Abstract : Twenty-five subjects, who failed during an exposure to 35,000 feet for 40 minutes and 40,000 feet for 10 minutes were retested at these same altitudes. Fifteen of the 25 failed again to complete the test, and 10 completed the test without incapacitating symptoms. Following one hour of preoxygenation at sea level and at rest, all 25 were exposed to 35,000 feet for 4 hours. Only 3 were unable to complete the 4 hours without incapacitating symptoms of decompression illness. Following one hour of preoxygenation at rest at sea level, 88 percent of susceptible individuals were protected from incapacitating symptoms of decompression illness at 35,000 feet for 4 hours. Conclusions: Denitrogenation for 60 minutes at rest at sea level protected for at least 4 hours at a pressure altitude of 35,000 feet 88 percent of individuals who were proven susceptible to the effects of low barometric pressure.
