Repetitive Excursion Dives from Saturated Depths on Helium-Oxygen Mixtures. Phase III. Saturation Depth 300 Feet

摘要

Three 300-foot He02 saturation dives were conducted at the Navy Experimental Diving Unit to verify a no-decompression repetitive excursion format developed by the Deep Submergence Systems Project (PM-11). The table for this series of dives is the same as the one previously tested and found to be satisfactory for repetitive-excursion dives from a saturation depth of 350 feet. Twelve divers completed a total of 216 man-excursion dives from the saturation depth to depths not exceeding 150 feet deeper than their base depth. No symptoms of decompression sickness were reported during the excursion dives, during the bottom time at 300 feet or throughout the decompression on returning to the surface. (Author)
