Troubleshooting
3. Check the vaporizer setting.
4. Continuously monitor the O
2 flow of the emergency delivery.
Take the following measures if necessary:
► Perform the ventilation with ambient air. For further information see: "Complete
failure of the gas supply", page 193.
► Ventilate the patient with the manual resuscitator.
12.5 Failure of the piston ventilator
If the ventilator fails, only manual ventilation or spontaneous breathing remain
possible. No other ventilation modes can be selected. The fresh-gas delivery
remains ready for operation.
1. Switch to the Man/Spon ventilation mode.
2. Ventilate the patient manually.
12.6 Failure of the O2 sensor
If the O2 measurement not available alarm is displayed, the O2 measurement has
failed.
1. WARNING
Risk due to faulty O2 sensor
If the O
2 measurement fails, it will no longer be possible to monitor the patient
adequately.
► Make sure that substitute O
2 monitoring conforming to the general safety
requirements is available.
Perform a system test and calibrate the O
2 sensor.
2. If the calibration fails and the O
2 sensor failure alarm is displayed, refer to the
following table:
Cause Remedy
During the calibration, the sensor was
exposed to a gas mixture with a fluctu-
ating O
2 concentration.
The O
2 sensor was not correctly
placed.
The O
2 sensor was placed close to
mobile radio equipment or similar
sources.
During calibration:
– Remove the sensor from the breath-
ing system and place it on the work
surface.
– Do not fill vaporizers during the cali-
bration.
– Close the additional O
2 flow delivery
for the fresh gas mixer.
– Do not blow into the sensor.
– Do not use any disinfectants.
– Close off other gas sources in the
vicinity of the sensor.
