Capnography

24 minutes

In this episode of EMTprep Pulse Check, we explore capnography and the important information it provides about a patient's ventilation and respiratory status. Listeners will learn what end-tidal carbon dioxide (EtCO₂) represents, how capnography helps evaluate ventilation, and how changes in capnography readings can provide important clues about a patient's condition.

The episode connects capnography to practical EMS assessment and patient care, emphasizing its value in monitoring respiratory patients, evaluating ventilation, and recognizing changes in a patient's clinical status. By understanding the basics of EtCO₂ and capnography, EMTs can improve their ability to assess respiratory function and identify potentially life-threatening problems.
