What is the definitive treatment for carbon monoxide poisoning?

Hyperbaric oxygen therapy is considered the definitive treatment for carbon monoxide poisoning because it effectively reduces the half-life of carboxyhemoglobin, the form of hemoglobin that is bound to carbon monoxide. By increasing the pressure and providing 100% oxygen, this therapy enhances oxygen delivery to the tissues and promotes the elimination of carbon monoxide from the bloodstream more rapidly than standard oxygen therapy alone.

Carbon monoxide has a strong affinity for hemoglobin, and while standard oxygen therapy can help in displacing some of the carbon monoxide, it is often insufficient in treating more severe cases of poisoning. Hyperbaric oxygen therapy can significantly reduce the risk of long-term complications associated with carbon monoxide exposure, such as neurological damage, by ensuring that the brain and vital organs receive adequate oxygen while also facilitating the rapid removal of carbon monoxide from the body.

Other options like intravenous fluids and antidotes are not appropriate or effective treatments for carbon monoxide poisoning.
