X67.4: Intentional self-poisoning by and exposure to carbon monoxide from unspecified sources

Intentional self-poisoning by and exposure to carbon monoxide from unspecified sources refers to the deliberate act of inhaling carbon monoxide gas, which typically results from burning materials or fuels in confined spaces. Carbon monoxide is a colorless, odorless gas, and exposure to it can be lethal. It substitutes the oxygen in the bloodstream, interfering with the ability of blood to carry oxygen to organs and tissues. Common initial symptoms of this condition include headache, mild confusion, tiredness, and nausea. As the exposure increases, these symptoms can progress to dizziness, chest pain, impaired vision and coordination, and in severe cases, loss of consciousness or death. Brain damage may occur due to prolonged deprivation of oxygen. This condition is characterized as an acute event, and widespread body systems may be affected including, but not limited to, the cardiovascular and central nervous systems.
