Capnometry Waveform Analysis

Capnometry waveform analysis refers to the continuous monitoring and interpretation of the carbon dioxide (CO2) concentration waveform displayed during capnometry, a non-invasive method used by EMS providers to assess ventilation status. This waveform provides real-time information on the patient’s respiratory cycle and can indicate airway patency, ventilation adequacy, and metabolic activity. Not to be confused with simple numeric end-tidal CO2 values, waveform analysis is essential during advanced airway management and supports patient monitoring in environments requiring SCBA or during critical care transport.
