Y17.0: Poisoning by and exposure to carbon monoxide from combustion engine exhaust, undetermined intent

Poisoning by and exposure to carbon monoxide from combustion engine exhaust, undetermined intent, refers to the unintended or unknown intake of carbon monoxide, a potentially deadly gas that is colorless and odorless, which originates from the exhaust of a combustion engine. This hazardous gas can infiltrate the body through the respiratory system, substituting oxygen in red blood cells which results in a shortage of necessary oxygen in tissues and organs. Common symptoms often include headaches, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. Extreme exposure may cause loss of consciousness and can even lead to death. Particularly, this condition specifies that the intent behind the exposure, whether it was accidental or deliberate, is undetermined.
