What Researchers Did
Researchers measured brain and blood oxygen levels in traumatic brain injury patients before and after hyperbaric oxygen therapy and compared them to healthy people.
What They Found
This study compared regional brain oxygen saturation (rSO2) in 40 sub-acute traumatic brain injury patients given 90 minutes of 100% oxygen hyperbaric therapy to 20 healthy controls, finding no significant change in rSO2 within patients after treatment. However, rSO2 levels in patients, both before and after treatment, were significantly lower than in the healthy control group. Blood oxygen partial pressure (PaO2) also decreased significantly after 30 minutes of hyperbaric oxygen treatment.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study involved a small number of participants (40 patients, 20 controls) and measured oxygen levels at only a few time points, so it could not identify the underlying mechanism behind hyperbaric oxygen's effect on TBI recovery.
