Plain English Summary
This blinded trial found fewer cognitive complications after acute carbon monoxide poisoning in the HBOT group than in the comparison group.
Limitations & context: The trial stopped early for benefit. Other trials have not consistently reproduced the findings; read alongside the systematic review.

Plain English Summary
In this randomized trial of mild to moderate carbon monoxide poisoning, no delayed neurological complications developed in 30 patients treated with HBOT, compared with 7 of 30 patients (23%) given 100% oxygen at normal pressure. The authors concluded that early HBOT reduced these complications in the patients studied.
Limitations & context: Small trial with 30 patients per group. Participants presented within 6 hours and had no history of loss of consciousness or cardiac instability, so the results do not establish effectiveness in all poisoning cases. Other trials have reported conflicting results; this positive study alone does not settle the overall evidence. Carbon monoxide poisoning requires emergency medical assessment and treatment.
