Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - The cellular asphyxiants are a diverse group of substances including carbon monoxide (CO), cyanide, sodium azide, methemoglobin-producing oxidizing agents, and hydrogen sulfide, all of which interfere with the cellular utilization of oxygen. Depending on the substance, the interference may occur at the level of hemoglobin, the electron transport chain, or both. In contrast with the simple asphyxiants, ambient oxygen concentrations are not affected.
