all machines. The inclusion of the remaining settings depends on the
purchased features for the specific machine.
Set the altitude
The accuracy of some of the ventilator measurements is altitude sensitive. To
ensure the specified accuracy, the altitude setting should be set to the specific
altitude where each machine is located.
Altitude settings range from -400 to 3600 meters in increments of 100 meters.
The setting is saved in EEPROM; the default value is 300 meters.
Select drive gas
Either O

or Air can be used as the drive gas for the ventilator’s pneumatic
engine.
To compensate volume calculations for the specific density of the drive gas
used, the drive gas selection on this menu must match the actual drive gas.
To change the actual drive gas, refer to Section 4 of the respective anesthesia
machine Technical Reference Manual.

Caution If you change the drive gas, you must also change the drive gas selection
