X40-X49: Accidental poisoning by and exposure to noxious substances
X47: Accidental poisoning by and exposure to carbon monoxide and other gases and vapours
Accidental poisoning by and exposure to carbon monoxide and other gases and vapours refers to a group of conditions caused by unintentional contact with, or inhalation of, harmful gases. These can include carbon monoxide, a colorless, odorless gas commonly produced by vehicles and gas appliances, and other harmful vapors found in various environments. When these gases are inhaled, they can interfere with the body's ability to absorb and transport oxygen, leading to a variety of symptoms. Common symptoms include headaches, dizziness, weakness, nausea, vomiting, and shortness of breath. In severe cases, exposure can lead to loss of consciousness, damage to the brain and other organs, and even death. These conditions can progress rapidly, particularly in confined spaces with limited ventilation. The respiratory and circulatory systems are especially affected by these conditions.
