What Researchers Did
Researchers conducted an international online survey among 558 certified trimix divers to document their diving practices, experience, and self-reported unusual symptoms and incidents.
What They Found
Forty-two percent of divers reported one or more medical risk factors, and 79% used rebreathers at least occasionally. Thirty-six percent (199/558) reported experiencing diving-related incident symptoms, with 61% (121/199) expressing certainty, and 10% experienced symptoms suggestive of gas toxicity. Gas density at depth frequently exceeded current recommendations.
What This Means for Canadian Patients
Canadian technical divers should be aware of the high prevalence of medical risk factors and the potential for diving-related incidents, including gas toxicity and decompression sickness. This underscores the need for meticulous dive planning, strict adherence to safety guidelines, and timely reporting of any unusual symptoms to medical professionals.
Canadian Relevance
The study's international scope and the explicit Canadian relevance noted in the metadata indicate its findings are directly applicable to the Canadian technical diving community.
Study Limitations
The study relied on self-reported data from an online survey, which may introduce recall bias and limit the generalizability of the findings.
