7.3 Use a Mainstream CO
2
 Module 
 
NOTE 
  This section is only applicable to the ventilator configured with mainstream CO
2
 
module. 
 
7.3.1 Prepare to Measure CO
2
 
1.  Connect the sensor to the CO
2
 module. 
2.  By default, the mainstream CO
2
 module is in measure mode. The [CO
2
 Warm-up] 
message appears on the screen when the CO
2
 module is switched on (CO
2
 sensor 
monitoring is set to ON). 
3.  After warm-up is finished, connect the sensor to the airway adapter. 
4.  Perform a zero calibration, referring to 7.3.4 Zero the Sensor   
5.  After the zero calibration is finished, connect the airway as shown below. 
 
 
 
5.  Ensure that there are no leakages in the airway, and then perform CO
2
 measurements. 
 
WARNING 
  Always ensure the integrity of the patient breathing circuit by verifying a proper 
CO
2
 waveform on the ventilator display after insertion of the airway adapter. 
  If the CO
2
 waveform appears abnormally, inspect the CO
2
 airway adapter and 
replace it if needed.
