Section 2-Functional Verification
Introduction
Section 2
Functional Verification
Introduction
The functional verification procedures ensure proper operation of the Encore monitor and its
options. These procedures should be performed following module-level repairs, calibration, or
whenever there is a question about the accuracy or safety of the patient functions.
The calibration procedures in Section 3 should be used to return the monitor to operation within
its performance specifications. If the monitor does not pass the functional verification, or when it
is time to do a routine calibration, see Section 3.
WARNING
Whenever the monitor is opened for calibration or repair, a risk (leakage) current
safety check as well as a dielectric strength integrity (hi-pot) test must be
performed as described in this section.
The Encore’s service menu facilitates the functional verification. It has several features for testing
and verifying the NIBP (cuff) channel, display, invasive pressure channel, and printer. Refer to
Section 1 for information about the Service Menu.
Self Tests
Many functions, such as alarms, waveform and scale sizing, and printer control, are software
operations. During the monitor’s power-up self-test, the integrity of all programming is checked
first. If software testing is successful, hardware tests are initiated. If all testing is successful, the
monitor is ready for use. (See Section 4 for information on error messages.)

Section 2-Functional Verification
Safety Tests
Safety Tests
The following two safety tests, a risk (leakage) current safety check and a dielectric strength
integrity (hi-pot) test, must be performed whenever the Encore has been opened for calibration or
repair.
note...
A hi-pot test is only required if the monitor has been opened.
Risk (Leakage) Current Test
A risk (leakage) current test must be performed to verify that the patient remains electrically
isolated from the power circuits of the Encore.
Check leakage currents using a Dynatech/Nevada 431F-1D safety analyzer or its equivalent. The
source current should not exceed 10µA rms. The sink current, measured between the isolated
patient connections (ECG) and the dc power input connector of the monitor, should not exceed
20µA rms. See the analyzer's operator's manual for the proper safety check procedure.
note...
Because of the all-insulated construction of the monitor, an Enclosure Leakage
Current Test to ground is not necessary.

Section 2-Functional Verification
Dielectric Strength (Hi-Pot) Test
Because of the close spacings of the monitor's internal components and the critical positioning of
the insulation sheet within the monitor, Protocol Systems, Inc. recommends that a dielectric
strength test be performed following any procedure in which the monitor is opened.
WARNING
The Hi-Pot test is extremely hazardous. Only qualified service personnel should
perform this test. Conduct the test only on an insulated table top, away from other
people and equipment.
Use a Rod-L Model M100AVS5 high-voltage potential tester, or equivalent. Refer to the Rod-L
instruction manual for operating information and safety recommendations.
1. Set the high voltage potential of the tester as specified in the table below.

Functional Verification
The functional verification must be done only when the monitor is fully assembled. If the monitor
has been stored for longer than one month without the monitor connected to the ac adapter (for
recharging), the battery voltage must be checked. The battery must be replaced if it cannot hold a
charge. Refer to Section 4 for a battery capacity test.
note...
Some configurations of the Encore monitor do not include impedance
pneumography (RESP) and other neonatal monitoring parameters. In these
versions, RESP does not appear in menus or on the screen displays. You can ignore
RESP and other terms relating to neonatal monitoring when indicated in the
following instructions.
If you plan to use a Dynatech/Nevada model 213A, 215A, or 217A Patient Simulator
to simultaneously simulate ECG and invasive blood pressure, see Appendix B for
important information.
Before starting the verification procedures, charge the battery for at least 8 hours
with the monitor turned off. (Charge for 12 hours if a Printer or SpO2 module is
attached.)
Power System
The following steps check the integrity of the Encore’s power system.
1. Turn the ac power adapter’s power switch off.
2. Plug the ac power adapter into an ac mains receptacle and connect it to the Encore’s right side
panel dc power connector.
3. Check that the green LED charging indicator on the monitor’s right side panel is off.
4. Turn on the power adapter’s power switch.
5. Check that the green LED on the power adapter turns on and that the green LED charging
indicator on the monitor’s right side panel turns on.
6. Disconnect the power adapter from the monitor. Check that the monitor’s green LED charging
indicator on the right side panel turns off.

CO2 Verification Preparation
The mainstream and sidestream CO2 functional verification procedures require calculating the
local barometric pressure and partial pressure of the test gas (in mmHg) to compare to Propaq
Encore displayed values.
Local barometric pressure
The first step is to determine the local barometric pressure:
1. Determine local altitude above sea level.
For worldwide locations, obtain altitude from local geological maps (U.S.G.S. maps in the
United States) or other local references on the maps. Refer to the table titled: Uncorrected
Barometric Pressure as as Function of Altitude; use this table to determine the local uncorrected
pressure (LUP).
2. Determine ATIS reported pressure (inches or millimeters of Hg).
For U.S. locations, consult local telephone directories to obtain the Automated Terminal
Information Service (ATIS) number, typically listed under United States Government Offices,
Department of Transportation, Federal Aviation Administration, and Air Traffic Control
Towers.
32
Propaq Encore Service Manual
Section 2-Functional Verification
Functional Verification
Among various statistics reported is the “altimeter,” which is given in four integers. The four
digits represent the barometric pressure as referred to sea level, in units of inches of mercury,
with an assumed decimal point occurring between the second and third numbers.
For worldwide locations, equivalent altimeter statistics, in millimeters of mercury, may be
obtained from local agencies.
note...
The difference in altitude between the calibration site and the ATIS site should not
be greater than 30 m or 100 ft.
3. Determine local barometric pressure using LUP and ATIS. Apply the ATIS and LUP values to
the following formula to calculate the local barometric pressure (mmHg):
Local Barometric Pressure =
0.033421 x LUP x ATIS (ATIS in inches of Hg)
0.00131579 x LUP x ATIS (ATIS in mm of Hg)
Example 1
Step 1. The altitude is 5000 feet. The local uncorrected pressure (LUP) is determined from the
following table to be 632.35.
Step 2. The reported ATIS is 30.09 inches Hg. (Altimeter: three zero zero niner.)
Step 3. Multiply the LUP (632.35) times the ATIS (30.09) times 0.033421.
This gives the local barometric pressure of 635.92 mmHg.
Example 2
Step 1. The altitude is 1000 meters. The local uncorrected pressure (LUP) is determined from the
following table to be 674.11.
Step 2. The reported ATIS is 764.29 mmHg.
Step 3. Multiply the LUP (674.11) times the ATIS (764.29) times 0.00131579.
This gives the local barometric pressure of 677.92 mmHg.
Partial pressure of test gas source
To determine the partial pressure of test gas source multiply the local barometric pressure (as
determined in step 3 above) by the certified percentage (±0.01% accuracy) of the test gas.
Example
The local barometric pressure (as calculated in Example 1 above) is 635.92 mmHg.
The certified CO2 gas percentage is 5.00%.
Determine the CO2 partial pressure by multiplying (635.92) x (0.0500).
This gives the partial pressure of the CO2 as 31.8 mmHg.

Mainstream CO2 Verification Procedure
This procedure verifies the accuracy of the Encore’s mainstream CO2 (MCO2) measuring system. If
verification test results exceed specification limits, calibration as instructed in Section 3 MAY or
MAY NOT be required—there are multiple possible sources of errors in testing as listed in the
table on page 38.
1. Connect a MCO2 sensor with airway adapter to the Encore MCO2 input connector.
2. Turn on the Encore. Press ALARM SUSPEND/RESUME to disable the alarms.
3. Press SETUP > MORE > MORE (>SERVICE > YES > MORE > MORE > SETTINGS, for software
versions 2.0 and greater) and then set the CO2 measurement units to millimeters of mercury
(mmHg).
4. Allow the monitor and sensor to warm up for at least 15 minutes.
note...
Possible errors may be caused if the area has high background CO2 levels or if CO2
has been forced outside of the airway adapter and into the sensor itself. To reduce
the background CO2 level, the area should be well ventilated and, preferably, the
technician should be the only person present. If CO2 has been forced into the
sensor, allow 24 to 48 hours for the CO2 to dissipate.
5. After 15 minutes, check that the CO2 reading (of ambient room air) on the Encore display is
1 mmHg, ±1 mmHg.
6. Install a rubber stopper in each end of the sensor airway adapter. (Refer to the Required
Equipment list on on page 18.)
7. Connect the CO2 gas source through the hole in the stopper on one end of the airway adapter.
Leave the other end open.

Propaq Encore Service Manual
Section 2-Functional Verification
Functional Verification
note...
Before performing the following steps, convert the percentage of the gas source to
partial pressure (mmHg) according to the procedures in Mainstream CO2
Verification Preparation on page 32.
8. Introduce a flow of test CO2 at a rate of 60 to 200 ml/min into the sensor airway adapter.
9. For test gas calculated partial pressure values of 30 mmHg or less, check the CO2 reading on
the Encore display to be within 3 mmHg.
10. For test gas calculated partial pressure values greater than 30 mmHg, check the CO2 reading on
the Encore display to be within ±10% of the partial pressure value.
note...
If CO2 test results are out of specification limits, check the table on page 38 for
possible error sources. Always verify the test setup to minimize errors.
11. Disconnect the test gas source and other test equipment.
12. Disconnect the CO2 sensor from the monitor.

WARNING
Eliminate all the possibilities causing errors shown in the following table before
performing the calibration procedure in Section 3. Recalibrating the altimeter as
described in Section 3 without adequately eliminating all other possible faults may
result in inaccurate EtCO2 readings.

Cuvette error
Results should not vary more
than 0.5 mmHg due to cuvette
tolerances
Use another cuvette (airway
adapter).
Thermal equilibrium error
Sensor not warmed up
Allow sensor/system to operate
for a 15 minute warm-up period.
High CO2 reading with sensor
subject to room air only
CO2 forced outside of airway
adapter into sensor. This is
possible during demonstration if
exhaled gases are blown through
hands cupped around cuvette
and exhaled gases are forced
into sensor.
Contain exhaled breath through
the inside of cuvette only. Do not
allow gases to be forced outside
of cuvette and into sensor
housing. If CO2 has been forced
into sensor allow 24 to 48 hours
for the CO2 to dissipate.
Sidestream CO2 Verification Procedure
The following procedures verify the operation of the sidestream CO2 (SCO2) option.
1. Allow the monitor to warm-up for 3 minutes before performing the SCO2 tests.
2. If present, disconnect the mainstream sensor from the monitor.

Introduction
Section 3
Calibration
Introduction
This section provides calibration procedures for the Propaq Encore. These procedures allow you to
calibrate the Encore to Protocol factory specifications. Calibrations procedures should be
performed only by qualified service personnel.
Calibration procedures must be performed whenever a question arises as to the performance of
the Encore, and as indicated in Section 1.
Functional verification procedures (see Section 2) verify that the monitor is performing to its
specifications. A functional verification (Section 2) must follow the calibration.
note...
Respiration, temperature, printer, and SpO2 options do not require calibration.
Sidestream CO2 has no user-performable calibration. After replacement of any
modules to support service of these options, perform a functional verification for
those associated modules.
note...
The mainstream CO2 circuitry should be calibrated only if it fails the functional
verification procedure of Section 2 AND you have eliminated all possible faults as
listed in the table Possible Sources of CO2 Verification Test Errors on page 38.

MSP Board (MCO2) Calibration
The Propaq MSP board has two calibration adjustments. One adjustment (RP2) is a null adjust for
electromagnetic interference emissions—this adjustment has no effect on MCO2 performance/
accuracy. The other adjustment (RP1) is a barometric pressure/altimeter setting. This adjustment
is set at Protocol during the production calibration process and does not require readjustment for
use at other altitudes.
note...
The verification section of this manual (Section 2) provides a procedure to verify
MCO2 accuracy. if the verification test results are within specifications, board
calibration is not required. If verification test results exceed specification limits,
RP1 calibration MAY or MAY NOT be required. Before adjusting RP1, check test
parameters as indicated in the Table on page 38 to minimize testing errors.
Determine local barometric pressure as described in Section 2 (on page 32) to
verify Propaq barometer setting. Adjust RP1, if required, as instructed below.
1. From Propaq main menu, push SETUP > MORE > MORE > SERVICE > YES > CO2 TEST >
MAIN TST and observe the displayed barometric pressure. Check that the displayed pressure
is within 3mmHg of the local barometric pressure as calculated in Section 2.
2. Adjust RP1 on MSP board if required to calibrate displayed pressure to specified limits.
3. Using an oscilloscope with a 1X probe, connect probe tip to TP50 on the MSP board. Leave
probe groundtip open.
4. Adjust RP2 for minimum high frequency (100kHz) signal.
WARNING
You must perform a functional verification after calibrating the Propaq Encore to
ensure all monitoring functions and safety features operate normally.

Removing the EL display module may damage the electrically-conductive inner
surface of the display filter. Protocol recommends leaving the display unit in the
front chassis unless you replace the display unit and the front chassis together.
The conductive silicone gasket between the display module and display filter may
remove the delicate coating from the perimeter of the filter if the gasket peels up as
the display module is removed. If electrical contact with the filter is degraded
sufficiently, the display's EMI may interfere with ECG and/or SpO2 monitoring if
patient cables pass near the display.
If you must remove the display module, use two people in the removal procedure to
attempt to minimize damage to the display filter.
This section provides instructions on how to replace the display module. The display module is
attached to the front chassis beneath the Analog and Digital boards by two brackets, each fastened
at the top and bottom by a screw and two washers.
Note the voltage indicated on the label of the display module. This value is used for calibrating the
display high voltage supply on the Recharger board.
1. Remove the battery pack according to the procedures on page 67.
2. Open the monitor according to the procedure on page 71.
3. Remove the Analog board according to the procedure on page 76.

In the next step, if the gasket lifts off the display filter at any point, you must inspect
the display filter to verify that the conductive coating on the filter is still intact. See
the steps below.
6. To carefully remove the display:
• Using a flat blade screwdriver, each person should hold the silicone gasket down where it is
visible between the posts at the top and bottom of the chassis (see figure above).
• With their free hand, each person should gently lift one side of the display module,
attempting to keep the silicone gasket in place on the display filter.
If the gasket lifts off the display filter at any time, inspect the filter beneath the section where the
gasket lifted to ensure the conductive coating around the perimeter of the filter is still intact. Try
not to disturb the rest of the gasket/filter interface as you do this. To inspect the filter, look for a
slight color variation between the perimeter conductive coating and the rest of the filter (see figure
on page 83). (Tilting the front assembly at different angles under a bright light can help you see the
color variation of the conductive coating.) The slight color variation should be continuous around
the perimeter under the gasket. If there is a break in this coating, you must replace the front
assembly with the display filter.

Section 6-Technical Overview
Power Electronics Description
The power system circuits are located on the Analog, Digital, and Recharger boards. The power
system includes the ac mains power adapter. Refer to the figure on on page 125.
The power system
• converts ac mains current to dc current (external power adapter)
• recharges the internal battery pack (Recharger board)
• converts battery power to several voltages for the display (Recharger board)
• converts battery power to several regulated and unregulated power supplies for both isolated
and non-isolated electronics (Analog board)
• provides isolated power for RS423 communications (Digital board)
• controls the activation and deactivation of the power system (Digital board)
Power is delivered from ac mains to the monitor through a power adapter. The adapter converts
ac to dc current at approximately 15 Volts.
The internal battery continually supplies monitor power and is recharged while the power
adapter is plugged into ac mains and connected to the monitor. The monitor can also be recharged
from any dc power source that meets the monitor’s dc power input specifications. An accessory
cable is available from Protocol Systems to allow connection of such a power source to the dc
power input connector on the monitor’s right side panel. This cable must be used for monitor
calibration.
Thermistors in the battery compartment monitor battery temperature. As battery charging takes
place, battery temperature rises. The recharger output voltage is temperature-compensated; as
battery temperature rises, maximum recharger output voltage decreases.
Switching power supplies generate power for recharging the battery, for powering the display,
and for other power sources throughout the monitor. Suppression devices designed into the
power system provide EMI suppression. A transformer bridges the battery power to the isolated
electronics.
Several control lines activate and deactivate the power supplies. These control lines originate on
the Digital board and are routed to the Recharger board and Analog board to activate the display
power supply and the main power supply. The recharger supply is automatically activated any
time an adequate dc power source is connected to the power input jack on the monitor’s right side
panel.

Monitoring Electronics System Description
The monitoring electronics reside on the Analog and Digital boards located in the front chassis
assembly. Refer to the figure on on page 127.
These circuits
• acquire the physiological signals from coupling devices (electrodes, transducers, and probes)
• convert the analog signal to digital data
• process the data for display and alarm monitoring
• display the data and any alarm conditions
• transmits the analog ECG signal across the isolation barrier for real-time analog ECG output
Isolation barriers on the Analog and Digital boards isolate the circuits connected to the patient
from circuits connected to other devices including the monitor’s power input. Communications
and power delivery across the isolation barrier are achieved using opto-couplers and a
transformer rated for medical applications.
Microcontrollers (µCs) control patient data processing, alarm monitoring and display.

NIBP Pneumatics Description
The NIBP (cuff) system:
• inflates the cuff to a target cuff pressure
• converts the cuff air pressure to an electrical signal using a pressure transducer
• deflates the cuff in a controlled manner while the monitoring electronics determines blood
pressure
• protects the patient from cuff over-inflation
The NIBP air system consists of the pump, air valves, transducers, and the cuff. Except for the
primary transducer and cuff, all NIBP pneumatic components are located on the Recharger board.
The pump inflates the cuff only when the bleed and dump valves are closed. These two valves are
normally open to ensure the NIBP tubing does not remain pressurized when the valves are not
energized. The linear valve’s programmable iris determines the cuff inflation and deflation (bleed)
rate.
Two transducers provide redundancy in pressure monitoring to ensure accurate readings and to
ensure cuff deflation in an over-pressure condition. If the cuff pressure reaches the maximum
allowable pressure for the patient class (adult, pede, or neonate), the dump valve opens to quickly
deflate the cuff.
The figures on the following pages illustrate the pressure conditions during a typical NIBP
measurement process.

Expansion Module and Printer Description
Expansion Module and Printer Description
The printer shares battery power with the monitor, but contains its own power supply. The printer
processor communicates with the monitor's processor through the expansion connector and cable.
The Expansion Module is designed to house the Propaq Encore Printer and other circuit boards for
additional parameters. The main circuit board in the Printer is the Printer Main Board. An
additional circuit board (key panel) in the expansion module with printer front chassis contains
the push buttons.
The Printer Main Board is attached to the thermal printer mechanism and should be replaced as a
unit with the printer mechanism if repair is needed.
The Printer Main Board connects to the expansion connector, the battery pack, the push buttons on
the expansion module front panel, the printer mechanism (motor and print head), and the paper
out and head up sensors.
The printer’s microprocessor receives print data and control information from the Propaq Encore
and sends data to the Encore. Communication between the two systems (Encore and printer
CPUs) is done by sending and receiving data packets over serial communication lines.
The print head assembly contains 5 segments consisting of 64 thermal printing dots each for a total
of 320 dots, which cover the width of the paper. As the paper moves under the print head, the
system enables each segment energizing the thermal dots as necessary.
The Printer Main board consists of five functional blocks: Printer CPU, Printer Driver, Printer
Logic, System Power, and Printer Power. These blocks are interconnected by several control lines
and buses. External to the Printer Main board are the key panel, housed in the expansion module
front chassis, and the printer motor and print head, both parts of the printer mechanism.
The Printer CPU block receives data and control information from the Propaq Encore through the
Printer Logic block. The Printer CPU sends data to other printer circuits to control printer
functions and sense printer conditions.
Through the Printer Driver the CPU controls the stepper motor and detects when the paper has
run out.
The CPU loads print data into the Printer Logic block and, through this block, controls the
individual printhead segments. The CPU also interfaces with the Propaq Encore through this
circuitry.
The System Power block provides several dc power supplies to the printer.
The Printer Power block provides the +24V printer power supply.

Pulse Oximetry Option (SpO2) Description
Pulse Oximetry Option (SpO2) Description
The Propaq Encore pulse oximetry option (SpO2) hardware includes two circuit boards, a sidepanel D connector, and related hardware. The pulse oximetry option is installed either in the pulse
oximetry option module attached to the rear of the monitor or in the expansion module when the
printer or the CO2 options are also present.
The two circuit boards include the SpO2 Communications Processor (SCP Board) and the SpO2
Board. The SpO2 Board provides all necessary circuitry to receive and process oxygen saturation
data from the NELLCOR oxygen sensor. The SCP Board prepares the data for processing by the
monitor's processor, and it handles all communications with the monitor. The SCP Board also
drives the SpO2 speaker.
The SpO2 option hardware consists of the following items:
• monitor/option interface circuit board (SCP board)
• SpO2 circuit board
• side-panel connector (9-pin D connector)
• SpO2 speaker
• the SpO2 case attached to the rear of the monitor when no expansion module option is also
present
• in the case of the printer, the expansion module case attached to the bottom of the monitor
The SpO2 signal provided by the oxygen transducer or sensor is first processed by the SpO2 circuit
board where it is converted to digital data, then that data is passed to the SCP board where it is
prepared for transmission to the Propaq Encore monitor's main microprocessor.
An SpO2 option isolated power supply, powered by monitor batteries, resides on the SCP board,
supplying power to the SpO2 circuits only. If the SpO2 option is part of the expansion module, the
SpO2 power supply does not provide power to the printer in the expansion module. The printer
circuit board provides power to the printer.
A connector on the side panel allows connection of an oxygen transducer (to the 9-pin D-type
connector) directly to the Propaq Encore.
The NELLCOR oxygen transducer senses oxygen content of functional arteriolar hemoglobin
through the use of light passed through the sensor site. The reflective/absorbative characteristics
of hemoglobin at the wavelengths used allow the pulse oximetry circuits to obtain changing
saturation levels, which can be processed to obtain the oxygen saturation percentage.
Wavelengths in the red and the infrared regions of light are produced by light emitting diodes
(LEDs) manufactured to emit light at the required wavelengths. The reflected light is detected by a
photo diode, which converts the light to an electrical signal. The LEDs are switched on and off
under control of the SpO2 microprocessor. Both are not on at the same time. As the system receives
the signal from the photo diode, it knows whether the signal was derived from the red or infrared
LED. Because the photo diode is sensitive to light emitted from sources other than the LEDs
(ambient light), an ambient light component is subtracted from the signal during the processing of
the SpO2 data.
An internal calibration resistor in the transducer is used to identify the wavelengths of light
produced by the LEDs. This information is required for proper processing of the SpO2 data.
Protocol Systems, Inc.
137
Pulse Oximetry Option (SpO2) Description
Section 6-Technical Overview
note...
The oxygen transducers are not serviceable units.
The figure on on page 139 shows a functional block diagram of the SpO2 circuit board. The SpO2
board consists of the following subsystems:
• internal preamplifier and switch
• ac-coupled amplifier
• inverting amplifier with variable gain stage
• synchronous detector
• splitter
• 5-pole low pass filters
• 16-bit ADC
• internal calibration amplifier
• CPU/Control
• LED current drivers
• compare amplifiers
The CPU detects the presence of a transducer plugged into the D-type connector. Switch S1 routes
the signal from the preamplifier to the ac-coupled amplifier. The input signal is ac-coupled to
remove any dc offset present. The result is a pulse waveform representing light levels from three
sources: red LED, infrared (IR) LED, and ambient. An inverting amplifier with a variable gain
stage scales the signal to allow processing the best available pulse oximetry information.
Because the CPU controls the LEDS in the sensor, it knows which pulse level of the input
waveform represents which wavelength of light. When the red LED is activated, the waveform
level indicates red light plus ambient light. When the IR LED is activated, the waveform level
indicates IR light plus ambient light. When neither LED is activated, the waveform level indicates
ambient light. Only the detected red and IR light levels are used to determine the SpO2 saturation
value. The synchronous detector inverts the ambient light signal so that the ambient light signal
can be subtracted from the red plus ambient light signal and the IR plus ambient light signal.
The pulses are filtered through 5-pole filter networks to remove the signal components above
about 20Hz. The resulting signals indicate the detected RED and IR light levels and can then be
digitized. The data from the ADC is processed by the CPU and then sent to the SCP board for
transmission to the Propaq Encore monitor's CPU.
SpO2 signal level is controlled through the variable gain stage of the inverting amplifier and the
output current of the LED current driver. By controlling both signal gain and current drive, the
CPU can maintain the best possible signal level for processing. Amplifiers sense the SpO2 signal
levels at two points, directly sending their outputs to the CPU. The CPU monitors these levels as it
sets the gain stages of the inverting amplifier and LED current driver.

Capnography (CO2) Description
Section 6-Technical Overview
Capnography (CO2) Description
Two capnography (CO2) monitoring options are available—the mainstream -sampling CO2 option
(MCO2) and the sidestream-sampling CO2 option (SCO2).
Both mainstream CO2 and sidestream CO2 options are available in one product. However, only
one sampling method may be monitored at any time—simultaneous monitoring of MCO2 and
SCO2 is not supported.
The mainstream CO2 circuit board (MSP) supports all mainstream and Sidestream applications
and is the major interface between the printer and SpO2 hardware in certain configurations of the
Expansion Module. The MSP board replaces the SCP board in SpO2 applications with CO2. For
sidestream-only applications, an MSP board version without mainstream hardware is used. For
both mainstream and sidestream applications, the MSP board is mounted within the rear panel of
the Expansion Module housing.
Mainstream CO2Option. In the mainstream sampling method, the CO2 analysis chamber
(commonly referred to as the “bench”) is an integral part of the mainstream sensor which is
located in-line, between the patient’s airway and the ventilator circuit via an airway adapter. The
patient’s expired gas is sampled directly from the patient’s airway. The MSP board interfaces the
external mainstream sensor to the Propaq monitor.
Sidestream CO2 Option. In the Sidestream sampling method, the bench is located on the Stick
board within the Propaq monitor. A sample of the patient’s expired gas is aspirated from the
airway and is drawn to the bench through a sampling line containing a water trap. The Stick board
also contains pneumatic tubing that connects to the SSP board. The Stick board is mounted on the
Sidestream Processor board assembly (SSP board) which interfaces the Stick board to the Propaq
monitor. The SSP/Stick board assembly is mounted within the front bezel of the Expansion
Module housing of the Propaq monitor.
System Interface. The SSP board power and communication is obtained via the extender board
that connects to the MSP board. The extender board routes datalines from the MSP board and
contains additional power supplies for powering the SCO2 boards.
The Main Stream Processor circuit board (MSP board) is the major interface connection between
several subsystems in the Expansion Module. This circuit board connects directly to the expansion
connector, providing a direct interface to a Propaq Encore Display Processor system.
The MSP board also supports:
• Main Stream CO2
• an interface to the SpO2 system
• an interface to the Printer option
• an interface to sidestream CO2

Section 6-Technical Overview
Capnography (CO2) Description
Mainstream Board
The MSP board is divided into isolated and non-isolated circuitry. See the figure below.
Non-Isolated Circuitry. The Non-Isolated circuitry on the MSP board interfaces with the
Propaq Encore, the printer, the speaker, P6 and P7 expansion connectors, and with the Main
Stream Processor which resides on the isolated section of the MSP board.
Isolated Circuitry. The Isolated Circuitry directly controls the hardware responsible for the
CO2 measurement function.
CPU Circuitry. The CPU Circuitry includes the Philips 80C552 micro controller, 32K of RAM,
64K of ROM, and standard RESET circuitry.
A UART directly interfaces with the Nellcor SpO2 board providing the SpO2 measurement
function.
The CO2 and SpO2 functions are isolated from all other subsystems in the Propaq Encore or
Expansion modules, but not from each other.

Capnography (CO2) Description
Section 6-Technical Overview
IPC Expansion
The Inter-processor Communications (IPC) bus, originating in the Propaq Encore, is passed to the
MSP board from the expansion connector. The two-wire bus is expanded to the printer and to the
Main Stream Processor via opto-couplers.
Power Distribution System
Power for CO2 and SpO2 circuit operations is derived solely from the expansion Connector. The
principal supply comes from the Propaq Encore battery connections and an on-board switching
power supply.
CO2 Analysis Chamber (Bench)
Analysis of the expired CO2 occurs in the bench. The bench is located in the mainstream sensor for
MCO2 or on the sidestream stick board for SCO2.
In mainstream applications, the sensor mounts over, and connects to, a disposable airway adapter
(cuvette) through which the patient’s exhaled gases flow. In sidestream applications, a sample of
exhaled gases is obtained through a small diameter sampling tube and routed to the bench located
on the Stick board.
Unless otherwise noted, the following details are common for bench operation in both sampling
methods.
The bench consists of infrared (IR) light source and filter, a revolving chopper wheel, and a
photodetector.
The chopper wheel is an aluminum disk containing a sealed CO2 reference cell, an open slot, and a
light-blocking area. The chopper wheel spins in the direct path of the IR light source.
The IR source is located on one side of the bench and is projected through the gas sample (in the
airway adapter in MCO2; routed directly to the bench in SCO2) to a photodetector at the other side
of the bench. As the IR beam passes through the gas sample to the photodetector, the components
of the spinning chopper wheel are passed through the beam with each revolution.
The amplified photodetector output signal is modulated by the revolving chopper wheel and is
referred to as VSIG. Each rotation of the chopper wheel generates two VSIG peaks of differing
size, and a low flat spot. The voltages representing these points are called Vpeakhi, Vpeaklo, and
Vdark. These correspond to the open slot, the CO2 reference cell and the light blocking areas on
the chopper wheel, respectively. The VSIG output from each complete rotation of the bench
chopper wheel, occurring every thirty milliseconds, together with a known bench temperature
and calibration constants stored in an EEPROM (located in the mainstream sensor connector or
the sidestream Stick PCB), provides all required information to determine the CO2 value.

Appendix B-Dynatech/Nevada Patient Simulator Modification
Introduction

Dynatech/Nevada
Patient Simulator
Modification
Introduction
The factory configuration of the Dynatech/Nevada model 214A, 215A, and 217A Patient
Simulators is incompatible with the Propaq Encore monitors with IBP channels when both the
ECG and invasive pressure simulator channels are simultaneously connected to the monitor.
Erroneous readings result. The patient simulator must be modified as described in this appendix
in order to use both simulator channels with the Propaq Encore monitors with IBP. If only one
simulator channel is used, the modification is unnecessary.
Modify the patient simulator's invasive pressure cable as shown in the figure below.
