Capnography in prehospital trauma care is primarily used to:

Capnography tracks end-tidal CO2 and provides a real-time waveform, giving you direct feedback on ventilation and airway status. In prehospital trauma care, this is crucial because it lets you confirm that air is actually moving into and out of the lungs and that an airway device is correctly positioned. A normal or expected end-tidal CO2 value with a measurable waveform indicates adequate ventilation and proper airway management; a sudden loss of waveform or a drop in EtCO2 signals problems such as airway obstruction, tube dislodgement, or poor ventilation, prompting immediate reassessment. While capnography is valuable for monitoring ventilation, oxygen saturation and blood pressure require separate measurements (pulse oximetry for SpO2 and a cuff or monitor for BP).
