The monitoring of end-tidal carbon dioxide (ETCO2) is not a new practice, having been introduced to the United states in 1978. It is a modality where clinical application in critical care environments has been sporadic and plagued by the initial inadequacies of the technology. The critical care educator, manager, or advanced practice nurse can assist in identifying myths in practice and educate colleagues on the principles and application of capnography.
