when initially connecting to the CO
2
module and whenever there is a change in the
conditions at the patient airway.
In the CO
2
module, the temperature of the gas in the airway also effects the CO
2
measurement. It is necessary to adjust the instrument setting for the gas temperature to
achieve the maximum accuracy for the CO
2
module.
OXYGEN COMPENSATION
The setting range is 0～100 %. The factory setting is 16 %.
BALANCE GAS
There are Room Air, N
2
O and Helium items to choose. The factory setting is Room Air.
ANESTHETIC AGENT
Use this setting to correct for the compensation of the gas mixture administered to the
patient. Anesthetic agent is ignored when the balance gas is set to helium.
The setting range is 0.0～20.0 %. The factory setting is 0.0 %.
BAROMETRIC PRESSURE
This setting is used to set current Barometric Pressure.
The setting range is 400～850 mmHg. The factory setting is 760 mmHg.
GAS TEMPERATURE
This setting is used to set temperature of the gas mixture. This setting is useful when
bench testing using static gasses where the temperature is often room temperature or
below.
The setting range is 0～50 ℃. The factory setting is 35 ℃.
CALIBRATION
No routine user calibration required.
Safety lock-outs:
 System does not allow sample cell zero for 20 seconds after the last breath is
detected.
 System does not allow sample cell zero if temperature is not stable.
 An adapter zero cannot be performed if a sample cell is not connected to the
module.
[NOTE]: At 700 mmHg of pressure, the correct CO
2
value is 35.0 mmHg.
