Equipment

Equipment employed in end-tidal capnography includes the following:

  • End-tidal capnometer (fixed or portable)
  • Mainstream or sidestream sampling (see  End-Tidal CO2 Detectors)
  • Nasal cannula or mask adaptors (nonintubated patients)

The end-tidal capnometer must be prepared, calibrated, and tested prior to use. (See the image below).

Patient Preparation

The patient should be in a position that both facilitates airway patency and allows adequate exposure for the procedure being performed. Often, the anesthesia provider and the surgeon discuss which technique and position will minimize risks to the patient prior to the procedure. Ideally, if endotracheal intubation is indicated, the patient is placed in a supine position for induction of general anesthesia and airway management.
