Effect of hyperbaric oxygen therapy on early features of carbon monoxide poisoning focusing on neurological symptoms

In general, patients who are not alert at the time of presentation receive more intensive HBO therapy. According to our study, most intoxication symptoms improve during the early phase of HBO therapy, and delayed neuropsychiatric sequalae can occur in the future, even in initially alert patients. Therefore, physicians should be more careful with patients with neurological symptoms, evidence of myocardial damage, or severely elevated creatine phosphokinase levels, and these patients should be fully administered HBO therapy.
