OBSERVATIONS ON EFFICIENCY OF SUBMARINE PERSONNEL DURING PROLONGED SUBMERGENCE WHEN THE ATMOSPHERIC OXYGEN IS MAINTAINED AT 17% AND THE CARBON DIOXIDE AT 3%.

Abstract

The purpose of this investigation was to determine whether the operating efficiency of submarine personnel deteriorated during submergence when the atmospheric oxygen was maintained at 17% and the carbon dioxide at 3% for extended periods. The results of the observations show: (a) Very definitely decreased capacity for physical work for all hands. (b) Very definite decrease in efficiency of night vision for about one third of the ship's company. (c) Indications of marked decrement in mental efficiency for all hands. (d) Very probable decrease in efficiency of interior voice communications. (e) Noticeable, but unproven, tendency towards general decrease in efficiency of radar watch and watch on the bow and stern planes. (f) No indication of deterioration in straightforward listening performance for sonar signals. (g) No reliable evidence either on efficiency in watching the 'Christmas Tree' or memory for numbers.
