Cognitive and Psychomotor Performance During NOAA OPS 1 and 2
Abstract
The NOAA OPS project developed excursion procedures for shallow nitrogen habitats. Operational verification of the concept was carried out in two laboratory saturation dives using three subjects each. Cognitive and psychomotor performance was evaluated on the subjects under several conditions: at sea level; during normoxic nitrogen saturation exposures of seven-day duration each at pressures equivalent to 30, 60, 90 and 120 feet of sea water (fsw); on compressed air excursions from saturation to depths as great as 300 fsw; and on equivalent air dives as made from the surface in the unsaturated condition. Results indicated that divers can live and work in normoxic nitrogen habitats--to depths as great as 120 fsw for at least one week duration--at performance levels comparable to see level efficiency.
