SCHEDULE OF ASCENT TO THE SURFACE AFTER SATURATION DIVE ON HELIOX MIXTURE TO 500 METERS

Abstract

Modified US navy Tables of decompression and stop times were used to provide theoretical grounds for reckoning of ascent rate to the surface after saturation dives to 500 on a heliox mixture lasting 18 days, 12 hrs and 35 minutes. According to calculation, dynamics of helium tension in the slowest body tissues points to oversaturation, the risk of gas bubble formation and development of decompression sickness symptoms. This risk can be averted fully by decelerating the standard ascent rate in half.
