Abstract
Conclusions
1. The preflight administration of a single dose of glucose in water to individuals on a normal diet produced a significant increase in the resistance to unconsciousness from anoxia at 27,000 and 30,000 ft. 2. The protection afforded flying personnel by the glucose solution was greater 30 to 50 minutes following its administration than after an interval of 60 to 80 minutes. 3. At 27,000 ft. the mean duration of consciousness was increased by approximately 40%, or more than one minute, by the preflight ingestion of glucose solution. 4. Vitamin C, either alone or in conjunction with glucose, had no demonstrable effect on the duration of consciousness.
