2 Set »Pmax« knob to 60 mbar initially.
3 Set »PEEP« knob to 0 mbar* initially.
4 Use the mixer switch to set the required O

or
No Air Mix = 100 vol.% O
In air mix mode, the applied tidal volume V
reduced in case of high airway pressure, due to the
physical properties of the injector used for mixing.
Increase the tidal volume V
measured minute volume MV.
5 ON/OFF switch set to I.
Display:
Self test
SW-version xx.xx
When the patient is connected:
Check the minute volume MV displayed and adjust
settings to suit the patient.
The following display appears if the expiratory minute
volume is less than 1 L/min:
IPPV MV = 0
6 Read off the maximum airway pressure Paw on the
pressure gauge.
2 Set »Pmax« knob to approx. 10 mbar higher than the
maximum airway pressure.
If the airway pressure in the range of settings between
20 and 60 mbar exceeds the maximum airway pressure
»Pmax«, the machine immediately switches over to
expiration to protect the patient and displays the warning
message:
Paw high
The set tidal volume V
