Testing of Revised Unlimited-Duration Upward Excursions during Helium-Oxygen Saturation Dives

Abstract

As originally published in 1978, the U.S. Navy Unlimited-Duration Saturation Excursion Limits were found to result in an occasional case of vestibular decompression sickness (DCS) after upward excursions from storage depths in the 800-1000 feet of seawater (fsw) range. A series of dives was undertaken to revise these limits. Fifty divers performed a total of 164 man- excursions during 9 saturation dives with maximum storage depths of 36 to 1100 fsw. All excursions tested were upward excursions taken after saturation at the initial storage depth. A total of 130 man-excursions were at or greater than the maximum limits. Keywords: Saturation diving, Decompression, Saturation excursions, Upward excursions, Mathematical modeling, Decompression sickness.
