5.1 Adjustments and calibrations
5.1.1 Calibrating
The airway module should be calibrated once every six months or whenever there are
indications of errors in the gas readings.
Calibrate the gas measurement with the Datex-Ohmeda calibration gas. Do not use any other
calibration gases.
−
Use the regulator 755534.
−
Use gas 755580 only and set the FiO2 level in the CO2 setup menu to 21-40% Airway Gas
- CO2 setup. .O
2
concentration to 20%.
Use only recommended calibration gases to guarantee a successful calibration.
During gas calibration, % units are always used for CO
2
regardless of selected measuring units.
NOTE: Ensure that the calibration gas and regulator are functioning properly before calibration.
Perform the annual maintenance on the regulator as required.
Figure 8 Attaching regulator to the calibration can
1. Attach the regulator to the gas container.
2. Attach a new sampling line to the water trap. Connect the loose end of the sampling line
to the regulator on the gas container.
