Monitoring End-Tidal CO2
Introduction
Overview
End-tidal CO
2
monitoring is a continuous, non-invasive technique that determines the
concentration of carbon dioxide in respiratory gas by measuring the absorption of
specific wavelengths of infrared light.
The light generated in the analyzer bench is passed through respiratory gas. The
amount of absorption by CO
2
is measured and digitized by the photodectector. The
monitor processed the electrical signal and displays a parameter window and a
waveform.
773A
It may take up to two minutes after the sensor is connected to the monitor to display
patient data and a waveform. The message “
WARMING UP ” displays in the CO
2
parameter window and is replaced with patient data when available. The display
updates every two seconds.
Compatible Devices/Sensors
Patients can be monitored whether intubated or non-intubated.
„ Intubated patients — Use the SAM module or a direct connection to the CO
2
patient connector on the monitor.
„
Non-intubated patients — Use the CapnoFlex LF CO
2
module.
