Monitor configuration
1. Configure the CO2 waveform field to the monitor screen with adequate priority.
2. Select CO2 Setup tab in
Gases
menu and configure:
FiO2 level : 21-40%
3.3.2 Procedure
1. Gas sampling system leak test
Check the gas sampling system for possible leakages.
a. Disconnect the module from the monitor.
b. Connect a new Mini D-fend water trap to the module.
c. Connect a new gas sampling line to the sampling line connector in the water trap.
d. Connect the other end of the gas sampling line to a pressure manometer and a
pressure pump.
e. Block the "Sample Gas Out" connector.
f. Pump 100 mmHg ± 20 mmHg pressure to the gas sampling system. Let the pressure
stabilize for approximately 10 seconds.
g. Check that the pressure reading does not drop more than 6 mmHg during 1 minute.
NOTE: The gas module shall be disconnected from the monitor during the leak test.
2. Sample flow check
Check the sample flow rate.
NOTE: Gas measurement is not available during the first 1 minute after the module is
connected due to warm-up. Message 'Calibrating Gas Sensor' is shown in the waveform field.
Wait until warm-up is completed before proceeding with the next steps.
NOTE: The ambient temperature and air pressure influence the flow rate measured by the flow
meter. A flow meter, which has been calibrated at 21.1
°
C (70
°
F) and 760 mmHg (1013 mbar),
measures the flow rate correctly under the same conditions, i.e. in room temperature at sea
level. A flow rate correction as instructed by the manufacturer of the flow meter needs to be
performed when measuring flow rate under other conditions, for example in high altitude.
a. Connect the module with the gas sampling line to the monitor.
b. Connect the gas sampling line to the sampling line connector in the water trap.
c. Connect the other end of the gas sampling line to a flowmeter.
d. Check the sample flow rate reading from the flowmeter. The flow rate shall be within
the specification limit 150 ± 25 ml/min.
NOTE: Readjustment is needed, if the measured value is not within the specification limits.
Adjust the sample gas flow rate according to the instructions in section
4.1.2. Sample flow rate
adjustment .
NOTE: If the sampling pump is noisy it indicates possible problems with motor bearing. In this
case it is recommended to replace the noisy sampling pump with a new one.
3. Zero valve operation
Test the zero valve functionality.
a. Connect the gas regulator to the calibration gas container.
