What Researchers Did
The authors reviewed the use of oxygen therapy for treating carbon monoxide poisoning.
What They Found
This is a review article that concludes hyperbaric oxygen (HBO) has been shown to be more effective than normobaric oxygen (NBO) at preventing cognitive after-effects of CO poisoning. It identifies criteria commonly accepted for HBO treatment: a comatose patient, loss of consciousness, neuropsychological and cardiac symptoms, and pregnancy. Patients who do not meet these criteria are treated with a correct NBO regimen instead.
Canadian Relevance

Study Limitations
As a review and set of recommendations rather than original research, this article does not report its own trial data, sample size, or statistical testing to support the comparison between HBO and NBO.
