17 CO2 Monitoring
17.1 Overview
The monitor is able to measure the CO2 pressure of the patient airway, and displays the CO2
waveform in the waveforms area of the monitor screen. The CO2 parameter window shows
the following parameters:
•
End-tidal CO2 concentration (EtCO2)
•
Inspired Minimum CO2 (InsCO2)
•
Air Way Respiration Rate (AwRR)

Waveform name
1.
CO2 label: This option allows you to access the CO2 SETUP menu.
2.
Pressure unit: mmHg or kPa.
3.
EtCO2: The measured value of EtCO2.
4.
InsCO2: The measured value of InsCO2.
5.
AwRR: The measured value of AwRR.
Adverse effects on stated perfomance may occur as a result of the following:
•
Leaks or internal venting of sampled gas;
•
Mechanical shock;
•
Cyclic pressure up to 10 kPa (100 cmH2O);
•
Other sources of interference, if any.
NOTE
•
CO2 and CO2 are used interchangeably in this chapter.
•
The sidestream CO2 module is equipped with automatic barometric pressure
compensation.
