Capnography is a technique for continuously monitoring the carbon dioxide content of expired air. It is particularly useful in field and emergency medicine, to verify proper positioning of airways and effectiveness of artificial respiration, and for patient monitoring during anesthesia.

The technique complements blood gas analysis by focusing on the actual gas exchange rather than carbon dioxide in blood. Like pulse oximetry, it is a relatively noninvasive technique.
