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).
