Identification of Tasks Sensitive to Hyperbaria with Determination of Time Interval Effects on Performance

Abstract

Eight Navy hyperbaric chamber technicians performed adaptive tracking and mental arithmetic tasks during four weekly 30-minute exposures; two each at pressure equivalents of 33 and 198 foot depths. Order of exposure was counterbalanced over subjects. Much larger decrements in tracking performance were found in the first 198 foot exposure than in the second. The findings suggest that, until now, the effects of situation-specific experience on 'nitrogen narcosis', as opposed to those of general experience in hyperbaric contexts, have been seriously under-estimated in practice and in studies of the depth-performance relationship.
