What Researchers Did
Researchers conducted an epidemiologic review of hyperbaric and hypobaric chamber fires from 1923 to 1996, analyzing data from literature and a specialized database.
What They Found
From 1923 to 1996, there were 77 human fatalities in 35 hyperbaric chamber fires and 2 fatalities in 3 hypobaric chamber fires, with no fatalities reported in North American clinical hyperbaric chambers. Electrical ignition caused fires before 1980, while prohibited occupant-carried items were the primary cause since 1980, with all fatal fires occurring in oxygen-enriched atmospheres (>28% oxygen).
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric or hypobaric therapy should be reassured by strict safety protocols designed to prevent fires, especially concerning prohibited items and oxygen levels. Adherence to facility guidelines, including leaving all personal items outside the chamber, is crucial for patient safety during treatment.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
A limitation of this review is its reliance on historical data from 1923 to 1996, which may not fully reflect current safety practices or incident reporting.
