What treatment is indicated for severe carbon monoxide poisoning?

Hyperbaric oxygen therapy is indicated for severe carbon monoxide poisoning because it significantly enhances the removal of carbon monoxide from the hemoglobin, as well as providing a higher concentration of oxygen that may help prevent further cellular injury and promote healing. During hyperbaric oxygen therapy, the patient is placed in a chamber where the pressure is increased, allowing for greater diffusion of oxygen into tissues that may be hypoxic due to carbon monoxide exposure.

In cases of severe poisoning, especially if symptoms like neurological deficits, confusion, or decreased consciousness are present, hyperbaric oxygen treatment is crucial. It not only helps abolish carbon monoxide from the hemoglobin but also addresses the potential for delayed neurological sequelae by providing oxygen under pressure.

Other treatments such as intubation and ventilation may be necessary depending on the patient’s respiratory status, but they do not remove carbon monoxide or address the underlying toxicological emergency as effectively as hyperbaric oxygen therapy. Antioxidants and fluid resuscitation may be supportive measures but do not directly mitigate the acute effects of carbon monoxide toxicity. Hence, hyperbaric oxygen therapy remains the standard of care in severe cases, highlighting its importance in the management of this life-threatening condition.
