<Tr> <Td_colspan="2"> (edit on Wikidata) </Td> </Tr> <P> Carbon monoxide poisoning typically occurs from breathing in too much carbon monoxide (CO). Symptoms are often described as "flu - like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion . Large exposures can result in loss of consciousness, arrhythmias, seizures, or death . The classically described "cherry red skin" rarely occurs . Long term complications may include feeling tired, trouble with memory, and movement problems . In those exposed to smoke, cyanide toxicity should also be considered . </P> <P> Carbon monoxide poisoning can occur accidentally or as an attempt to end one's life . CO is a colorless and odorless gas which is initially non-irritating . It is produced during incomplete burning of organic matter . This can occur from motor vehicles, heaters, or cooking equipment that run on carbon - based fuels . It can also occur from exposure to methylene chloride . Carbon monoxide primarily causes adverse effects by combining with hemoglobin to form carboxyhemoglobin (HbCO) preventing the blood from carrying oxygen . Additionally, myoglobin and mitochondrial cytochrome oxidase are affected . Diagnosis is based on a HbCO level of more than 3% among nonsmokers and more than 10% among smokers . </P> <P> Efforts to prevent poisoning include carbon monoxide detectors, proper venting of gas appliances, keeping chimneys clean, and keeping exhaust systems of vehicles in good repair . Treatment of poisoning generally consists of giving 100% oxygen along with supportive care . This should generally be carried out until symptoms are no longer present and the HbCO level is less than 10% . While hyperbaric oxygen therapy is used for severe poisonings, the benefit over standard oxygen delivery is unclear . The risk of death among those affected is between 1 and 30% . </P>
