A call for standards on perioperative CO(2) regulation.

Publication Date Feb 8, 2011

Abstract

To The Editor, The Journal recently published the International Standards to the Practice of Anesthesia. These Standards mandate the use of capnography, but they fail to provide guidelines for carbon dioxide management. Except under rare circumstances, carbon dioxide is inert, odourless, tasteless, invisible, and remarkably benign and beneficial. It is heavier than other atmospheric gases, so it accumulates in dependent locations, such as mines, where air circulation is lacking. Under these conditions, it displaces oxygen and causes death by drowning. Since this phenomenon was attributed to toxicity in earlier times and early gas research confused CO2 effects with carbon monoxide toxicity, carbon dioxide remains widely but mistakenly feared as toxic and narcotic. All vertebrate cells produce CO2 continuously. It saturates body tissues and fluids, and it equilibrates with the external environment. Carotid and aortic respiratory chemoreceptors gradually adapt to and maintain this equilibrium. Synergistic combinations of hypercarbia and hypoxemia exponentially increase chemoreceptor activity and respiratory drive. Hyperventilation is unnatural and abnormal in all circumstances. It confers no tangible benefits, and it may cause serious adverse events, including ‘‘shallow water blackout syndrome’’, brain damage in mountain climbers, and increased morbidity and mortality in otherwise healthy polio victims. Nowadays, its traditional use to counteract brain swelling is discouraged. Mechanical hyperventilation rapidly depletes CO2 ti...
