Choosing Measured AWV Components
1 In the Setup Spirometry menu, select AWV.
2 Select MV to choose the measured components for Minute Volume (inspiratory and/or expiratory
or off).
Select
TV to choose the measured components for Tidal Volume (inspiratory and/or expiratory or
off).
NOTE
If MV and TV are set to off, there will be no alarming for these parameters.
Setting the Gas Compensation Mode
1 In the Setup Spirometry menu, select Gas Compensation.
2 Select Mode to choose the Gas Compensation mode:
– select
Manual for manually entered gas concentrations or
– select
Gas Analyzer for gas concentrations from the gas analyzer.
NOTE
• Gas concentrations from the gas analyzer are only available for Philips gas analyzers, not for
devices connected via a Vuelink/IntelliBridge module.
• If gas concentrations from the gas analyzer are selected but not all data is available, the missing
data is taken from manually entered values. In case of invalid data or no data at all, the INOP
message
Spiro Gas Compens? is displayed.
Changing the Type of Balance Gas
1 In the Setup Spirometry menu, select Gas Compensation.
2 Select Balance Gas to change the type of balance gas.

.
Select
Inspired Agent to change the concentration of the inspired agent(s).

Changing the Temperature of the Inspired Gas
Depending on the type of ventilator environment (e.g. if you are using a Heat Moisture Exchanger)
you may want to change the temperature setting of the inspired gas:
1 In the Setup Spirometry menu, select Gas Compensation.
2 Select Inspired Temp to change the temperature of the inspired gas.
3 Select the appropriate temperature setting.
NOTE
Changing the temperature setting unintentionally will result in approximately 3% reduced accuracy per
10°C (18°F) temperature setting change.
