What Researchers Did
Researchers conducted a review to summarize the literature on hyperbaric oxygen therapy's effects on brain oxygenation, cerebral blood flow, and intracranial pressure in healthy and injured brains.
What They Found
The review found that hyperbaric oxygen therapy significantly increases blood oxygen content and is advocated for treating at least four conditions, including air embolism and carbon monoxide poisoning. While HBO affects brain oxygenation, cerebral blood flow, and intracranial pressure, the definitive mechanisms by which these three factors impart protection are still being established.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A key limitation highlighted by the review is the ongoing uncertainty and lack of definitive established mechanisms of action for hyperbaric oxygen therapy.
