological conditions of the patient.
•
The pressure rise time built-up at each cycle depends on the inspiratory time corresponding to the combination of the rate setting and the Insp Time setting.
Rise Time 1 is always possible
Rise Time 2 is established only if Insp Time ≥0.7 seconds
Rise Time 3 is established only if Insp Time ≥0.9 seconds
Rise Time 4 is established only if Insp Time ≥1.1 seconds
3.4.4
Rate—Respiratory Rate
Rate allows you to define the minimal frequency of mandatory ventilator breaths.
If the patient actuates the inspiration trigger, total Rate may increase.
3-14 Clinician's Manual
P A/C Mode Parameters and Setting Ranges
3.4.5
Insp Time—Inspiratory Time
This parameter allows the user to set the inspiratory time to 0.3-6.0 s. When changing Insp Time, the ventilator shows the corresponding I:E ratio or I/T% in the settings window. The maximum I:E setting is constrained to 1:1.
3.4.6
I Sens—Inspiratory Trigger Sensitivity
I Sens allows you to set the level of inspiratory effort the patient has to provide to initiate a machine breath.
The sensitivity levels are 0P, 1P, 2, 3, 4, and 5 (P denotes pediatric use); the lower the number, the more sensitive the trigger sensitivity.
I Sens can be set to OFF.
<
WARNING:
The inspiration trigger threshold should be carefully modified in order to avoid the risk of false triggering or “autotriggering” of the ventilator. For example, Level 0P, the most sensitive mode, is recommended for pediatric use. However, for an adult, this setting may result in autotriggering.
3.4.7
Vt Target—Target Tidal Volume
Vt Target allows the ventilator to deliver a target volume of air to the patient.
When a Vt Target is set, the ventilator constantly adjusts the target inspiratory pressure between Pi and Max P to ensure the inspired tidal volume remains as close as possible to the Vt target.
Vt Target should be more than 10 ml higher than Min VTE and more than 10 ml lower than Max VTI to avoid triggering VTI or VTE alarms.
The minimum increase or decrease of target inspiratory pressure is 0.5 mbar and the maximum is 2 mbar.
Setting the Vt Target is not mandatory (it can be set to OFF).
3.4.8
Max P—Maximum Inspiration Pressure
Max P allows the ventilator to adjust the inspiratory pressure up to a maximum limit in order to reach the target tidal volume (Vt Target).
Pi and Max P are related and the difference between them must be less than 20 mbar.
Max P is not shown when Vt Target is set to OFF.
Clinician's Manual 3-15
Operating Parameters
3.4.9
Min and Max VTI—Minimum and Maximum Inspiratory Tidal Volume
It is possible to set a Min, Max, or both Tidal Volume alarm threshold for the patient’s inspired tidal volume during a cycle.
This setting is used to trigger an alarm if the tidal volume inspired by the patient is lower than the minimum threshold set (Low VTI alarm), or greater than the maximum threshold set (High VTI alarm). See Chapter
5 , Alarms and Troubleshooting .
Min VTI and Max VTI are related and their settings must be set to values that maintain a minimum difference of 20 ml between the two.
It is not mandatory to set the minimum and maximum VTI alarm limits. When the minimum and maximum VTI alarm limits are not set, the display will show “OFF” next to these settings.
3.4.10
Min and Max VTE—Minimum and Maximum Exhalation Tidal Volume
A Min, Max, or both Tidal Volume Expired by the patient alarm threshold can always be set but can only be used in a double-limb circuit configuration.
These thresholds can be set to trigger an alarm if the tidal volume expired by the patient is lower than the minimum threshold set (Low VTE alarm) or greater than the maximum threshold set (High
VTE alarm). See Chapter
5 , Alarms and Troubleshooting
.
Min VTE and Max VTE are related and their settings must be set to values that maintain a minimum difference of 20 ml between the two.
VTE is shown when ventilating with an exhalation valve.
Setting Min VTE and Max VTE is not mandatory (they can be set to OFF), but the display of the measured value is always active in double-limb configuration.
3.4.11
Max Leak—Maximum Leakage
The setting of a high leakage threshold enables a High Leakage alarm to be triggered in the event the calculated leakage flow exceeds this limit. The displayed value corresponds to the mean parasite leakage flow observed during the exhalation phase.
3.4.12
Max Rtot—Maximum Total Breath Rate
The maximum rate threshold setting is used to warn of hyperventilation or autotriggering of the ventilator. This setting is used to trigger the High Rate alarm. See Chapter
,
The Max Rtot threshold must always be set at least 5 bpm higher than the Rate. If the Rate is readjusted, the Max Rtot is automatically readjusted to maintain a minimum difference of 5 bpm.

Vt—Tidal Volume
Vt allows you to set the tidal volume to be delivered to the patient at each inspiratory phase.
For physiological and safety reasons, the Vt setting is limited by the settings of Insp Time and Rate.
The ratio of Vt to Insp Time (Vt / Insp Time) is [3 < (Vt × 60) / (Insp Time × 1000) < 100].
<
WARNING:
Ensure that the patient circuit is appropriate for the tidal volume setting (tube Ø 22 mm for adults, and
Ø 15 mm for pediatric tidal volumes lower than 200 ml).
3.5.2
PEEP—Positive End Expiratory Pressure
PEEP allows you to determine the level of pressure maintained during the exhalation phase.
The ventilation mode can be adjusted without PEEP (PEEP is nearly 0 mbar when set to OFF).
3-18 Clinician's Manual
V A/C Mode Parameters and Setting Ranges
3.5.3
Ramp Pattern—Flow Shape
•
•
This parameter is used to adjust the flow distribution shape (or ramp pattern) during the inspiratory phase.
•
The three flow patterns available are:
Ramp Pattern SQ: Square waveform or constant flow
Ramp Pattern D: Decelerated (sawtooth waveform) or decreasing flow
Ramp Pattern S: Sinusoidal flow
3.5.4
Rate—Respiratory Rate
Rate allows you to define the frequency of ventilation cycles triggered by the ventilator.
If the patient actuates the inspiratory trigger, total Rate may increase.
For physiological and efficiency reasons, Rate setting is limited by the settings of Vt and I:E (I/T).
3.5.5
Insp Time—Inspiratory Time
This parameter allows the user to set the inspiratory time to 0.3-6.0 s. When changing Insp Time, the ventilator shows the corresponding I:E ratio or I/T% in the settings window. The maximum I:E setting is constrained to 1:1.
3.5.6
I Sens—Inspiratory Trigger Sensitivity
I Sens allows you to set the level of inspiratory effort the patient has to provide to initiate a machine breath.
The sensitivity levels are 0P, 1P, 2, 3, 4, and 5 (P denotes pediatric use); the lower the number, the more sensitive the trigger sensitivity.
I Sens can be set to OFF.
<
WARNING:
The inspiration trigger threshold should be carefully modified in order to avoid the risk of false triggering or “autotriggering” of the ventilator. For example, Level 0P, the most sensitive mode, is recommended for pediatric use. However, for an adult, this setting may result in autotriggering.
3.5.7
Sigh Vt
A sigh is an increased volume of gas delivered to the patient at a set rate (that is, every 50 breaths).
The Vt multiplied by Sigh Vt gives the amount of volume delivered to the patient during a Sigh.
Clinician's Manual 3-19
Operating Parameters
3.5.8
Sigh Rate
Sigh Rate is the frequency with which sigh breaths are delivered.
3.5.9
Min and Max PIP—Minimum and Maximum Peak Inspiratory Pressure
A minimum and maximum inspiratory pressure alarm threshold must be set.
The Min PIP (or Low Pressure) setting determines the trigger threshold for the Patient Disconnection alarm. See Chapter
5 , Alarms and Troubleshooting . If this pressure level is not reached during a
fixed time, the alarm is triggered.
<
WARNING:
The Low PIP alarm setting must be adjusted for the patient, but must also be set high enough to allow
on page
F-2 ) to ensure that the Low PIP alarm is properly set.
The Max PIP or Max Pressure setting determines the level of pressure which is not to be exceeded during the inspiratory phase. Once this level is reached, inspiration is terminated, ventilation switch-
es to exhalation, and a High PIP alarm is triggered. See Chapter 5 , Alarms and Troubleshooting
.
The difference between the Min PIP and Max PIP settings is limited to a minimum of 8 mbar.
This setting is also limited by the setting of PEEP; thus, the Min PIP setting must exceed the PEEP setting by at least 2 mbar. In addition, the Max PIP setting must exceed the PEEP setting by at least
10 mbar. A change in the PEEP level may lead to automatic changes in the Min PIP, Max PIP, or both thresholds, in order to maintain these setting differences.
3.5.10
Min and Max VTE—Minimum and Maximum Exhalation Tidal Volume
Minimum, maximum, or both exhalation tidal volume settings are adjustable, but can only be used with a double-limb circuit configuration.
These thresholds can be set to trigger an alarm if the tidal volume expired by the patient is lower than the minimum threshold set (Low VTE alarm) or greater than the maximum threshold set (High
VTE alarm). See Chapter
5 , Alarms and Troubleshooting
.
Min VTE and Max VTE are linked to Vt so that Vt must be greater than Min VTE by at least 10 ml but lower than Max VTE by at least 10 ml.
If Vt is changed, Min VTE and Max VTE are automatically readjusted so that the difference between them is always maintained.
VTE is shown when ventilating with an exhalation valve.
Setting Min VTE and Max VTE is not mandatory (they can be set to OFF, which is the default setting), but the measured value is always shown when using double-limb configurations.

When Relative pressure is set to YES in the Setup menu, P Support allows you to determine inspiratory pressure added to PEEP during the inspiratory phase of spontaneous breaths.
In this configuration, the sum of P Support and PEEP must not exceed 55 mbar.
When Relative pressure is set to OFF in the Setup menu, P Support allows you to determine inspiratory absolute pressure of spontaneous breaths.
In this configuration, P Support and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
3.6.3
PEEP—Positive End Expiratory Pressure
PEEP allows you to determine the level of pressure maintained during the exhalation phase.
When Relative pressure is set to YES in the Setup menu, the sum of Pi or P Support and PEEP must not exceed 55 mbar.
When Relative pressure is set to OFF, Pi or P Support and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
The ventilation mode can be adjusted without PEEP (PEEP is nearly 0 mbar when set to OFF) in valve configuration.
In leak configuration, the minimum PEEP setting is 4 mbar.
3.6.4
Rate—Respiratory Rate
R-Rate is the rate at which the ventilator control pressure cycles are initiated, excluding apnea phases.
Rate and Insp Time are related so that if Rate is greater than 12 bpm, then Insp Time must be between 20% and 80% of the breath cycle duration as determined by Rate:
Insp Time <0.33 × 60 /R Rate if Rate ≥8.
Insp Time ≤2.4 if Rate <8.
:
Note:
During apnea ventilation, the ventilator delivers controlled breaths according to a backup rate (Backup R) as long as no inspiratory trigger has been detected.
:
Note:
The Backup R value applied depends on the Rate setting. Hence, Backup R is at least equal to 8 bpm and is equal to the Rate value if Rate is greater than 8 bpm.
Clinician's Manual 3-23
Operating Parameters
3.6.5
Insp Time—Inspiratory Time
Insp Time allows you to determine the inspiratory phase duration of ventilator-controlled breaths.
For physiological and efficiency reasons, its setting is limited by those of Vt and Rate. The maximum
I:E ratio is constrained to 1:2.
Backup R and Insp Time are related.
3.6.6
I Sens—Inspiratory Trigger Sensitivity
I Sens allows you to set the level of inspiratory effort the patient has to provide to initiate a machine breath.
The sensitivity levels are 0P, 1P, 2, 3, 4, and 5 (P denotes pediatric use); the lower the number, the more sensitive the trigger sensitivity.
I Sens can be set to OFF.
<
WARNING:
The inspiration trigger threshold should be carefully modified in order to avoid the risk of false triggering or “autotriggering” of the ventilator. For example, Level 0P, the most sensitive mode, is recommended for pediatric use. However, for an adult, this setting may result in autotriggering.
3.6.7
Apnea Time
Apnea time allows the user to monitor and detect interruptions to the patient's spontaneous breathing pattern. The ventilator declares apnea when no breath has been delivered by the time that the operator-selected apnea interval elapses.
The Apnea time adjustment range shall be 1 to 60 seconds. The ventilator shall enable the operator to set an auto-setting. The Apnea time AUTO setting (in seconds) is calculated using the formula
(Auto = maximum value between 3 seconds and 60/Backup R or Auto = 30 if Backup R = OFF).
:
Note:
During apnea ventilation, the ventilator delivers machine controlled breaths according to a backup rate (Backup
R)—as long as no inspiratory trigger has been detected.
:
Note:
The Backup R value applied depends on the Rate setting. Hence, Backup R is at least equal to 8 bpm and takes the Rate value if Rate is greater than 8 bpm.
3.6.8
Min and Max I Time—Minimum and Maximum Inspiration Time
The minimum (Min I Time) and maximum (Max I Time) duration of the inspiratory phase cannot be set in V SIMV or P SIMV mode. In both the V SIMV and P SIMV modes, the Min I Time defaults to a setting equal to RISE TIME + 300 ms and the Max I Time defaults to the lesser of 3 seconds or 30/Rate.
3-24 Clinician's Manual
P SIMV Mode Parameters and Setting Ranges
3.6.9
Rise Time
The Rise Time during the inspiratory phase can be set in P SIMV mode and the range is 1-5. The device is configured with a default Rise Time setting of 2 (or a pressure rise time of 200 ms to 800 ms).
3.6.10
E Sens—Exhalation Sensitivity
E sens is available in the P SIMV, V SIMV, and PSV modes. In CPAP, E Sens is defaulted to 25% and is not adjustable.
E Sens allows you to determine sensitivity of switching to exhalation and thus indirectly determines the inspiratory time of a breath.
The end of inspiration will occur when Inspiratory Flow has decreased to the preset E Sens setting.
The exhalation trigger is only taken into account after the Rise Time (which constitutes a default minimum inspiratory time) has elapsed.
If the flow drop is insufficient, exhalation is automatically triggered independently of the E Sens, which is defined as a percentage of peak inspiratory flow. Exhalation may be triggered if the maximum inspiratory time has elapsed. For more information about maximum inspiratory time, see section
,

Min and Max VTI—Minimum and Maximum Inspiratory Tidal Volume
It is possible to set a Min, Max, or both Tidal Volume alarm threshold for the patient’s inspired tidal volume.
This setting is used to trigger an alarm if the tidal volume inspired by the patient is lower than the minimum threshold set (Low VTI alarm) or greater than the maximum threshold set (High VTI alarm).
See Chapter
5 , Alarms and Troubleshooting .
Min VTI and Max VTI are related and their setting must maintain a minimum difference of 20 ml between them.
It is not mandatory to set the minimum and maximum VTI alarm limits. When the minimum and maximum VTI alarm limits are not set, the display will show “OFF” next to these settings.
3.6.12
Min and Max VTE—Minimum and Maximum Exhalation Tidal Volume
A Min, Max, or both Tidal Volume Expired by the patient alarm threshold can be set but can only be used in a double-limb circuit configuration.
These thresholds can be set to trigger an alarm if the tidal volume expired by the patient is lower than the minimum threshold set (Low VTE alarm) or greater than the maximum threshold set (High
VTE alarm). See Chapter
5 , Alarms and Troubleshooting
.
Min VTE and Max VTE are related and their settings must be set to values that maintain a minimum difference of 20 ml between them.
VTE is shown when ventilating with an exhalation valve.
Setting Min VTE and Max VTE is not mandatory (set to OFF), but the display of the measured value is always active in double-limb configuration.
3.6.13
Max Rtot—Maximum Total Breath Rate
The maximum rate threshold set monitors the risk of hyperventilation or ventilator autotriggering.
Its setting is used to trigger the High Rate alarm. See Chapter
5 , Alarms and Troubleshooting .
When set, the Max Rtot threshold must always exceed the Rate setting by at least 5 bpm. If the Rate is readjusted, the Max Rtot is automatically readjusted to maintain a minimum difference of 5 bpm.
Setting the Max Rtot is not mandatory (it can be set to OFF, the default setting), but the measured value is always shown.

Vt—Tidal Volume
Vt allows you to set the tidal volume delivered to the patient at each inspiration phase of intermittent or successive controlled breath cycles (triggered by the ventilator) in the event of patient apnea.
For physiological and safety reasons, the Vt setting is limited by the settings of Insp Time and Rate.
The ratio of Vt to Insp Time (Vt / Insp Time) must be:
3 lpm <(Vt × 60) / (60/Rate × I/T) Insp Time × 1000) <100 lpm.
<
WARNING:
Ensure that the patient circuit is appropriate for the tidal volume setting (tube Ø 22 mm for adults, and
Ø 15 mm for pediatric tidal volumes lower than 200 ml).
:
Note:
The Backup R value applied depends on the Rate setting. Hence, Backup R is at least equal to 8 bpm and takes the Rate value if Rate is greater than 8 bpm.

P Support—Pressure Support
When Relative pressure is set to YES in the Setup menu, P Support allows you to determine inspiratory pressure added to PEEP during the inspiratory phase of spontaneous breaths.
In this configuration, the sum of P Support and PEEP must not exceed 55 mbar.
When Relative pressure is set to OFF in the Setup menu, P Support allows you to determine inspiratory absolute pressure of spontaneous breaths.
In this configuration, P Support and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
3.7.3
PEEP—Positive End Expiratory Pressure
PEEP allows you to determine the level of pressure maintained during the exhalation phase.
When Relative pressure is set to YES in the Setup menu, the sum of P Support and PEEP must not exceed 55 mbar.
When relative pressure is set to OFF, P Support and PEEP are related and their settings must maintain a minimum difference between the two of 2 mbar in leak configuration and 5 mbar in valve configuration.
The ventilation mode can be adjusted without PEEP (PEEP is nearly 0 mbar when set to OFF) in valve configuration.
In leak configuration, the minimum PEEP setting is 4 mbar.
3.7.4
Rate—Respiratory Rate
Rate is the rate at which ventilator-controlled breaths are triggered, excluding apnea ventilation.
Rate and Insp Time are related so that if Rate is greater than 8 bpm, then Insp Time must be:
0.2 × 60 / Rate <Insp Time <0.8 × 60 / Rate.
:
Note:
During apnea ventilation, the ventilator delivers controlled breaths according to a backup rate (Backup R) as long as no inspiratory trigger has been detected.
:
Note:
The Backup R value depends on the Rate setting. Hence, Backup R is at least equal to 8 bpm and becomes equal to the Rate value if Rate is greater than 8 bpm.

Insp Time —Inspiratory Time
Insp Time allows you to determine the inspiratory phase duration of ventilator-controlled breaths.
For physiological and efficiency reasons, its setting is limited by those of Vt and Rate. The maximum
I:E Ratio is constrained to 1:2.
The ratio Vt/Insp Time must be between 3 liters and 100 liters [3 <(Vt × 60) / (InspTime × 1000)
<100].
:
Note:
The Backup R value depends on the Rate setting. Hence, Backup R is at least equal to 8 bpm and becomes equal to the Rate value if Rate is greater than 8 bpm.
3.7.6
I Sens—Inspiratory Trigger Sensitivity
I Sens allows you to set the level of inspiratory effort the patient has to provide during the initiation of a machine breath.
The sensitivity levels are 0P, 1P, 2, 3, 4, and 5 (P denotes pediatric use); the lower the number, the more sensitive the trigger sensitivity.
<
WARNING:
The inspiration trigger threshold should be carefully modified in order to avoid the risk of false triggering or “autotriggering” of the ventilator. For example, Level 0P, the most sensitive mode, is recommended for pediatric use. However, for an adult, this setting may result in autotriggering.

Apnea time allows the user to monitor and detect interruptions to the patient's spontaneous breathing pattern. The ventilator declares apnea when no breath has been delivered by the time that the operator-selected apnea interval elapses.
The Apnea time adjustment range shall be 1 to 60 seconds. The ventilator shall enable the operator to set an auto-setting which shall automatically calculate the Apnea time according to the following: Apnea Time = 60 / BACKUP R for PSV ST mode or 12 s for V SIMV and P SIMV modes.
The Apnea time “AUTO” setting (in seconds) is calculated using the formula (Auto = Maximum value between 3 seconds and 60/Backup R or Auto = 30 if Backup R = OFF).
:
Note:
During apnea ventilation, the ventilator delivers machine controlled breaths according to a backup rate (Backup
R)—as long as no inspiratory trigger has been detected.

Min and Max I Time—Minimum and Maximum Inspiration Time
The minimum (Min I Time) and maximum (Max I Time) duration of the inspiratory phase cannot be set in V SIMV or P SIMV mode. In both the V SIMV and P SIMV modes, the Min I Time defaults to a setting equal to RISE TIME + 300 ms and the Max I Time defaults to the lesser of 3 seconds or 30/Rate.
3.7.9
Ramp
The distribution shape (or flow pattern) of the flow rate during the inspiratory phase cannot be set in V SIMV mode. The device is configured by default with a square wave flow pattern that represents a constant flow rate.
3.7.10
Rise Time
The Rise Time during the inspiratory phase can be set in V SIMV mode and the range is 1-5. The ventilator has a default Rise Time of 2 (or a pressure rise time of 400 ms).
3.7.11
E Sens—Exhalation Sensitivity
E Sens is available in the P SIMV, V SIMV, and PSV mode. E Sens allows you to determine sensitivity of switching to exhalation and thus indirectly determines the inspiratory time of a breath.
The end of inspiration will occur when inspiratory flow has decreased to the preset E Sens setting.
The exhalation trigger is only taken into account after the Rise Time (which constitutes a default minimum inspiratory time) has elapsed.
If the flow drop is insufficient, exhalation is automatically triggered independently of the E Sens, which is defined as a percentage of peak inspiratory flow. Exhalation may be triggered if the maximum inspiratory time has elapsed. For more information about maximum inspiratory time, see section

Min and Max PIP—Minimum and Maximum Peak Inspiratory Pressure
A minimum and maximum pressure alarm threshold must be set.
The Min PIP (or Min Pressure) setting determines the trigger threshold for the Patient Disconnection alarm. See Chapter
5 , Alarms and Troubleshooting .
<
WARNING:
The setting of the Low PIP alarm must be adjusted for the patient, but must also be set high enough to allow the Patient Disconnection alarm to trigger properly. Perform the low pressure test (refer to
Pressure Test on page F-2 ) to ensure the Low PIP alarm is properly set.
The Max PIP or Max Pressure setting determines the level of pressure which is not to be exceeded during the inspiratory phase. When this level is reached, inspiration is terminated, the device switch-
es to exhalation, and a High PIP alarm is triggered. See Chapter 5 , Alarms and Troubleshooting
.
The difference between the Min PIP and Max PIP settings is limited to a minimum of 8 mbar. Their settings are also limited by that of PEEP; thus, Min PIP must be greater than PEEP by at least 2 mbar and Max PIP must be greater than PEEP by at least 10 mbar. A change in the PEEP level may lead to automatic changes in the Min PIP, Max PIP, or both thresholds so that these differences are always maintained.
3.7.13
Min and Max VTI—Minimum and Maximum Inspiratory Tidal Volume
It is possible to set a Min and/or Max alarm threshold for the inspired tidal volume received by the patient.
VTI allows you to trigger an alarm during breath delivery if the tidal volume inspired by the patient is lower than the minimum threshold set (Low VTI alarm) or greater than the maximum threshold set (High VTI alarm). See Chapter
,
Clinician's Manual
V SIMV Mode Parameters and Setting Ranges
Min VTI and Max VTI are related to Vt such that Vt must be higher than Min VTI by at least 10 ml, but lower than Max VTI by at least 10 ml.
If Vt is changed, Min VTI and Max VTI are, if necessary, automatically readjusted so that the difference between them is maintained.
Setting Min VTI and Max VTI is not mandatory (set to OFF), but the display of the measured value is always active in a double-limb configuration.

Ventilation Report
The Ventilation Report is available in the Preferences menu (see Chapter 7 , Operating Procedures ).
The Ventilation Report updates daily at 8 AM and shows the average readings from the previous 24 hours. See
Figure 4-15. Ventilation Report

Note:
The values shown in the Ventilation Report are reinitialized when the software is updated or the patient counter is reset to 0.
Clinician's Manual 4-9
Monitored Parameters
The following data is shown in the Ventilation Report:
Vent Time — The ventilation duration data is based on the patient counter and shows the total ventilation time in hours and minutes over the previous 24-hour period.
VTI — When ventilating with an exhalation valve, the VTI is the average inspired tidal volume during each ventilation cycle over the previous 24-hour period. When ventilating in leak mode, the VTI is the average volume delivered by the ventilator during each ventilation cycle over the previous 24-hour period.
VTE — When ventilating with a double-limb circuit configuration and an exhalation valve, the VTE is the average exhaled volume during each ventilation cycle over the previous 24-hour period. In a single-limb circuit configuration this value is not measured.
Paw — The peak airway pressure is the average peak pressure during the inspiratory phase, measured by each cycle and over the previous 24-hour period.
Rate — The respiratory rate is the average of the total respiratory frequency of the patient and the ventilator measured over the previous 24-hour period.
Leak — When ventilating with a leak configuration circuit, it is the average parasitic leak during each cycle and over the past 24-hour period. When ventilating with a single-limb circuit there is no average leak.
AI — The apnea index is the average number of apnea events per hour of ventilation. It is based on the
Apnea alarm.
Apnea Ti — Accumulated apnea time over the previous 24-hour period.
Spont Cyc — This is the percentage of ventilation cycles initiated by the patient and the ventilator over the previous 24-hour period.
Machine — Total time in hours that the ventilator has been switched on since manufacture.
Patient — Total time in hours and minutes that the current patient has been ventilated.

5 Alarms and Troubleshooting
5.1
Overview
•
•
The alarms or faults generated by the Puritan Bennett™ 560 ventilator are classified into two categories:
Ventilation (or utilization) alarms
Technical faults
Alarms indicate events likely to affect the ventilation in the short term and necessitate rapid inter-
on page
).
Some of the ventilator alarms are adjustable, depending on ventilation modes (see Chapter 3 ,
Operating Parameters ). Automatic, nonadjustable alarms also exist to create a safety net for safer
patient ventilation.
Technical faults do not directly affect machine operation. Therefore, the user is not alerted to technical faults. Only authorized and trained technicians may consult the Maintenance menu (see the service manual).
<
WARNING:
Setting any alarm limits to OFF or extreme high or low values can cause the associated alarm not to activate during ventilation, which reduces its efficacy for monitoring the patient and alerting the clinician to situations that may require intervention.
<
WARNING:
When an alarm condition is triggered, or there is evidence of a patient-ventilator fault or problem, examine the patient first before examining the ventilator.
<
WARNING:
Do not pause, disable, or decrease the volume of the ventilator’s audible alarm if patient safety could be compromised.
:
Note:
Default alarm setting preferences should be entered prior to using the ventilator.

Alarms and Troubleshooting
:
Note:
All configurable alarm settings are recorded in the ventilator’s nonvolatile internal memory, and are retained when powering down or in the event of a total loss of power.
5.2
Alarm Level of Priority
•
•
•
The alarm hierarchy for signaling the level of alarm criticality is listed as follows:
Very high priority (VHP): Immediate critical situation; ventilation is impossible: Continuous sound signaling / with or without continuous red LED illumination / with or without message / with or without display lighting (it is possible for an alarm condition to occur that may not have both a message and lighting)
High priority (HP): Critical situation in the short term; ventilation is potentially compromised: High speed intermittent sound signaling / flashing red LED illumination / with message / with display lighting
Medium priority (MP): Critical situation in the long term; ventilation is not affected in the short term:
Medium speed intermittent sound signaling / flashing yellow LED illumination / with message / with display lighting
• Low priority (LP): Ventilation is not affected in the short term, but potential for delayed minor injury or discomfort: Medium speed intermittent sound signaling / continuous yellow LED illumination / with message / with display lighting
:
Note:
If there is no corrective action and if the audible alarm is not inhibited (Audio Paused) or reset (Alarm Reset) within 60 seconds, high priority alarms will sound at the maximum level.
5.3
Alarm Display
:
Note:
The alarm indicator LEDs to the left of the ALARM CONTROL key on the Puritan Bennett™ 560 ventilator are designed to be visible to the operator at any position where the ventilator is visible to the operator. Specific alarm detail (shown in the alarm message area) is designed to be readable from up to four meters from the screen, at a viewing angle of up to 30°.
The ventilator is constructed to meet the compliance requirements of the IEC 60601-1-8 alarm standard.
•
During operation, when an alarm is activated, the following events occur:
One of the red or yellow alarm indicators to the left of the ALARM CONTROL key illuminates and possibly flashes.
• An alarm tone sounds.
A message is shown and flashes in reverse video at the bottom of the Ventilation menu or Alarm menu.

If this is not possible, it is best to modify the patient disconnection triggering threshold by doing one of the following: Set a Max VTI alarm limit for pressure modes, or a Min VTE alarm limit for all ventilation modes if using a dual limb circuit.
:
Note:
Ensure that the length and the internal volume of the patient circuit are compatible with the tidal volume:
Ringed tube Ø 22 mm for adults and ringed tube Ø 15 mm for pediatric patients with tidal volumes lower than
200 ml. Use, if necessary, a 22F-15M link on the outlet and a 15M-22M link on the exhalation block for a doublelimb circuit.
<
WARNING:
When using non-invasive ventilation (NIV), without an exhalation valve, use a vented nose or face mask or a non vented combined with a leak accessory. When using non-invasive ventilation (NIV), with an exhalation valve, use a non vented mask.
<
WARNING:
The level of inspiratory resistance of the circuit and accessories (bacteria filter, humidifier, and so on) must be as low as possible. Settings—particularly the Patient Disconnection alarm, high inspired volume (High VTI), and low inspired volume (Low VTI) settings—must be periodically adjusted according to changes in the patient circuit resistance—especially when filters are replaced.
<
WARNING:
Resistance of the exhalation valve and accessories (water traps, filters, HMEs, etc.) must be as low as possible.
<
WARNING:
The exhalation valve must allow rapid discharge of the circuit pressure. Ensure that the exhalation valve is always clean and its evacuation aperture (exhaust port) is never obstructed.
<
WARNING:

Filters
<
WARNING:
Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. If necessary, replace the filter before the recommended replacement period is over (see Chapter
). This is particularly important when the ventilator is installed on a wheelchair, because environmental conditions may cause the filter to become dirty more rapidly.
•
The ventilator features two filter types:
Air inlet filter
Bacteria filter •
6.5.1
Air Inlet Filter
Consisting of foam and fine particle filter media and located at the rear of the ventilator, this filters the air as it enters the ventilator.
Figure 6-13. Air Inlet Filter
<
WARNING:
The air inlet filter is not reusable; do not attempt to wash, clean, or reuse it.
<
WARNING:
Failing to replace a dirty air inlet filter, or operating the ventilator without a filter, may cause serious damage to the ventilator.
Clinician's Manual 6-17
Installation and Assembly
6.5.2
Bacteria Filter
It is highly recommended that you install a bacteria filter (see Figure
) on both single- and double-limb circuits.
Figure 6-14. Bacteria Filter
•
A single-limb configuration uses one bacteria filter, at the TO PATIENT port. A double-limb configuration uses two bacteria filters, one at the TO PATIENT port, and the other at the FROM PATIENT port.
Connected to the TO PATIENT port: The filter protects the ventilator from contamination by the patient
(primarily, rebreathed gas). See Figure 6-7
(item 1), Figure
connected here, the filter is called the inspiratory bacteria filter.
• Connected to the FROM PATIENT port: The filter protects the internal exhalation flow sensor from the gases exhaled by the patient. See Figure
6-9 (item 11). When connected here (using a circuit adapter),
the filter is called the exhalation bacteria filter.
See the manufacturer’s instructions for more information about the use and maintenance of bacteria filters.
6.6
Humidifier
The humidifier (Figure
6-15 ) adds moisture (water vapor) and warms the gas in the patient circuit. It
is inserted into the patient circuit between the TO PATIENT outlet port and the patient (see Figures
,
, and
).
Figure 6-15. Humidifier
6-18 Clinician's Manual
Humidifier
<
WARNING:
During invasive ventilation (when an artificial airway bypasses the patient’s upper respiratory system), the patient’s upper respiratory system cannot humidify the incoming gas. For this reason, the use of a humidifier, to minimize drying of the patient’s airways and subsequent irritation and discomfort, must be used.
<
WARNING:
Always position a humidification device so that it is lower than both the ventilator and the patient. Use water traps, if necessary, to limit water in the patient circuit and periodically empty these water traps.
Take precautions when discarding the fluid in the water trap. Discard per local ordinance for proper disposal.
<
WARNING:
If a heated humidifier is used, you should always monitor the temperature of the gas delivered to the patient. Gas delivered from the ventilator that becomes too hot may burn the patient's airway.
<
WARNING:
Adding accessories to the ventilator breathing circuit, such as a humidifier and water trap(s), may result in a decrease in tidal volume delivered to the patient due to the added compressible volume of the accessory. Always assure that the patient is receiving the appropriate inspired volume when altering the breathing circuit configuration.
When a humidification device is used, any condensation that forms in the patient circuit is collected in the water trap (or traps). If you notice any moisture in the patient circuit, you need to replace the wet circuit components with dry ones.
See the humidification device’s instructions for information on operating, cleaning, and sterilizing the humidifier.

WARNING:
The Puritan Bennett™ 560 ventilator can be used with an optional oxygen analyzer with minimum and maximum concentration alarms. Always measure the delivered oxygen with a calibrated oxygen analyzer (FiO
2
kit) that features a minimum and maximum concentration alarm in order to ensure that the prescribed oxygen concentration is delivered to the patient.
Oxygen administered to the patient is introduced from an external source into the machine through the oxygen connector at the rear of the ventilator. It is then integrated into the total volume of delivered gas. Remove the oxygen inlet connector from the back of the ventilator when external oxygen is not in use.
The specific oxygen flow to the patient depends on the physiological characteristics of the patient and the ventilator settings.
The oxygen flow setting should be adjusted for each patient and established in relation to a calibrated oxygen monitor measurement. As the factors that affect administered oxygen flow may change over time, you must ensure that these settings always correspond to the current oxygen therapy objectives specified by the physician.

1 Nurse call cable connector 2 Nurse call cable receptacle
To connect the nurse call cable (see Figure 6-27 ):
1.
Align the key feature on the nurse call cable connector (item 1) with the corresponding key feature in the nurse call cable receptacle on the rear of the ventilator (item 2).
2.
Push the connector into the receptacle, taking care not to bend the connector pins.
:
Note:
The Puritan Bennett™ 560 ventilator has been designed to accommodate connectivity with nurse call/ monitoring systems. Because it is not possible to anticipate every configuration of hardware and software associated with nurse call/monitoring system, it is the user’s responsibility to confirm proper functionality of the system when used in conjunction with the ventilator. Verification of alarms, alerts, and patient data transmissions is required. If the system performance is not as expected, contact Technical Support for assistance troubleshooting the setup. Do not use the Puritan Bennett™ 560 ventilator with a nurse call/monitoring system until the functionality of the ventilator/system combination has been confirmed.
Clinician's Manual
Connecting the Nurse Call Cable
:
Note:
Complete a self-test after the cable has been installed and at regular intervals to ensure the system is operating as intended. A self-test consists of inducing an alarm and confirming the nurse call/monitoring system unit emits an audio alarm, and also confirming the audio alarm ceases once the alarm in the ventilator has been reset.
•
The nurse call function provides for remote alerts of ventilator alarm conditions (for example, when the ventilator is used in an isolation room), and features the following:
The ventilator signals an alarm using a normally open (NO) or a normally closed (NC) signal.
•
• A remote alarm is activated when an alarm condition occurs, unless either of the following is true:
– The audio paused function is active.
– The ventilator power switch is OFF.
The alarm delay, once generated from the ventilator, to the nurse call output/input cable connectors is less than 100 ms.
The remote alarm port is an eight-pin female connector; allowable current is 100 mA at 24 VDC (max).

Turning on the Ventilator
<
WARNING:
Before operating the ventilator, read, understand, and strictly follow the information contained in
Chapter 1 , Safety Information .
<
WARNING:
If the ventilator has been transported or stored at a temperature that differs more than ±20°C (±36°F) from the temperature in which it will be operating, the ventilator should be allowed to stabilize in its operating environment for at least 2 hours prior to use.
<
WARNING:
To reduce the risk of a fire hazard, keep matches, lighted cigarettes, and all other sources of ignition
(such as flammable anesthetics and/or heaters) away from the ventilator and oxygen hoses.
<
WARNING:
While the ventilator is in use, an alternative means of ventilation should always be available in the event of a ventilator problem. This is particularly true for ventilator-dependent patients.
Supplementary observation, appropriate for the patient's condition, is also recommended.
<
WARNING:
To ensure that ventilation continues uninterrupted, ensure alternative power sources are available
(AC power source, extra batteries, or an auxiliary DC car adapter). Be prepared for the possibility of power failure by having an alternative means of ventilation ready for use—particularly for ventilatordependent patients.
<
WARNING:
Do not start ventilation until you ensure that the device is suitably assembled, that the air inlet filter is properly installed and is not obstructed, and that there is proper clearance all around the unit. Also ensure that the patient circuit is suitably connected to both the ventilator and the patient and that the patient circuit, including all hoses, is not damaged or obstructed.
<
WARNING:
The time required to reach essential performance and start ventilation from power on is approximately 15 seconds.
7-1
7-2
Operating Procedures
<
WARNING:
Users must always possess an additional breathing circuit and exhalation valve while using the Puritan
Bennett™ 560 ventilator.
<
WARNING:
Verify the functionality of the alarms before connecting the patient to the ventilator. Refer to Appendix
<
WARNING:
Before starting ventilation, always verify that all settings are properly set in accordance with the required prescription.
<
WARNING:
The ventilator offers a variety of breath delivery options. Throughout the patient’s treatment, the clinician should carefully select the ventilation mode and settings to use for that patient, based on clinical judgment, the condition and needs of the patient, and the benefits, limitations, and characteristics of the breath delivery options. As the patient’s condition changes over time, periodically assess the chosen modes and settings to determine whether those are best for the patient’s current needs.
<
WARNING:
If the ventilator fails the alarm tests or if you cannot complete the tests, refer to section
or call your equipment supplier or Covidien.
<
WARNING:
Due to the internal battery’s limited reserve capacity, the ventilator should only be operated on the internal battery when no other power source is available. Ensure that the internal battery never becomes fully discharged.
To turn the ventilator on, set the I/O (power) switch (a covered, rocker-type switch located at the rear of the ventilator) to the I position, as shown in

E Sens Setting
Back
Cycling Mode
The cycling mode is used to set which calculated value (I:E or I/T) appears in the parameter zoom window when changing Insp Time or Rate settings. It is also used to set the monitored data value
(I:E or I/T) shown in the monitored data window and graphics screen.
The two cycling modes represent the relationship between inspiration time to exhalation time as follows:
1.
I/T is inspiratory time (Ti) as a percentage of total breath cycle time (Ti + Te).
I/T (%) = [Ti / (Ti+Te)] ×100
2.
I:E is the ratio of inspiratory time (Ti) to exhalation time (Te).
I:E = 1/(Te /Ti)
In P A/C and V A/C modes, the cycling ratio changes based on patient inspiration; however, the inspiratory time remains constant and corresponds to the rate and cycling ratio settings.
Clinician's Manual
Setup Menu Parameters
:
Note:
When adjusting I:E or I/T ratio, the corresponding calculated Ti is displayed below the parameter zoom in the monitoring and information window.
Absolute and Relative Pressure
The relative pressure for the inspiratory pressure setting (P Control and P Support) in PSV, P A/C, and
P SIMV, can be set to OFF or YES and allows the choice between setting the inspiratory pressure relative to PEEP or setting an absolute inspiratory pressure. The default value is absolute (ABS).
If relative pressure is set to YES, the PEEP is added to the inspiratory pressure setting to determine the peak inspiratory pressure. If relative pressure is set to OFF, the inspiratory pressure setting will determine the peak inspiratory pressure regardless of the PEEP setting.
Relative pressure = YES: Inspiratory pressure setting + PEEP = Peak inspiratory pressure
Relative pressure = OFF (ABS): Inspiratory pressure setting = Peak inspiratory pressure
The symbol ABS for absolute or REL for relative will be shown at the top of the screen as follows:
Figure 7-14. Absolute and Relative Pressure
E Sens Settings
E Sens enables the operator to adjust the sensitivity of the expiratory trigger in Pressure Support breaths in PSV, P SIMV and V SIMV modes which will cycle the breath into the expiratory phase.
During a Pressure Support inspiration the delivered flow will reach a peak value and then begin to decelerate toward zero. The E Sens setting allows the operator to set the flow value, as a percentage of peak flow, that will cycle the breath to exhalation.The E Sens setting can be set to either POSITIVE or NEGATIVE.
If set to POSITIVE, E Sens is based on the percentage of inspiratory peak flow. If set to NEGATIVE, E
Sens is based on the percentage of inspiratory peak flow by which the flow must decrease before exhalation is declared.

The settings of the next mode (shown as INACTIVE on the screen) can be “prepared” while ventilation is in progress in the current mode (shown as ACTIVE on the screen). The modifications will be saved for this next mode, whether or not it is used immediately afterwards.
Clinician's Manual
Setting Ventilation Parameters
When setting the parameters of the currently inactive mode, the monitoring data for the mode in progress are shown in the window to the right of the menu and also in the central (Current) column of the table on the Alarm menu screen.
When changing the value of a parameter in the inactive mode, the monitoring data displayed in the window on the right side of the screen are temporarily hidden by the display of the value currently being changed. This is shown in the following figure, as the I Sens setting is adjusted in the inactive
V A/C mode.
Figure 7-29. Changing Ventilation Modes During Ventilation (4)
If an alarm is triggered during the setting of an inactive mode, its message is shown in the alarm message area.
When the menu of an inactive mode is shown and no changes are made by the user on the keyboard within 14 seconds, the active ventilation mode in use reappears on the screen and the Accept
Mode: YES line disappears.
The menu of the active mode can also be recalled without waiting for this delay by directly restoring the name of the mode on the general information line.
The ventilation parameters of the inactive mode and the current mode remain in memory until some or all of the parameters are modified again; this is true even after the machine is stopped.

Reduce PEEP so that the P Support setting can be set higher than 35 to ensure that their sum is no greater than 55.
7.5.2
Links Between Ventilation and Alarm Parameters
Setting a ventilation parameter takes priority over an alarm threshold setting and leads to automatic readjustment of the alarm setting threshold so that the interdependence between the two remains unchanged.
Once the ventilator is in service at the patient’s home, you should use the Locking key to block
access to changing any settings (see Locking the Control Panel on page 7-35

If a parameter change is not confirmed by pressing ENTER before 7 seconds elapse, the ventilator resets the parameter to its previous value.
7.6.1
Blocking an Alarm Threshold Linked to a Ventilation Parameter
•
•
Setting a ventilation parameter takes priority over an alarm threshold setting. Therefore, if a ventilation parameter is modified when linked to an alarm threshold, the alarm setting threshold is automatically adjusted so that the interdependences linking them are always maintained.
However, if the alarm setting threshold is modified, it cannot be changed beyond the limit of the interdependence with the ventilation parameter to which it is linked. When the alarm setting limit is reached, the message “Setting limited by...” indicates the name of the linked ventilation parameter(s) that are limiting the parameter’s setting value.
•
Four possibilities exist in this case:
The alarm parameter remains set to OFF.
The alarm parameter setting is changed in relation to the value required at the start and the limits on the ventilation parameter (parameters) remain unchanged.
The setting of the ventilation parameter (or parameters) is changed to enable the alarm threshold to be set to the required value.
• The alarm parameter is not set to OFF but the ventilation parameter change has no impact on the alarm setting.
<
WARNING:
The level of inspiratory resistance of the circuit and accessories (bacteria filter, humidifier) must be as low as possible. Settings—particularly the Patient Disconnection alarm, maximum inspired volume
(Max VTI), and minimum inspired volume (Min VTI) settings—must be periodically adjusted according to changes in the patient circuit resistance—especially when filters are replaced.

8 Internal Battery
<
WARNING:
Even though the Puritan Bennett™ 560 ventilator meets current safety standards, the internal
Lithium-ion battery of the device exceeds the 100Wh threshold and is therefore considered to be
Dangerous Goods (DG) Class 9 – Miscellaneous, when transported in commerce. As such, the Puritan
Bennett™ 560 ventilator and/or the associated Lithium-ion battery are subject to strict transport conditions under the Dangerous Goods Regulation for air transport (IATA: International Air Transport
Association), International Maritime Dangerous Goods code for sea and the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) for Europe. Private individuals who transport the device are excluded from these regulations although for air transport some requirements apply. For air transport; the Puritan Bennett™ 560 ventilator is permitted as checked-in or carry-on baggage. Two spare batteries per person may be taken on board as carry-on luggage only, with the prior approval of the airline. This classification and regulatory requirements may vary depending upon the country and mode of transport. Therefore it is recommended that users verify with the carrier / airline as to which measures to take before the voyage.
<
WARNING:
Ensure that the ventilator’s internal battery is fully charged before connecting the ventilator to an external DC power source. Powering the ventilator using an external 12–30 VDC power source (via the
DC power cable) does not enable charging of its internal battery.
<
WARNING:
The maximum recommended shelf life of the internal battery is 2 years. Do not use a battery that has been stored for 2 years prior to its first use.
<
WARNING:
Periodic recharging is important to help maximize useful life of the battery. Do not store the internal battery for extended periods, without recharging, as this may reduce the maximum life.

Internal Battery
8.1
Battery Capacity
The reserve capacity offered by the internal battery depends on the level of ventilation parameters, the environmental conditions (primarily in terms of temperature) and the physiological characteristics of the patient.
With a fully charged battery at a normal room temperature of 25°C (±5°C), the ventilator can be expected to operate on internal battery power for the average durations shown in
Checking the battery charge level requires that the ventilator be running on battery power at the time of the battery check. To check the battery charge level, temporarily disconnect the ventilator from AC power (while in standby mode or while providing ventilation) and read the percent charge level shown adjacent to the battery icon at the top of the ventilator's display screen.

WARNING:
Before using the ventilator’s internal battery, ensure that the battery is fully charged and that the charge holds. Back up ventilators or those in storage should be connected to an AC power source to protect the integrity of the battery.
:
Note:
Buzzer and battery alarms may occur when the unit is first powered on after the internal battery has been completely drained. Connect to an AC power source and recycle power.
:
Note:
In the event of AC power interruption or disconnection of the external AC or DC power supply, the ventilator automatically switches to its internal battery and the following events occur:
The internal battery indicator at the top left of the ventilator’s front panel is continuously lit. See Figure
.
•
Figure 8-1. Internal Battery Indicator
•
•
A loss of external supply alarm is activated.
The Battery symbol is shown at the top of the screen, on the general information line.
Internal battery reserve capacity is shown to the right of the Battery symbol.
•
If ventilation is stopped, the internal battery reserve capacity is shown as a percentage of battery charge. See
Clinician's Manual 8-3
Internal Battery
Figure 8-2. Battery Reserve Capacity as a Percentage
If the ventilator is running, the internal battery reserve is momentarily shown as a percentage. Then, after the ventilator calculates the battery time remaining (which takes about 2 minutes, depending on the power consumption of the ventilator), the internal battery reserve is then shown in hours
and minutes (rounded to the nearest 10 minutes). See Figure 8-3.
Figure 8-3. Battery Reserve Capacity in Hours and Minutes
8-4
The Low Battery and Empty Battery alarms (see Chapter 5 , Alarms and Troubleshooting ) are triggered
when the internal battery reserve is reduced.
<
WARNING:
Due to the internal battery’s limited reserve capacity, the ventilator should only be operated on the internal battery when no other power source is available. Ensure that the internal battery never becomes fully discharged.
<
WARNING:
When the Low Battery alarm is triggered, immediately connect the ventilator to an AC power supply to maintain ventilation and recharge the internal battery.
From the time that an Empty Battery alarm is activated, if no external supply is connected to the ventilator, other alarms may be triggered due to insufficient supply voltage.
In the final discharge phase, the Empty Battery alarm will become continuous, and ventilation may be interrupted at any time during this phase.
Clinician's Manual
Testing the Battery
:
Note:
The Empty Battery alarm symbol may disappear shortly before the ventilator completely stops, but it always triggers a final, continuous alarm.
8.3
Testing the Battery
The ventilator continuously and automatically checks the state of the internal battery, even when the battery is not used as the main source of energy. The Battery Fault 1 alarm is activated whenever a problem is detected in the battery or the charger.
However, on a monthly basis you should disconnect the ventilator from the external power supply to check the integrity of the connections linking the internal battery to other ventilator components.
8.4
Recharging the Battery
In the event that the battery charge level is considered insufficient, as per the reserve capacity display, recharge of the internal battery is necessary. In general, it is recommended that the ventilator be allowed to charge when the battery drops below 80%, and that the ventilator be recharged systematically after storage and before using it again.
:
Note:
To avoid cycling and extend battery life while connected to an AC power source, the battery will not begin charging until it has dropped below an 85%-90% charge.
•
To charge the internal battery, connect the ventilator to the AC power source.
The AC power indicator illuminates (Figure

Internal Battery
<
WARNING:
Even if the internal battery indicator is off, charge of the battery may sometimes be incomplete regardless of charge time when the ambient temperature is above 40°C (104°F). This is due to the characteristics of the battery’s internal heat safety device.
Although it is not necessary to start the ventilator to charge the battery, charging the battery during operation will increase the time required to fully charge the internal battery.
When recharging a depleted internal battery, it may be necessary to leave the ventilator on charge for up to 6 hours if the ventilator is on standby and about 13 hours if ventilation is operating.
<
WARNING:
Ensure that the ventilator’s internal battery is fully charged before connecting the ventilator to an external DC power source. Powering the ventilator using an external 12–30 VDC power source (via the
DC power cable) does not enable charging of its internal battery.
8.5
Storage
•
If the ventilator is to be stored for an extended period of time, it is not necessary to remove the battery. However, the ventilator should be stored in cool, dry, well-ventilated environment, as follows:
Temperature: approximately 21°C (70°F)
• Humidity: less than 80% RH
:
Note:
When the device is in storage it should be recharged monthly to maximize battery life.
:
Note:
If the battery is stored for more than 1 month at a temperature greater than 21°C (70°F), or for more than 1 or 2 weeks at a temperature greater than 45°C (113°F), the reserve capacity of the battery may be affected. It will then be necessary to recharge the battery before using it again.
:
Note:
If the ventilator has been in storage for longer than 30 days connect it to an AC power source, turn on the unit by the I/O (power) switch at the rear of the ventilator, and let it charge for 15 minutes prior to starting ventilation.
:
Note:
Fully charge the internal battery prior to disconnecting from AC power source (“mains”).
:
Note:
The battery should not be stored for more than 2 years, whatever the conditions.

During breath delivery performance verification for flow and pressure based measurements, the equipment inaccuracy is subtracted from the acceptance specification as follows:
Net acceptance gain = Requirement specification gain – Measurement uncertainty gain
Net acceptance offset = Requirement specification offset – Measurement uncertainty offset
Acceptance limit = ±[(Net acceptance offset) + (Net acceptance gain) × (Setting)]
(Setting – Acceptance limit) ≤ Measurement ≤ (Setting + Acceptance limit)
For derived parameters, such as volume, the individual sensor uncertainties are combined and applied as applicable to determine the acceptance limits.

C Theory of Operation
C.1
Architecture
The Puritan Bennett™ 560 ventilator’s gas delivery system is primarily composed of an airflow generator and a three-way valve to control the patient circuit exhalation valve. The flow generator is a low-inertia, micro-turbine driven by a brushless DC electric motor, while the three-way valve is a proportional solenoid valve.
These two actuators are microprocessor-controlled and perform according to specific control algorithms. The microprocessor control circuit receives its data from the various servo-controlled pressure and feedback flow sensors that are built into the ventilator.
An electrical supply management system performs the energy conversion so the device can switch between the three available power sources to provide power to the internal electronics.
A cooling fan helps maintain the proper operating temperature range for the internal environment of the ventilator. This fan is servo-controlled to maintain the proper temperature for the most heat-sensitive of the ventilator’s components.
C.2
Operation
The operation of the device is based on a self-adapting, closed loop drive system. The speed of the flow generator (turbine) is servo-controlled according to the patient pressure signal or the inspired flow signal.
The turbine speed control algorithms themselves are based on equations that vary according to the ventilation modes, settings, and the respiratory cycle phases. Thus, fixing the pressure rise time or flow pattern has an influence on the level of turbine acceleration at the start of the inspiration phase. The transition between the inspiration phase and expiration phase is controlled by a deceleration or braking algorithm proportional to the pressure difference between the two phases.
The exhalation solenoid valve (three-way valve) is fully closed during the inspiratory phase and is proportionally controlled during the exhalation phase to obtain the bias flow. The speed of the turbine adapts to the exhalation pressure threshold during the entire exhalation phase to maintain the operator-set PEEP.
The flow measurement completes the system by enabling detection of patient inspiratory effort and the triggering of inspiration phases. The flow measurement can also be used to determine the end of the inspiration phase in certain ventilation modes.
C-1
Theory of Operation
The flow measurement is automatically corrected as a function of the atmospheric pressure measured inside the ventilator with the altitude compensation feature. The flow and volume are in Body
Temperature Pressure Saturated (BTPS) conditions. This necessitates that periodic inspections for calibrating the sensors be performed by maintenance technicians authorized by Covidien (see the service manual).
If the altitude compensation feature is active, a corrective algorithm is applied to the inspiration and exhalation flow for volume calculation and the flow set point in volume breath.
The sensor measurement range is software limited from 600 to 1100 hPa.
A cooling fan is provided to maintain the internal temperature of the ventilator within specified limits and to help ensure proper performance and longevity of the device.
Finally, the various measurement signals used in control and detection are protected and specifically filtered in order to limit any risk of disturbance to the device and possible problem.
For an illustration of the ventilator’s gas delivery system, see Figure
:
Note:
The altitude compensation feature is enabled (set to “YES” on the Setup screen) by default and should remain at this setting.
C-2 Clinician's Manual
D Modes and Breath Types
D.1
Modes of Ventilation
This chapter is a general description of the various modes of ventilation and breath types available with the Puritan Bennett™ 560 ventilator.
:
Note:
The default ventilation mode setting is P A/C; for more information, see below.
D.1.1
Assist/Control (A/C) Modes
•
When set to an Assist/Control mode, machine-initiated breaths are delivered at a clinician-set volume or pressure, inspiratory time, and rate. If the patient triggers a spontaneous breath between machine breaths, the ventilator will deliver a breath based on the volume or pressure settings and inspiratory time.
Whether initiated by the patient or the ventilator, all breaths are delivered at the same preset volume or pressure and inspiratory time.
•
The names of the Assist/Control modes are:
V A/C, if the breaths are based on a volume setting
P A/C, if the breaths are based on a pressure setting
D.1.2
SIMV Modes
•
When set to a SIMV (Synchronized Intermittent Mandatory Ventilation) Mode, machine-initiated breaths are delivered at a clinician-set volume or pressure, inspiratory time, and rate. These mandatory breaths are synchronized with patient effort. If the patient triggers a spontaneous breath between machine breaths, the ventilator will deliver a spontaneous breath, which is pressuresupported.
CPAP spontaneous breaths are not available in SIMV modes.
•
The names of the SIMV modes are:
V SIMV, if mandatory breaths are based on a volume setting
P SIMV, if mandatory breaths are based on a pressure setting
D-1
Modes and Breath Types
D.1.3
CPAP Mode
In CPAP mode, the ventilator maintains a constant level of pressure in the patient’s airway.
D.1.4
PSV Mode
PSV mode maintains a constant level of pressure in the patient’s airway during exhalation. In addition, the ventilator applies a clinician-set pressure (Pressure Support) to each of the patient’s breaths. This has the same benefits as CPAP, with the additional benefit of assisting the patient in moving gas into his or her lungs.
D.2
Breath Types
•
•
•
•
The following breath types are available from the ventilator:
Volume controlled breaths in Assist/Control mode (in V A/C or V SIMV)
Pressure controlled breaths in Assist/Control mode (in P A/C or P SIMV)
Pressure-supported breaths in SIMV mode (V SIMV and P SIMV) or PSV
CPAP
D.2.1
Volume Breaths in Assist/Control Mode
In V A/C mode, each delivered breath will be of the selected volume (Vt), delivered over the selected inspiratory time. Inspiration is triggered by patient-generated flow (for assisted breaths) or by the ventilator. For controlled breaths, breath rate (R-Rate) is the controlling parameter. For both controlled and assisted breaths, the inspiration is limited by the volume and is cycled by inspiratory time
(Insp Time).
The shape of the flow waveform can be either a decelerated (D), a (SQ) square, or sinusoidal (S) flow
patterns according to the Flow Pattern setting. See Figure D-1.

In the waveform below, the ventilator delivers a controlled (machine) breath, and calculates the time before another controlled breath must be delivered. The ventilator delivers a second controlled breath at the conclusion of the machine calculated breath time (for simplicity, we will use the term period for “machine-calculated breath time“). Following the second controlled breath, but before another period can elapse, the patient's effort triggers an assisted (or patient-initiated) breath. This restarts the period. At the conclusion of the period, the ventilator delivers another controlled breath. See

Pressure Control Breaths in Assist/Control Mode
In Assist/Control mode (P A/C), each delivered breath will maintain the selected pressure (Pi) maintained over the selected inspiratory time. Inspiration is triggered by patient-generated flow (for assisted breaths) or by the ventilator (for controlled breaths; breath rate [R-Rate] is the controlling parameter). For both controlled and assisted breaths, the inspiratory pressure is limited to the pressure (Pi) setting, and is cycled by time.
The shape of the pressure waveform depends on the setting of the pressure rise time (Rise Time).

The ventilator delivers a second controlled breath at the conclusion of the machine calculated breath time (for simplicity, we will use the term period for “machine-calculated breath time“). Following the second controlled breath, but before another period can elapse, the patient's effort triggers an assisted (or patient-initiated) breath. This restarts the period.

Volume Breaths in V SIMV Mode
In V SIMV the mandatory volume breaths deliver the selected volume (Vt) over the selected inspiratory time (Insp Time). Inspiration is triggered by patient-generated flow (for assisted breaths) or by the ventilator (for controlled breaths; breath rate [R-Rate] is the controlling parameter). For both controlled and assisted breaths, the inspiration is limited by the volume and is cycled by volume and time.
The shape of the flow of volume cycles is of the Square type. See

SIMV mode will also deliver pressure supported breaths (see the description for Pressure supported breaths). The SIMV mode is a combination of mandatory volume breaths and pressure supported breaths. The alternation between them is determined by the setting of breath rate (R-Rate) or period.
In addition, the back up rate will enable the ventilator to ventilate in the case of patient apnea. The back up rate is equal to the maximum between 8 and the breath rate (R-Rate). The “controlled“ cycles following an apnea event will be volume cycles. These cycles end as soon as a new inspiration trigger is detected.
Clinician's Manual
Breath Types
When the patient triggers a breathing effort, the volume and pressure cycles alternate between each other according to the breath rate setting (R-Rate). All the cycles are synchronized on inspiration triggers. A period always includes a volume cycle, plus as many pressure cycles as have been triggered by the patient; beyond the period the following inspiration trigger will initiate a new
volume cycle, and so forth. See Figure D-6.

Pressure Supported Breaths in SIMV and PSV Modes
In P SIMV (or Synchronized) and PSV modes, the supported breaths maintain the selected pressure
(P Support). Inspiration is triggered by patient-generated flow. The inspiration is terminated when inspiratory flow drops to the Exhalation Sensitivity (E Sens) setting.
In P SIMV, additional mandatory pressure breaths will be delivered, dependent on the selected
Breath Rate (Rate).

Ventilation Modes and Apnea
In SIMV mode with apnea time (Apnea Time) settings, the ventilator will sound an Apnea alarm if no patient effort occurs during the apnea time. During an Apnea alarm, the ventilator delivers breaths at a breath rate (backup rate) equal to the maximum of eight and the breath rate setting (R-Rate). If the patient initiates a spontaneous breath, the ventilator will stop the controlled breaths and return to the previous operating parameters.
In PSV mode, the back-up rate is activated so that the ventilator will automatically begin to deliver breaths at the breath rate (Backup R) setting if no patient effort occurs for the Apnea Time setting.
The pressure during a back-up breath is equal to the Pressure Support (P Support) setting before the apnea condition began. If the patient initiates a spontaneous breath while the back-up rate is in effect, the ventilator will return to the previous operating parameters.
In CPAP, a backup rate is not set, but the operator must still set an apnea time (Apnea Time). In that case, the ventilator will sound an Apnea alarm if no breath is triggered by the patient in the apnea time; however, no back up breaths will be generated.

WARNING:
To ensure proper performance of the ventilator, use a patient circuit recommended by Covidien in this manual; see Chapter
6 , Installation and Assembly and Appendix
H , Parts and Accessories . The total
specified length of the patient circuit tubing as measured from the ventilator outlet to the ventilator inlet is 1.1 meters (3.6 ft) to 2.0 meters (6.6 feet). The tubing must conform to all applicable standards and must be fitted with Ø 22 mm terminals that also conform to all applicable standards. Ensure that both the length and the internal volume of the patient circuit are appropriate for the tidal volume: a corrugated tube of Ø 22 mm for adult patients, and a corrugated tube of Ø 15 mm for pediatric patients with a tidal volume lower than 200 ml.

Alarm Pause
The audible and visual alarms cease and the alarm paused symbol appears. The symbol will remain until the cause of the alarm is addressed. For example, when the ventilator is running on internal battery, the AC Disconnection alarm may be paused, and the alarm paused symbol will appear until the device is plugged into AC. The paused alarm will be captured in the alarm log screen and can be reactivated.
Alarm Reset
Used only for the High Pressure alarm, this function resets the visual alarm message.
Apnea
The absence of breathing or a breathing pattern capable of supporting an individual's respiratory needs.
Apnea Index (AI)
The apnea index is the average number of apnea events per hour of ventilation. It is based on the
Apnea alarm.
Apnea Time
Time allowed between breath starts before Apnea alarm occurs when no patient effort is detected.
Assist/Control
In Assist/Control mode, the ventilator delivers an assisted breath of a set volume or set pressure when the patient's breathing effort creates a flow or pressure drop that is greater than the sensitivity setting. In absence of patient breathing effort, the ventilator will deliver a controlled breath of the set volume or pressure. (Does not apply in PSV/CPAP mode).
