The sampling line of at least
one out of the airway
pressure sensor and PEEP
pressure sensor is not
connected or is connected
improperly. Refer to
5.4Troubleshoot
Sensor and
Valve Related Failures by
Using the Valves-test Tool
.
Re-connect the sensor sampling
line.
The maximum pressure
which the PEEP valve
produces is less than 95
cmH2O. Refer to
5.4Troubleshoot
Sensor and
Valve Related Failures by
Using the Valves-test Tool
.
Replace the expiratory valve
assembly.
After [

1. Check the pneumatic circuit
connection between the
anesthesia machine calibration
device and the monitor board.
Re-connect the pneumatic
circuit if necessary.
2. Check the communication
connection between the
anesthesia machine calibration
device and the anesthesia
