Is measurement of end tidal CO2 through a nasal cannula reliable?
Is measurement of end tidal CO2 through a nasal cannula reliable? Abstract. When using a nasal cannula to sample gases expired by a patient, air from the room may dilute the sample. For this reason, the accuracy of the partial pressure of end-tidal carbon dioxide (ETCO2) measurements is questionable. How do I monitor ETCO2? Capnometry […]
