What Researchers Did
Researchers evaluated the effect of long-term intermittent exposure to hyperbaric oxygen on pulmonary function in 65 divers compared to 67 control subjects.
What They Found
The study measured pulmonary ventilation and diffusion capacities in 65 divers and 67 control subjects. Despite the divers' long-term occupational exposure to hyperbaric oxygen, no significant differences (P < 0.05) were found in any measured respiratory parameters between the two groups.
What This Means for Canadian Patients
This study suggests that long-term intermittent hyperbaric oxygen exposure may not significantly impair lung function. Canadian patients undergoing similar exposures, such as professional divers, might find reassurance in these findings regarding their pulmonary health.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian participants.
Study Limitations
The study's findings are limited to a specific population of male divers and may not be generalizable to other groups or different exposure protocols.
