Carbon monoxide poisoning

About Carbon monoxide poisoning

Carbon monoxide poisoning can be a life threatening problem. The disorder occurs when one breathes too much carbon monoxide. Carbon monoxide is a gas produced by burning any type of fuel-gas, oil, kerosene, wood, or charcoal. Faulty house heaters, holes in mufflers, and building fires are common causes of exposure. This poisoning is especially dangerous for pregnant women since the unborn baby is very susceptible to the damaging effects of carbon monoxide. Carbon monoxide prevents a patient's cells from using oxygen normally causing significant cardiac and nervous system problems.
