Hyperbaric Oxygen in acute stroke – a critical hyperbaric view

Human studies of hyperbaric oxygen (HBO) in thromboembolic acute stroke have yielded conflicting results. A reason might be the difference in in-clusion criteria. One positive study used HBO within 24 hours, a subsequent negative one within same time period, a preceding within 14 days of symptom onset. Additionally, interventions were different (HBO alone, combined with vitamin E, and combined with low-dose heparin). Besides, surplus pressure, its application time, and intervals of repeated HBO treatment units varied substantially indicating different dosage and dosage intensity. Available human studies used HBO…
