X67: Intentional self-poisoning by and exposure to carbon monoxide and other gases and vapours

Intentional self-poisoning by and exposure to carbon monoxide and other gases, classified under ICD-10 code X67, refers to a group of conditions often characterized by a person purposefully inhaling or exposing themselves to carbon monoxide or other harmful gases. Carbon monoxide, a dangerous gas produced by burning fuels, is colorless, odorless, and tasteless, making it hard to detect. Inhalation can lead to life-threatening health consequences. Symptoms usually include headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. Over time, prolonged or heavy exposure can result in loss of consciousness, irregular heartbeat, significant brain damage, and even death. The severity of the condition ultimately depends on the concentration of the gas and length of exposure. Most cases result from environmental exposure, such as being in a closed space with a running engine or inhaling smoke from a fire. However, this category is specifically for cases where the exposure is self-inflicted.
