Signs of Carbon Monoxide Poisoning

Extra Mile Staff

Carbon monoxide is a highly toxic gas produced when organic matter is burned in an environment without sufficient oxygen. When inhaled, it enters the bloodstream and prevents red blood cells from carrying oxygen. Without oxygen, the cells die. Even non-lethal levels can cause grievous harm to the central nervous system and the heart.

Because carbon monoxide is colorless, odorless and tasteless, it may be hard to detect. But there are warning symptoms that are indicative of carbon monoxide poisoning. Knowing what they are could save your life.
