Which therapy is used specifically as a treatment for CO poisoning or smoke inhalation?

Carbon monoxide poisoning creates tissue hypoxia because CO binds tightly to hemoglobin, reducing oxygen delivery to tissues. Hyperbaric oxygen therapy delivers 100% oxygen at high pressure, which dramatically increases the amount of oxygen dissolved in plasma and speeds the release of CO from hemoglobin and myoglobin. This combination quickly improves tissue oxygenation and shortens the carboxyhemoglobin half-life, helping to prevent ongoing hypoxic injury and reduce the risk of delayed neurological problems. For this reason, hyperbaric oxygen therapy is the therapy specifically used for CO poisoning and smoke inhalation, especially in more severe cases or when neurologic symptoms, pregnancy, or very high CO levels are present. Other options like initial airway assessment or bronchoscopy address airway issues rather than treating the CO-related problem, and while breathing 100% oxygen at normal pressure helps, it doesn’t offer the same rapid CO clearance and neuroprotection as HBO.
