NOTE

Always position the sensor with the adapter in an upright position to avoid collection of fluids on the
windows of the adapter. Large concentrations of fluids at this point will obstruct gas analysis.
15.4 Changing CO
2
Settings
15.4.1 Setting the CO
2
Unit
Select [ Unit Setup >> ] from the [ User Maintenance ] menu. In the popup menu, select [ CO2 Unit ] and toggle between
[ mmHg ], [ % ] and [ kPa ].
15.4.2 Accessing CO
2
Menus
By selecting the CO
2
parameter window or waveform, you can access the [ CO2 Setup ] menu.
15.4.3 Setting up Gas Compensations
WARNING

Make sure that the appropriate compensations are used. Inappropriate compensations may cause
inaccurate measurement values and result in misdiagnosis.
For the sidestream CO
2
module:
1. Select [ CO2 Setup ].
2. According to the actual condition, set the concentration required for the following compensations:

[ O2 Compen ]

[ N2O Compen ]

[ Des Compen ]
For the mainstream CO
2
module, in the [ CO2 Setup ] menu, respectively select:

[ Balance Gas ] and toggle between [ Room Air ] and [ N2O ]. Select [ Room Air ] when air predominates in the
ventilation gas mixture and select [ N2O ] when N
2
O predominates in the ventilation gas mixture and select [ He ]
when He predominates in the ventilation gas mixture.

[ O2 Compen ] and then select [ Off ] or an appropriate setting according to the amount of O
2
in the ventilation gas
mixture. When the amount of O
2
is less than 30%, you’d better switch this compensation off.

[ AG Compen ] and enter the concentration of anesthetic gas present in the ventilation gas mixture. This could
compensate for the effect of AG on the readings.
For the microstream CO
2
module, gas compensations are not required.
