This chapter describes how to monitor carbon dioxide (CO
The carbon dioxide monitoring function of the Efficia DFM100 measures the partial pressure of
carbon dioxide in a sample of the patient's exhaled breath. The Efficia DFM100 may be used to
monitor carbon dioxide in both intubated and non-intubated patients.
The partial pressure of carbon dioxide is derived by multiplying the measured carbon dioxide
concentration with the ambient pressure. From the partial pressure measurement, the end-tidal
