- Abstract
- The effectiveness of pre-breathing 100% oxygen in reducing the incidence of decompression sickness for current Canadian Forces altitude training profiles was studied. Four altitude chamber flights were made. The exposures differed primarily in whether or not oxygen pre-breathing was used, or in the length of time spent at altitude. Twelve subjects were exposed to two training profiles each. The subjects were monitored for intravascular bubbles using a Doppler ultrasonic bubble detector, and any symptoms of decompression sickness were recorded. The practice of breathing oxygen for thirty minutes prior to the exposure appeared to be effective in inhibiting the formation of intravascular bubbles and in reducing the incidence of decompression sickness, provided the time at altitude did not exceed 20 minutes.
