What Researchers Did
This review analyzed data from Medline, ISI Web of Science, and internet search engines to compare decompression sickness risk across four groups of breath-hold divers.
What They Found
The review identified approximately 90 cases of decompression sickness (DCS) following repetitive breath-hold dives. While the number of traditional divers like amas is decreasing, accidents among spear fishers and free-dive athletes are increasing, with world records now reaching depths of 171 meters.
What This Means for Canadian Patients
Canadian patients who engage in breath-hold diving, including spear fishing or competitive free-diving, should be aware of the significant risk of decompression sickness. Recognizing the symptoms and understanding safe diving practices are crucial to prevent serious health complications from repetitive deep dives.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
The review's reliance on reported cases and diverse data sources may not fully capture the true incidence of decompression sickness in breath-hold divers.
