Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. [3] Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. [1] Large exposures can result in loss of consciousness, arrhythmias, seizures, or death.

Overview of Acute Carbon Monoxide Toxicity and Modes of Action. Carbon monoxide exerts effects on cell metabolism through both hypoxic and non-hypoxic mechanisms. Both types of effects are thought to be largely (but not entirely) the result of the ability of carbon monoxide to bind to heme and alter function and/or metabolism of heme proteins.

Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. It is produced by the incomplete burning of various fuels, including coal, wood, charcoal, oil, kerosene, propane, and natural gas.

In general, a carboxyhemoglobin (COHb) level of 10-20% will only cause slight headaches [NIOSH 1972] and a COHb of 11-13% will have no effect on hand and foot reaction time, hand steadiness, or coordination [Stewart and Peterson 1970]. At a COHb of 35%, manual dexterity is impaired [Stewart 1975].

May range from "flu-like" symptoms to coma. Can occur days to weeks after apparent resolution of acute symptoms in up to 46% of patients. The globus pallidus is the most commonly affected area.
