What Researchers Did
Researchers reviewed past medical records to see how well different hyperbaric oxygen therapy protocols worked for recreational divers with decompression sickness.
What They Found
Out of 103 recreational divers treated for decompression sickness, 53 patients (51.5%) experienced complete relief of symptoms, while 45 patients (43.7%) had partial relief, and 5 patients (4.8%) reported no relief. Among those who achieved complete relief, 28 patients (53%) needed only one hyperbaric recompression treatment. The depth of the diver's first dive and how symptoms changed within the first 20 minutes of the first treatment were linked to the overall treatment outcome.
What This Means for Canadian Patients
This study provides valuable insights into the effectiveness of hyperbaric oxygen therapy (HBOT) for treating decompression sickness, a condition recognized by Health Canada. Canadian recreational divers experiencing DCS can expect a high likelihood of complete or partial symptom relief with recompression treatments, often within a few sessions. The findings suggest that early symptom changes during treatment could help predict recovery.
Canadian Relevance
This study covers decompression sickness, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
This study was a single-center retrospective review, meaning it looked back at past records from one location, which might limit how broadly its findings apply to all divers.
