Answer

HBO therapy also displaces CO from intracellular stores and may improve mitochondrial function. HBO requires special facilities that are not available at all centers, resulting in a delay in treatment while the patient is transported to facility with HBO.

Hyperbaric therapy should be considered in those patients who have high carboxyhemoglobin levels greater than 25%, who are unconsciousness, have other neurologic findings, or have severe metabolic acidosis (ph < 7.1). The benefit of treating patients 12 hours or more after CO exposure remains unproven.
