Capnography values help confirm what during prehospital trauma care?

End-tidal CO2 readings show how effectively a patient is being ventilated. In prehospital trauma care, capnography provides real-time feedback on ventilation and airway status. A consistent ETCO2 waveform indicates air is reaching the lungs and ventilation is adequate for the current settings. It also helps confirm airway management, especially after intubation, because a proper CO2 waveform confirms tracheal placement; an absent or significantly altered waveform can signal esophageal intubation or airway obstruction so you can correct promptly. Trends in ETCO2 can reflect perfusion changes during resuscitation, offering a dynamic view of the patient’s status. Capnography does not measure oxygen saturation—that’s pulse oximetry—and it is routinely used in prehospital care to guide ventilation decisions.
