Qualitative and quantitative measurement of the carbon dioxide (CO2) concentration in respiratory gases is readily available with current technology. End-tidal CO2 (PetCO2) monitoring, whether by qualitative colorimetric methods or by solid-state spectrophotometric techniques, is becoming increasingly valuable in the Emergency Department (ED). These techniques offer a practical adjunct to the ED management of critical interventions including endotracheal intubation, conscious sedation, and cardiopulmonary resuscitation.
