What Researchers Did
Researchers described three patients who received hyperbaric oxygen therapy for decompression sickness symptoms several days after their diving incidents.
What They Found
All three patients (100%) experienced a complete disappearance of their symptoms despite receiving treatment three to seven days after their original exposure. This suggests that even delayed hyperbaric oxygen treatment can effectively resolve symptoms of decompression sickness, possibly by addressing both gas bubbles and tissue oxygen deprivation. The authors recommend treating symptoms whenever they are seen, even up to 10-14 days post-injury.
What This Means for Canadian Patients
This study suggests that Canadian patients experiencing decompression sickness symptoms, even days after a dive, should still seek hyperbaric oxygen therapy. It indicates that treatment can be effective even when not administered immediately, offering hope for symptom resolution and recovery.
Canadian Relevance
This study covers decompression sickness, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
As a case report, this study is limited by its small sample size of only three patients, meaning the findings may not apply to everyone.
