What Researchers Did
Researchers treated patients with various stages of peripheral vascular disease using hyperbaric oxygen therapy (HBT), which involves inhaling 100% oxygen under pressure.
What They Found
Clinical symptoms improved in 70% of patients, and the ankle/brachial index increased by more than 0.10 in 47%. Photoplethysmographic pulse appearance was detected in roughly one third of patients, and plasma malondialdehyde levels decreased after HBT.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation is that the observed lack of potentially harmful side effects was only confirmed for the short term.
