Title and Subtitle: Effects of decompression on operator performance.

Report Date: April 1966

Authors: O'Connor WF, Pendergrass GE.

Abstract: The study was performed to provide more quantitative estimates of degradation of pilot performance following decompression and the extent to which a decompression with mask donning interrupts the task of piloting. The experiments utilized a Scow complex coordinator and were conducted in an altitude chamber. Subjects were decompressed to altitudes from 25,000 to 41,000 feet. Results indicate impairment of performance for 2 to 4 minutes following rapid decompression. Total time loss from mask donning is much more extended than the 5 to 6 seconds required to don the mask.

Key Words: decompression, aviation medicine, performance (human), pilots, oxygen masks, high altitude, stress (physiology).
