Results of Psychologic Studies Conducted During Chamber Saturation Dives from 200 Feet to 825 Feet
Abstract
From February 1967 to May 1968, a series of saturation dives was conducted at the U.S. Navy Experimental Diving Unit. These dives were designed to train and select aquanauts for the open sea SEALAB III experiments as well as to measure the psychophysiological effects on man's ability to work at great depths. A wide variety of hematological, biochemical, cardiopulmonary and psychometric studies were made to determine whether changes occurred during exposures to helium-oxygen atmospheres at great depths. The data in this preliminary report was obtained during 14 saturation dives, ranging in depth from 200 feet to 825 feet. Psychological studies were conducted during 'wet' excursion dives to depths of 300, 825 and 1025 feet. Over 25,000 biomedical observations and measurements were obtained in the course of these dives. In general the results indicate that man can effectively, safely work at depths up to 825 feet saturated. Some decrement in cognitive and neuromuscular ability was found as well as in certain pulmonary ventilatory parameters.
