X47.0: Accidental poisoning by and exposure to carbon monoxide from combustion engine exhaust

Accidental poisoning by and exposure to carbon monoxide from combustion engine exhaust is a potentially life-threatening condition that occurs when an individual inhales carbon monoxide (CO), a toxic gas produced by burning gasoline in an engine. It's invisible, odorless, and non-irritating, which makes it difficult to detect without a device. In the initial stages of poisoning, symptoms are often invisible or confuse with other illnesses like flu, as they include headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. As more CO is inhaled, the body replaces the oxygen in the red blood cells with carbon monoxide, impairing the ability to transport oxygen, which can lead to severe tissue damage. If the exposure is large or prolonged, it can result in unconsciousness, brain damage or death.
