What Researchers Did
Researchers analyzed 571 cases of hyperbaric oxygen-treated decompression illness in Finland between 1999 and 2018, comparing technical and non-technical divers.
What They Found
The study found a mean of 29 DCI cases treated annually, with 200 technical divers and 371 non-technical divers among the 571 patients. Technical dives were typically deeper, longer, and performed in cold or overhead environments, and technical divers were more likely to use first aid oxygen. Despite a shift towards more demanding technical diving, the number of DCI cases remained surprisingly constant over the 20-year period.
What This Means for Canadian Patients
Canadian divers, particularly those engaging in technical diving, should recognize the increased demands and potential risks associated with deeper, longer, and colder dives. Emphasizing proper training and the immediate use of first aid oxygen can improve outcomes for all divers experiencing decompression illness.
Canadian Relevance
This study focuses on decompression illness in Finland and has no direct Canadian connection.
Study Limitations
As an observational study, it cannot establish causality and its findings may not be fully generalizable to diving populations outside of Finland.
