<unk>  occurs after the inhalation of<unk><unk>  gas.<unk><unk>  (CO) is a product of combustion of organic matter under conditions of restricted oxygen supply, which prevents complete oxidation to<unk>  dioxide (CO2).<unk><unk>  is colorless, odorless, tasteless, and non-irritating, making it difficult to detect.<unk><unk>  is a significantly toxic gas with poisoning being the most common type of fatal poisoning in many countries. Symptoms of mild poisoning include headaches and flu-like effects; larger exposures can lead to significant toxicity of the central nervous system and heart. Following poisoning, long-term sequelae often occur.<unk><unk>  can also have severe effects on the fetus of a pregnant woman. The mechanisms by which<unk><unk>  produces toxic effects are not yet fully understood, but hemoglobin, myoglobin, and mitochondrial cytochrome oxidase are thought to be compromised. Treatment largely consists of administering 100% oxygen or hyperbaric oxygen therapy, although the optimum treatment remains controversial. Domestic<unk>  can be prevented by the use of household<unk><unk>  detectors.
