What Researchers Did
Researchers investigated how hyperbaric air and oxygen influenced breath-holding time in 36 healthy volunteers.
What They Found
Breath-holding time (BHT) significantly increased in hyperbaric air (from 108 to 230 seconds) compared to hyperbaric oxygen (from 137 to 180 seconds). The prolongation of BHT was significantly greater in the hyperbaric air group, where transcutaneous carbon dioxide tension was also higher (59 mm Hg vs. 54 mm Hg) at the end of breath-holding.
Canadian Relevance
This study has no direct Canadian connection or specific relevance to Canadian healthcare policies or patient populations.
Study Limitations
The study was conducted on a small group of healthy volunteers, which may limit the generalizability of these findings to broader populations or clinical settings.
