X47.4: Accidental poisoning by and exposure to carbon monoxide from unspecified sources

Accidental poisoning by and exposure to carbon monoxide from unspecified sources, is a potentially dangerous condition that occurs when an individual inhales carbon monoxide (CO), a harmful gas that is colorless, odorless, and tasteless. This poisonous gas is usually found in combustion fumes, including those produced by gas ranges, heaters, fireplaces, car exhausts, and certain types of indoor fires. When inhaled into the body, carbon monoxide displaces the oxygen in our red blood cells, blocking oxygen from reaching our tissues and organs. Common symptoms can range from headache, dizziness, weakness, vomiting, chest pain to confusion. This condition can progress rapidly from mild symptoms to severe life-threatening complications such as loss of consciousness or death, particularly if the individual is exposed to high levels of carbon monoxide or for a prolonged duration. The cardiovascular, respiratory and nervous systems are commonly the most affected.
