Hypoxia Induced by Rapid Decompression from 8,000 ft. to 40,000 ft - The Influence of Rate of Decompression
Abstract
Studies were made of the effects upon alveolar gases and electroencephalograms of rapid decompression from 8,000 feet at 1.6 and 12 sec with oxygen delivery 5 min before, immediately at, and 8 sec after the beginning of the decompression. The findings showed that hypoxia induced by delayed oxygen delivery was less on the slower decompression, although it was always severe, even when oxygen was delivered at the beginning of the decompression. A linear relationship was demonstrated between the intensity of the hypoxia, deduced from the changes of alveolar PO2 and the increased activity (variance index) of the 8 - 16 Hz band of the frontal EEG.
