End-tidal carbon dioxide physiology and monitoring during resuscitation

Research output: Contribution to journalReview articlepeer-review


This article discusses the measurement, physiology, and clinical use of end-tidal CO2, especially during low blood flow states. End-tidal CO2 concentration depends on both pulmonary blood flow and minute ventilation. CO2, if present, is helpful in confirming tracheal intubation, even in cardiac arrest. Poor blood flow during CPR is associated with a low end- tidal CO2 concentration and a poor chance for resuscitation and survival from cardiac arrest. The limitation of end-tidal CO2 monitoring is that levels are affected by perfusion, ventilation, and CO2 production.
