Abstract
It has generally been supposed that the bends and the chokes1 occur infrequently or not at all at altitudes under 30,000 feet. According to Armstrong,2 "With ascents at rates as high as 12,000 feet per minute up to 30,000 feet, symptoms are seldom noted even after prolonged stays at that altitude." The present report is concerned with demonstrating that this need not be the case and that under appropriate conditions bends equaling in incidence and severity those reported at altitudes above 30,000 feet may be produced in the low pressure chamber at altitudes as low as 26,000 feet. SUBJECTS Subjects participating in these experiments were all volunteers from this unit. It is believed that they represent a fair cross section of Air Corps enlisted personnel. All had passed the required modified "64 examination." Only one of these men was on limited service, and this because of defective vision.This publication has 0 references indexed in Scilit:
