What Researchers Did
Researchers tested whether the high-pressure environment inside a hyperbaric chamber could kill or reduce two common bacteria (Staph aureus and E. coli) deposited on plastic, metal, and seat upholstery surfaces.
What They Found
Pressurized air at 253 kPa for 95 minutes had no significant effect on bacterial survival compared to bacteria left outside the chamber under normal air pressure. This was true for all three surface types and both bacterial species tested (p > 0.05 for all comparisons).
What This Means for Canadian Patients
Hyperbaric chambers require the same rigorous cleaning and infection control protocols as any other medical setting, the pressure environment itself does not reduce bacterial contamination. Canadian hyperbaric facilities must maintain standard infection control procedures and cannot rely on hyperbaric conditions as a substitute for surface cleaning.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study used an experimental chamber rather than a clinical monoplace or multiplace chamber, and tested only two bacterial strains, so results may not reflect all pathogens encountered in real treatment settings.
