2-8 Site Preparations
•
Make sure that you have read all applicable instructions before attempting to install the
wall mount.
•
Wall mounts that are intended to support monitors must be capable of supporting four
times the weight of the monitor when properly installed.
•
If wall mounts are to be installed on plaster board walls, we recommend that the mounts
be installed using steel or plywood plates sufficient to distribute the load over a large
section of the wall. Lead expansion bolts are neither adequate nor safe for this
purpose.
•
It is the responsibility of the hospital, institution, or its designated representatives to
determine that the wall is adequate to safely mount monitoring instrumentation. This
includes the selection of and proper installation of the appropriate fasteners and mounts.
In a new construction, or in a remodelled construction where the wall can be completely
or partially removed, a 16-gauge steel stud should be mounted for the purpose of
attaching the wall channel. This design safety factor is based on four times (4x) the
maximum rated load.
•
GCX Wall Channel: Always reposition the adjustable channel safety stop under the
adapter plate when the height of the monitor is changed.
•
The channel safety stop prevents the mounting device from inadvertently falling or
being pulled out of the wall channel. Do not remove this stop while the mount is
supporting a monitor.
•
Do not mount any portion of the monitor over a patient’s bed.
•
Do not exceed the maximum rated load specified for each wall mount.
•
Ensure that no electrical wiring, utilities, or piping interface with the selected wall
mounting location.
•
Do not install wall channel onto solid brick or brick veneer walls. Do not attempt to
install wall mounts onto crumbly wall material.
•
Check the mounting hardware holding the wall channel or bracket to the wall every 12
months. Tighten if necessary.

About the
Battery
Storing the monitor for a long period of time without charging the battery can degrade the
battery capacity. A complete battery recharge (>90%) requires 8 hours in standby mode or 14
hours in operational mode. If the battery needs charging, connect the monitor to the AC outlet
as described “Charging the Battery”on page 3-9
If the monitor operates for less than one hour on battery power before the low battery alarm
occurs, the battery should be conditioned. See “Electrical”on page 12-3 for typical battery
operating times and conditions.
If the same symptom persists after the battery is conditioned and indicating a full charge, the
battery should be replaced (see “Removing the Battery”on page 7-4 for more information).

Battery
Guidelines
To get the most out of the battery, observe the following guidelines:
•
The shelf-life of a fully charged battery is about 6 months.
•
After a battery has been activated, keep it charged. If it is not in use, recharge it every 3
to 4 months.
•
Condition the battery approximately every 200 deep discharges.
•
Remove the battery from the monitor if it is not being used regularly. (Leaving the
battery in a monitor that is not in regular use using the battery will shorten the life of
the battery).
•
Battery Disposal - We recommend replacing the monitor’s sealed, lead-acid battery at 2
year intervals. Follow local governing ordinances and recycling plans regarding
disposal or recycling of batteries and other device components.
•
Do not dispose of the battery in normal waste containers.

If the battery operating time is less than 30 minutes, the battery icon flashes. A low
priority audio alarm sounds (1 beep every 4 seconds).
•
When the battery is empty, a "Low Battery" INOP message displays in the Message
frame and the audible alarm sounds. Pressing any front panel button clears the INOP
and silences the audible alarm. The battery icon continues to flash until the monitor is
powered down or automatically switches off.
If the new battery is partly or fully charged, the monitor starts operating.
Charging
the Battery
A complete battery recharge (>90%) requires 8 hours in standby mode or 14 hours in
operational mode.
To charge the battery:
Step
Action
1
Connect the monitor to the AC power source using the proper power cord.
2
Verify that the AC Input Indicator LED is lit.
3
Charge the battery for at least 8 hours. The battery may require a full discharge/
charge cycle to restore it to its normal capacity.
4
To check for a full charge, perform the procedure described in “Battery
Performance Test”on page 4-22.

Battery Maintenance
Conditioning
a Battery
Battery conditioning re-calibrates the battery to ensure that it has accurate information on the
actual battery capacity.
Warning
Never use a monitor that is monitoring a patient to perform battery conditioning.
Why is Battery
Conditioning
Necessary?
The capacity of a battery decreases gradually over the lifetime of the battery. Each time a
battery is charged its capacity decreases slightly. Therefore, the operating time of a monitor
running off the battery also decreases with each charge cycle.
Battery conditioning ensures that the value storied in the battery for its fully capacity takes
account of this decrease, so that the remaining battery charge can be calculated accurately,
and the low battery warning given at the right time.
When Should
Battery
Conditioning
be Performed?
How to
Condition a
Battery
Battery conditioning should be performed:
•
Every 200 deep discharge cycles.
We recommend two full charge and discharge cycles to ensure proper conditioning,
independent of the initial condition of the battery.
If you need to continue battery powered monitoring, replace the battery in the monitor with a
different charged and conditioned battery. You cannot condition a battery in a monitor that is
being used.
Step
3-10 Maintaining the Monitor
Action
1
Insert the battery that is to be conditioned into a monitor that is not currently
being used.
2
Disconnect the monitor from the AC power supply.
3
Turn on the monitor, and leave it on until it switches off automatically.
4
Turn the monitor Off using the On/Standby button located on the front panel.
5
Reconnect the monitor the AC power supply.
6
Charge the battery until it is full. (When you turn the monitor On, the 5 bars in
the battery gauge on the main monitoring screen will be illuminated).
7
Repeat steps 2 to 6.

Battery
INOP
Messages
The following battery-related INOP messages are issued by the monitor. All Battery INOPs
continue until the monitor is plugged into the AC power or the INOP condition is fixed.

Performance Procedures
Barometric
Pressure
Check and
Calibration
Check the barometric pressure value in the CO2 module as follows:
Step
Action
1
Enter the Power-Up Defaults Menu (see ““Power-Up Defaults Menu” on
page 5-3“for instructions on accessing this menu).
2
Select the Enter Diagnostic Mode? option.
3
From the popup menu, select Yes. The Diagnostic Menu displays.
4
Select the CO2 Test option.
5
Connect a FilterLine to the CO2 patient monitoring input connector. This
activates the pump in the CO2 module.
6
Check the status line at the top of the screen. It will display "CO2 pressure in
mmHg (ambient/cell) xxx/yyy" where xxx is the ambient pressure and yyy is the
measured cell pressure. The values are displayed with a resolution of 2 mmHg
(0.3 kPa) up to 475 mmHg (63.2 kPa) and a resolution of 1 mmHg (0.1 kPa)
from 475 mmHg (63.2 kPa) to 825 mmHg (109.7 kPa). Check whether the
ambient pressure (X1) matches (within the acceptable tolerance of ±12 mmHg)
the reference value you have received. If so, proceed to the “Leakage Check”. If
the value is not correct, calibrate as follows.
7
Select Set Barometric Pressure (mmHg). An adjustable value in mmHg is
activated.
8
Select the value that matches the reference value received from a reliable local
source, such as an airport, regional weather station or hospital weather station.
9
If the selected value is not with ±12mmHg (1.6 kPa) of the current measured
ambient pressure, verify the reference value by getting another reading from a
different source. If the ambient pressure displayed also differs from the new
reference by more than ±12mmHg (1.6 kPa), the CO2 module should be
replaced.
10
Confirm the barometric pressure setting by clicking on the adjusted value so that
it is no longer highlighted.
11
Check that the ambient pressure displayed in the CO2 Pressure line at the top of
the screen is the same as the value that you selected from the list in Step 8.
Testing the Monitor 4-31
Performance Procedures
Leakage
Check
The Leakage Check consists of two parts:
•
Part 1 - Checking the tubing between the pump outlet and the CO2 module outlet.
•
Part 2 - Checking the tubing between the pump inlet and the FilterLine inlet.
Note
Check the flowmeter’s user guide for details on how to make a correct flow reading.
Part 1
Step
Action
1
Check the ambient and cell pressure shown in the status line on the screen. The
cell pressure should be approximately 20 mmHg (2.7 kPa) lower than the
ambient pressure.
2
Connect the flowmeter outlet to the FilterLine inlet using a flexible connecting
tube.
3
Block the CO2 module outlet using your fingertip and observe the flowmeter
display. The value on the flowmeter (X2) should decrease to between 0 and 4 ml/
minute. If the value is not within the tolerance limits, there is a leakage between
the pump outlet and the CO2 module gas outlet.
4
If a leakage is found in Step 3, open the CO2 module and check the tubing
connections at the pump outlet and the module CO2 gas outlet. If the connections
are good, then there is leakage in the module and the CO2 module must be
exchanged.
Part 2
Step
4-32 Testing the Monitor
Action
1
Disconnect the flowmeter from the Part 1 setup and connect the flowmeter inlet
to the CO2 module gas outlet.
2
Leave the FilterLine connected to the CO2 module inlet.
3
Block the inlet of the FilterLine using your fingertip and observe the flowmeter
display. The value on the flowmeter (X3) should decrease to between 0 and 4 ml/
minute. If the value is within the tolerance limits, there are no leakages and the
leakage check is completed. You can proceed to the “Pump Check”.
4
If the value is not within the tolerance limits, there is a leakage between the
FilterLine inlet and the pump inlet.
5
Check the FilterLine connections and open the monitor to check the tubing
connections at the pump inlet and the CO2 module gas inlet. If the connections
are good, try replacing the FilterLine and repeating the leakage check. If the
situation remains, there is a leakage in the tubing and the CO2 module must be
exchanged.
Performance Procedures
Pump Check
Step
Action
1
Connect the flowmeter inlet to the CO2 module gas outlet.
2
Connect the FilterLine to the CO2 module inlet.
3
Block the inlet of the FilterLine using your fingertip and observe the cell
pressure to the right of the slash symbol on the top row of the CO2 Test display
screen.
The cell pressure (X4) should be more than 120 mmHg below the ambient
pressure shown. If the pressure difference is less than 120 mmHg, the pump is
not strong enough and should be replaced (regardless of the Pump Op Time).
Flow Rate
Check and
Calibration
Step
Action
1
Connect the flowmeter to the CO2 FilterLine.
2
On the flowmeter, check the flow that the CO2 Pump draws (X5). The nominal
value is 50; the acceptable limits are 42.5 and 65 ml/minute. If the value is
within these limits, proceed to the CO2 Gas calibration check. If not within the
limits, calibrate as follows.
3
Select Flow Rate Check and Calibration. Adjust the flow in the monitor by
selecting Increase Flow or Decrease Flow until it is as close as possible to 50
ml per minute as indicated on the flowmeter gauge. The pump voltage displayed
on the second row of the CO2 Test screen will vary as the flow is changed.
4
When you are satisfied that the flow is set as close as possible to 50 ml per
minute, select Store Flow to confirm the setting
Note
If the adjusted flow is not stored within 60 seconds of the adjustment, the old flow setting is
restored. If the flow cannot be adjusted to within tolerance, the pump should be replaced. If
the flow adjustment still cannot be made, this indicates a fault in the CO2 module, which must
be replaced.

Performance Procedures
CO2 Gas
Measurement
Calibration
Check
After switching the monitor on, or after turning on the etCO2 On/Off setting in the etCO2
frame, wait at least 20 minutes before checking the calibration.
Step
Action
1
Check that the 5% calibration gas and flow regulator are connected.
2
Calculate the expected measurement value in mmHg as follows:
0.05 x (ambient pressure) / 1.03 = value mmHg
i.e. 0.05 x 736 mmHg / 1.03 = 35.7 mmHg (with an ambient pressure of 736
mmHg)
Note: Dividing by 1.03 compensates for the dry calibration gas at room
temperature, relative to breath gases containing water vapor and at body
temperature.
3
Select CO2 Calibration. Wait for the status message "CO2 module reset in
progress" to disappear. Open the valve on the flow regulator to allow 5% CO2
gas to flow into the monitor. Allow the displayed CO2 value (third row of CO2
Test menu) to stabilize.
4
Check that the CO2 value on the monitor matches the calculated mmHg value
±2.6 mmHg. If the value is outside the tolerance, calibrate as described in Step 9
to 13.
5
Disconnect the 5% calibration gas and connect the 10% calibration gas.
6
Calculate the expected measurement value and tolerance in mmHg as follows:
0.1 x (ambient pressure) / 1.03 = value mmHg
±0.07 x (value mmHg) = tolerance
i.e. 0.1 x 737 mmHg / 1.03 = 71.6 mmHg (with an ambient pressure of 737
mmHg)
±0.07 x 71.6 mmHg = ±5.01 mmHg tolerance
4-34 Testing the Monitor
7
Open the valve on the flow regulator to allow 10% CO2 gas to flow into the
monitor. Allow the value to stabilize.
8
Check that the value on the monitor (X6) matches the calculated mmHg value
within the calculated tolerance. If so, the CO2 module is correctly calibrated. If
the value is outside the tolerance, calibrate as follows.
9
If not already connected, connect the 5% calibration gas.
10
Select CO2 Calibration to enter the Calibration sub-menu. Wait for the status
message "CO2 module reset in progress" to disappear.
11
Select the value for the calibration gas (The default value is 5%).
12
Select Start Calibration and open the valve on the calibration gas to allow CO2
gas to flow into the monitor. Allow the value to stabilize before the start of the
calibration. Leave the valve open until the monitor gives a prompt that the gas
can be removed.

A NBP Test screen is provided to facilitate troubleshooting problems and performing
verification testing for the NBP subsystem. Typically, when these tests are performed, the
pneumatic system is connected to an external pressure-reading device and a closed reference
volume. The NBP Test screen provides a real-time numeric display of the pressure in the
pneumatic system, means for controlling the pump and valves are open or closed.

Activate Pump
As long as the NBP button is pressed,
the pump runs. If system pressure
reaches the hardware over-pressure
protection point (280 to 330 mmHg or

and the pump disables, until the pressure
falls below the safety threshold.
Open Both Valves
As long as the Volume button is pressed,
the safety valve and proportional valve
opens and remains at maximum.
Deflate
As long as the Alarm Silence button is
pressed, the proportional valve opens
and bleeds off pressure at the rate of 3
±1.5 mmHg/s. It is useful to control the
bleed rate to 3mmHg/s to facilitate
certain AAMI SP10 tests. Any time the
bleed rate falls below 3 mmHg/s, the
valve opens and remains at maximum as
long as the button is pressed.
Offset Adjustment
Momentarily press the Contrast Adjust
button invokes the Zero Calibration
routine that is performed immediately
prior to each blood pressure
measurement. This routine looks at the
pressure in the system, and if the
pressure is non-zero, an offset is applied
which causes the system pressure to
display as Zero.

Support Strategies
Support Strategies
This section provides a summary of how the monitor was designed to be supported and how
Philips provides that support.
There are two main methods of repairing the monitor:
•
Unit exchange
•
Bench repair
Unit
Exchange
The primary repair method used by Philips service personnel is unit exchange. The current
design of the monitor requires testing if the case is opened.
Bench
Repair
The secondary repair method is bench repair. Special tools are required and are listed in
“Equipment” on page 4-8. If the case is opened, specific tests must be performed. These tests
are listed in detail along with the Test Map in Chapter 4.
At the Philips Parts Center, we will stock the board level assemblies and mechanical parts
based on existing failure data and customer demand. These parts are listed in Chapter 8. The
availability of additional spare parts will be notified by service notes.
The troubleshooting guide in Chapter 6. is sufficient for assembly level bench repairs. Before
a repair is performed, consider whether a repair or a replacement is most suitable.

Theory of Operation and System Architecture
Theory of Operation and System Architecture
This section contains a high level overview of the theory of operation of the major functional
modules of the monitor. Philips service providers perform Bench Repair at the assembly level.
For this purpose, they should review this high level information.
Please be aware that Philips only stocks assembly level parts.
System
Overview
The monitor is a full function monitor for use on adult and pediatric patients.
The functions performed by the system include monitoring patient ECG, heart rate,
respiration rate, blood pressure, blood oxygen saturation, carbon dioxide1, and temperature.
In addition to monitoring and displaying the status of these physiological parameters, the
instrument performs various microprocessor-programmed analytical functions, such as:
•
Creating both visual and audible alarm signals when set limits are violated.
•
Creating and displaying warning messages when conditions are detected that would
degrade or prevent valid measurements.
•
Creating and displaying trend waveforms or tabular data.
•
Providing a synchronizing pulse for defibrillator operation.
•
Providing input to an optional recorder for printout of current or trend waveforms or
tabular data.
The monitor is essentially a battery-powered instrument. An internal charging unit is designed
to accept an external AC line voltage. The charger uses the external power source to maintain
a "float" voltage source available from the batteries.

Theory of Operation and System Architecture
Isolated
Front End
The Isolated Front End section includes all of the circuitry to convert ECG, SpO2, and
Temperature measurements to digital format; and to connect this information to the processor.
The Respiration detection is obtained from two of the three electrodes of the ECG
connections.
NBP Front
End
The NBP section contains the pumps, valves, pressure measurement circuitry, and control
circuitry for the non-invasive blood pressure measurement. Pressure data is converted to
digital format and conveyed to the processor section.
Power
System
The power system section contains a power supply capable of operating the monitor and
charging the battery from an AC source of 100 to 240 VAC at 50 to 60 Hz. This section also
contains the circuitry. The battery provides the operating power for this power.
Microprocessor,
Memory and
Control
The Microprocessor, Memory and Control section contains the system CPU and all digital
support circuitry. The latter includes the RAM, non-volatile memory, and real-time clock.
This section also contains the display logic, keypad (switch) interface logic, RS-232 I/O
control, defibrillator synchronization control, and printer logic.
Display
The display is a TFT (color), backlit fluorescent LCD unit. The active screen size is 8.3 x 6.2
in (210.8 x 157.5 mm): 10.4 in (264.2 mm) diagonally, and the resolution is 640 x 480 pixels.
Keypad
The keypad circuit contains five push-button membrane switches and two green LEDs. The
LEDs are driven by the power supply system and indicate the power source.
Signals from LEDs are returned to the microcomputer for processing and control as required.
The On/Standby button, connected directly to the power supply, toggles the power between
On and Standby modes. When in Standby, the display is blank, and no monitoring is
performed. However, the batteries are charging if an AC source is connected to the rear panel.
The Audio Alarm Control button is connected directly to the processor and to the system
power supply. Pressing this button turns off the battery fuse alarm in the system power
supply. Response of the processor depends upon the action in pressing this button. If
momentarily pressed (less than 2 seconds), alarms are paused temporarily for a preset interval
determined by the menu selection. If pressed twice within 10 seconds, the alarm sounding for
a specific parameter is silenced temporarily for a preset interval determined by the menu
selection. Other alarms, not related to this parameter, can still sound during this period. If
pressed and held for 2 seconds or more, the Audio Off condition is initiated.
The NBP button is connected to the processor. Response of the processor depends upon the
state of NBP operation at the time and the action in pressing this button. If momentarily
pressed, (less than 2 seconds), a single NBP measurement is obtained. If pressed for 2 seconds
or more, the processor initiates a STAT monitoring sequence. Pressing the NBP switch at any
time a pressure measurement is in effect causes the processor to terminate the measurement
and to deflate the cuff.
Training 11-7
Theory of Operation and System Architecture
The Contrast button operates in conjunction with the navigation wheel to determine the
apparent contrast setting in the display. Changing the contrast is a change in the viewing
angle. Outputs of the button and wheel are connected to the processor.
Momentarily pressing the button sets the contrast to mid-range, factory-default value.
Momentarily pressing of the button, followed within 3 seconds by a rotation of the wheel are
processed to vary the contrast of the display. When there has been no wheel rotation for 3
seconds, the contrast control function is terminated by the processor. The contrast control
function is also terminated if the wheel is pressed any time within this 3 second interval.
Operation of the Volume button accomplishes similar functions for the volume of the heart
rate audible tone as the display contrast control button does for the display. Pressing this
button, enables the wheel to vary the tone volume.
Navigation
Wheel
This is a rotating, push-switch wheel. The associated wheel circuitry generates a pulse when
pressed and generates a digitally encoded pair of quadrature signals whose relative
magnitudes and polarities represent the angular position of the wheel. These outputs are
connected to the processor where they are interpreted as required for the functions involved.
Successive angular positions determine the direction of wheel rotation.
In addition to the functions performed when in conjunction with the keypad as described
above, the wheel operates in conjunction with the display to select menus and lists of
parameter variables.
RS-232 I/O
This is a rear panel 9-pin connector providing interfaces with other computer systems or
equipment. The driver for this "port" is a Universal Asynchronous Receive-Transmit (UART)
integrated circuit that interfaces this port with the microprocessor. The baud rate for this serial
transmission function is programmable from 1200 baud to 38.4 kilobaud.
Pin number 9 of the RS-232 connector is reserved for a Nurse Call signal. The nurse call
signal reacts when a low, medium, or high level alarm is activated.
Defib Sync
Pulse
The rear panel connector for the Defib Sync Pulse is keyed so that the connection of a cable
can be detected by the processor. When a connection is detected, the processor software
initiates the generation by hardware of a TTL-compatible pulse capable of driving 1 TTL load
over a three-meter cable with less than 200 pF capacitance.
The defib pulse is triggered by the detection of the R-wave in the QRS sequence of the ECG
wave-form complex. The pulse signal is active for 100 ±10 ms.
Speaker
11-8 Training
The speaker is capable of providing 73 dBA of volume at a distance of one meter during
alarm conditions. The processor drives the speaker in different patterns as specified for the
different alarm priorities and conditions. Refer to the C3 Instructions for Use guide for
descriptions of alarm responses.
Theory of Operation and System Architecture
Recorder
The optional recorder module is installed in the right panel of the monitor. Refer to the C3
Instructions for Use guide for printing procedures. It provides users with the capability to
obtain hard-copy records of selected vital sign information.
Basic control of the recorder is implemented by two push-button controls on the recorder’s
front panel. The Continuous button is used to obtain continuous recordings of the real-time
waveforms displayed in the top two graphic frames. Along with the waveforms, the recorder
prints the values of the vital signs being displayed. The printing continues until the user
presses either recorder button a second time.
The Snapshot button initiates a snapshot printout for 20 seconds of the same information
recorded by the continuous control.
If scrolling is enabled in a display frame containing trend data when the Continuous button is
operated, then the trend record for that vital sign is printed. If the Snapshot button is
operated, then only the trend data on the display is printed.
The recorder may be programmed via the monitor menu display to print a snapshot recording
when an alarm condition occurs.
Printing is accomplished on 50 mm wide thermal paper at recorder speeds programmable up
to 55 mm/s.
ECG
Processing
The technique used in ECG senses the varying potential difference between two points at the
skin surface which respond to the electro-chemical actions of the muscular activity of the
heart.
Three electrodes are attached to the patient’s right arm (RA), left arm (LA) and left leg (LL).
The varying potentials at these locations are cable-connected to the ECG circuit inputs where
they are conditioned, and the difference of potential between two selected leads is digitized
before transmitting through opto-isolators to the processor. The processor-installed algorithms
operate on the signals to develop drivers for the graphic display and to compute the heart rate
in beats per minute (BPM).
In addition to the acquisition of the QRS waveform complex, the ECG input and subsequent
signal processing computing circuitry perform a number of other functions:
Respiration
Processing
•
They detect a "lead-off" condition if one of the electrode connections is disrupted.
•
They detect the presence of pacemaker signals within the QRS waveform complex of
the ECG.
•
They generate a synchronization pulse for external use with defibrillators. The Defib
Sync Pulse output is available at a connector in the rear panel.
The patient’s respiration is detected by using two of the three leads of the ECG electrodes and
cable. A low-level excitation signal is applied to these leads, and the variation of the thoracic
impedance caused by the breathing is sensed and processed for display and measurement.
Training 11-9
Theory of Operation and System Architecture
NBP
Processing
The NBP processing uses an oscillometric technique to provide needed measurements at
selected intervals. This technique uses an inflatable sphygmomanometer cuff similar to those
used by clinicians in routine measurements.
A motorized pump inflates the cuff to approximately 180 mmHg initially, at which point the
pressure effectively stops the flow of blood. Then, under monitor control, the pressure in the
cuff is gradually reduced, while a pressure transducer detects the air pressure and transmits
the parameter signal to the NBP input circuitry.
As the pressure is reduced, blood flows in the previously occluded artery, and changes the
measurements made by the transducer. The point at which oscillation increases sharply is
defined as systolic pressure. As the cuff continues to deflate, oscillation amplitude increases
to a maximum, and then decreases. The peak oscillation amplitude is defined as the mean
arterial pressure. The point at which the system detects a rapid decrease in oscillation is
defined as the diastolic pressure.
SpO2
Processing
Measurement of oxygen saturation in the blood uses a specrophotometry technique. It is based
on the facts that oxyhemoglobin and deoxyhemoglobin differ in their absorbtion of red and
infrared light, and that the volume of arterial blood in tissue changes during the pulse.
Using these facts, a pulse oximeter passes red and infrared light into an arteriolar bed and
measures changes in light absorption during the pulsatile cycle. The light sources are red and
infrared light emitting diodes (LEDs), while the detection is accomplished by a photo diode.
To identify the oxygen saturation of arterial hemoglobin, the monitor uses the pulsatile nature
of arterial flow. During systole, a new pulse of arterial blood enters the vacular bed, and both
blood volume and light absorption increase. During diastole, blood volume and light
absorption reach their lowest point. The measurement is based upon the difference between
maximum and minimum absorption, focusing on the pulsatile arterial blood.
In addition to the oximetry function, the input signals may be used to calculate heart rate.
CO2
Processing
The Microstream CO2 board consists of an 80C552 Controller, the memory system (Flash
ROM, RAM, PLA, etc.), the Flow system (FilterLine recognition system, Inlet, solenoid
valve), Measurement Cell (Exciter, IR Source, Detectors and Temp Sensor) and an analog
section with ADC.
The gas inlet allows the connection of Microstream FilterLines. The FilterLines are detected
by the Optical Code Recognition.
Temperature
Processing
Measurement of patient temperature is accomplished by processing the signal from a probe
containing a resistor whose impedance is temperature dependent. The class of such
components is called thermistor.
The C3 is designed to accept the signals from electrically isolated Series 400 probes
manufactured by Yellow Springs Incorporated. Interchangeable probes in this series may be
used for esophageal, rectal, skin or surface, or airway temperature measurement. Probes are
furnished with a standard 10-feet lead. Extension leads are available.
The signal from the probe is conditioned by the monitor’s input circuitry, processed, and used
to drive the numeric display.
