Troubleshooting
Calibrate flow sensor!
The flow sensor must be cali-
brated after the device is
switched on and after a mains
power supply failure.
Press the
OK
key and calibrate
the flow sensor, see page 95.
The flow is not measured until
the sensor has been calibrated.
To work without flow measure-
ment, press only the
OK
key.
Check PEEP setting!
The
PEEP/CPAP
setting knob
determines the mean airway
pressure during high-frequency
ventilation.
After high-frequency ventilation is
terminated, set
PEEP
to the
desired value using the
PEEP/CPAP
setting knob.
