X47.3: Accidental poisoning by and exposure to carbon monoxide from other sources

Accidental poisoning by and exposure to carbon monoxide from other sources, not including suicide and intentional self-harm, refers to unintended inhalation of carbon monoxide gas. This type of accidental poisoning often happens due to improper use or malfunctioning of gas appliances, engines, fires, or heating systems. Carbon monoxide is colorless and odorless, making it particularly dangerous as it can be present without any noticeable signs. When inhaled, it interferes with the body's ability to transport oxygen around the body, leading to symptoms such as headaches, dizziness, weakness, vomiting, chest pain, and confusion. In severe cases, it can result in loss of consciousness and is life-threatening. It majorly affects the cardiovascular and nervous system. The disease progression usually depends on the duration and intensity of exposure to the gas. Varying degrees of permanent neurological damage may occur in severe cases.
