13.4.4 Setting up CO
2
Compensations
WARNING
z
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, in the [
CO2 Setup
] menu, respectively select:
„ [
O2 Compen
] and toggle between [
On
] and [
Off
]. When the amount of O
2
in the
ventilation gas mixture is greater than 50%, you’d better switch this compensation on.
„ [
N2O Compen
] and toggle between [
On
] and [
Off
]. When the amount of N
2
O in the
ventilation gas mixture is greater than 30%, you’d better switch this compensation on.
„
[
Des Compen
] and toggle between [
On
] and [
Off
]. If desflurane is present in the
ventilation gas mixture, you’d better switch this compensation on.
For the microstream CO
2
module, gas compensations are not required.
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.
„ [
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.
13.4.5 Humidity Compensation for Side/Microsctream CO
2
Readings
Sidestream and microstream CO
2
modules are configured to compensate CO
2
readings for
either Body Temperature and Pressure, Saturated Gas (BTPS), to account for humidity in the
patient’s breath, or Ambient Temperature and Pressure, Dry Gas (ATPD).
1. In the [
CO2 Setup
] menu, select [
Humidity Compen
].
