carbon monoxide poisoning
Also written as: CO
Systemic toxicity from inhaling carbon monoxide gas, commonly associated with fire exposure.
Full Definition
A potentially life-threatening condition resulting from inhalation of carbon monoxide (CO), a colorless, odorless gas produced during incomplete combustion. Carbon monoxide has an affinity for hemoglobin approximately 200 times greater than oxygen, forming carboxyhemoglobin and severely compromising oxygen delivery to tissues. In burn patients, CO poisoning often accompanies inhalation injury and requires immediate treatment with high-flow oxygen or hyperbaric oxygen therapy.
Usage
Usage note: Often abbreviated as CO poisoning; distinguish from cyanide poisoning which may also occur in fires.
