Y17.2: Poisoning by and exposure to carbon monoxide from other domestic fuels, undetermined intent

Poisoning by and exposure to carbon monoxide from other domestic fuels refers to a serious medical condition that occurs when a person inadvertently inhales carbon monoxide gas. This gas is not visible, odorless, and tasteless, often produced from faulty, improperly used or vented domestic appliances like heaters, engines or fires that burn fossil fuels. Once inhaled, carbon monoxide interferes with the oxygen transport and delivery mechanisms in the body, limiting the oxygen supply to vital organs like the heart and brain. Symptoms can often begin subtly but gradually intensify. Initial symptoms may include headaches, dizziness, weakness, nausea, vomiting, chest pain, and confusion. As exposure continues or increases, these can progress to unconsciousness, arrhythmias, seizures, or even death. This condition is considered a medical emergency requiring immediate attention. It is categorized by an undetermined intent, which indicates that it is unclear whether the exposure was accidental, intentional or otherwise.
