15.8 Troubleshooting the Sidestream CO
2
Sampling System
When the sampling system of the sidestream CO
2
module works incorrectly, check if the sampling line is kinked. If not,
remove it from the watertrap. If the monitor gives a message indicating the airway still works incorrectly, it indicates that
the watertrap must have been blocked, and you should replace with a new one. Otherwise, you can determine that the
sampling line must have been blocked. Replace with a new sampling line.
15.9 Removing Exhaust Gases from the System
WARNING

Anesthetics: When using the Sidestream or Microstream CO
2
measurement on patients who are receiving or
have recently received anesthetics, connect the outlet to a scavenging system, or to the anesthesia
machine/ventilator, to avoid exposing medical staff to anesthetics.
To remove the sample gas to a scavenging system, connect an exhaust tube to the gas outlet connector of the module.
15.10 Zeroing the Sensor
The zero calibration eliminates the effect of baseline drift during CO
2
measurement exerted on the readings and
therefore maintains the accuracy of the CO
2
measurements.
15.10.1 For Sidestream and Microstream CO
2
Modules
For sidestream and microstream CO
2
modules, a zero calibration is carried out automatically when necessary. You can
also start a manual zero calibration if necessary.
To manually start a zero calibration:
1. Select [ Main Menu ]
→
[ Maintenance >>]
→
[ User Maintenance >>]
→
enter the required password
→
[ Maintain
CO2
>>].
2. Select [
Calibrate CO2
>>]
→
[
Start Zero Cal.
].
Disconnecting the patient airway is not required when performing a zero calibration.
15.11 Calibrating the Sensor
For sidestream or microstream CO
2
modules, a calibration should be performed once every year or when the readings go
far beyond the range. For details, refer to the chapter 23 Maintenance .
