Y17: Poisoning by and exposure to carbon monoxide and other gases and vapours, undetermined intent

Poisoning by and exposure to carbon monoxide and other gases and vapours of undetermined intent, classified under the ICD-10 group range Y17, includes diverse health conditions arising from inadvertent or unestablished motive of contact with harmful gases. Carbon monoxide, a common example, is a lethal, colorless, and odorless gas produced commonly in domestic or industrial settings. Exposure to this gas can result in mild symptoms such as headaches, dizziness, and nausea, or, in severe instances, confusion, unconsciousness or even death. Prolonged exposure can significantly affect the brain and heart leading to long-term disability. Similarly, vapours and other gases such as industrial pollutants or gaseous poisons can induce comparable symptoms and disease progression, predominantly affecting the respiratory system, cardiovascular system, and the central nervous system. The severity of these conditions varies widely, dependent upon the type and concentration of the gas, duration of exposure and individual health factors.
