Capnometry Waveform Analysis

What Is 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.

Why Capnometry Waveform Analysis Matters on the Fireground

Understanding capnometry waveforms enhances patient assessment accuracy, enabling early detection of respiratory compromise or tube dislodgement. This critical feedback supports EMS decision-making and patient safety during interventions, consistent with protocols like PAR (Personnel Accountability Report) and MAYDAY calls when airway emergencies arise.
