What Researchers Did
Researchers investigated how hyperbaric oxygen therapy affected blood flow in the brains of 23 patients with brain blood vessel problems caused by long-term radiation sickness.
What They Found
All 23 patients showed clinical improvement after receiving hyperbaric oxygen therapy. However, the improvements in brain blood flow did not always directly match the improvements in neurological symptoms.
Canadian Relevance
This study covers delayed radiation injury, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
This small study from 1983 lacked a control group and did not provide specific details on the hyperbaric oxygen therapy protocol or long-term outcomes.
