What Researchers Did
Researchers investigated the effects of 60-minute hyperbaric oxygen treatment on peripheral blood flow and transcutaneous oxygen pressure in the forehead, forearm, and foot of 20 healthy volunteers.
What They Found
Peripheral blood flow initially decreased by 7-23% across body parts but then slowly increased, and post-exposure, it rose by 4-76%. Concurrently, transcutaneous oxygen pressure significantly increased in all body parts during HBO exposure, reaching 200-500% of baseline.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation is that the study was conducted on healthy volunteers, not patients with circulatory disorders, which may limit generalizability.
