Pryidostigmine and Warm Water Diving Protocol 90-05: 3. Cognitive Performance Assessment

Abstract

This report describes the effects observed in cognitive performance during a study concerned with the consequences of pyridostigmine pretreatment on performance of divers during extended heat and warm water exposures. Ten U.S. Navy divers performed during two 7-hour heat and warm water tests. Each test consisted of a 4-hour predive exposure to 37.8 C air at the surface , followed by a 3-hour dive in 34.4 C water at a depth of 1.6 ATA breathing either air or 100% oxygen. Cognitive tests that measure short-term memory (Matching-to-Sample) and learning capability (Repeated Acquisition) were administered 30 min before entering the heat, after 2 and 4 h in the predive component, and immediately following the dive phase. Vision and coordination tests were conducted during the first and third hours of the predive phase and in rest periods during the dive component.
