Repetitive Diving Decompression Tables

Book excerpt: A decompression procedure for repetitive diving to depths of 190 feet was devised employing modified Haldane principles which have been reported previously. The repetitive diving tables provide a system by which a diver can determine the necessary increase in decompression time on the second and successive dives, based on the amount of excess inert gas tension in his body after completion of the previous dive. The amount by which the decompression time must be increased varies inversely with the time (on surface) interval between dives. The information for using this system is obtained from four tables i.e. Decompression Table, No Decompression Table, Surface Interval Table and the Repetitive Dive Table. The validity of this procedure was tested by performing 62 repetitive dives with random combinations of depth, time and surface interval.
