Troubleshooting
12.6.1 Failure of the integrated patient-gas measurement module
(PGM)
► WARNING
Risk due to gas measurement failure
If the gas measurement fails, the patient can no longer be adequately
monitored.
► Check the sample line and the water trap for damage or blockages. Pay
attention to the replacement intervals.
► Replace the patient-gas measurement module.
► Ensure corresponding substitute monitoring.
Arrange for appropriate substitute monitoring conforming to ISO 80601-2-55.
12.6.2 Replacing the patient-gas measurement module (PGM)
Contact service personnel to replace the PGM.
Prerequisite:
– There is no patient connected.
– The device is switched off.
– The device is disconnected from the power supply. To do this, disconnect the
power plug.
– The water trap has been removed.
1. WARNING
Incorrect gas measurement
Faulty or non-functional PGMs can cause incorrect gas measurements. As a
result, the patient could be put at risk.
► Have the PGM replaced by service personnel.
The O
2 sensor cell is not present or is
not plugged in correctly.
Check the O2 sensor cell:
– Insert the sensor cell if it is not pres-
ent.
– Check that the sensor cell is cor-
rectly seated.
– Calibrate the sensor cell again.
An initialization phase of up to 30
minutes is required after a new O

possible once more.
The O
