What is the condition called when levels of carbon monoxide rise in the blood and tissues?

The condition characterized by elevated levels of carbon monoxide in the blood and tissues is known as carbon monoxide poisoning. This occurs when carbon monoxide binds with hemoglobin in the red blood cells, forming carboxyhemoglobin. This binding is much more effective than that of oxygen, which significantly reduces the blood's oxygen-carrying capacity, leading to hypoxia (a state of reduced oxygen availability) in tissues.

Understanding this condition is crucial, as carbon monoxide is a colorless, odorless gas commonly produced by incomplete combustion of fossil fuels, making it a silent but deadly hazard. It can cause a range of symptoms from mild headache and dizziness to severe neurological damage and death if not promptly recognized and treated. Immediate removal from the source of exposure and supplemental oxygen therapy are important treatment steps to reverse the effects of carbon monoxide poisoning.
