Hyperbaric oxygen vs Normobaric Oxygen (NBO)

Presence of symptoms or signs at time of primary analysis (4‐6 weeks) · patients with carbon monoxide poisoning

It is very uncertain whether hyperbaric Oxygen (HBO) changes presence of symptoms or signs at time of primary analysis (4‐6 weeks) compared with normobaric Oxygen (NBO) (very low certainty).
