dc.description.abstract Methods for programming a wrist worn Underwater Decompression Computer (UDC) were investigated and tested. All testing was done on the MK-15 UBA which supplies a constant P sub O2 of 0.7 ATA in N2. Testing was done submerged in water temperatures of 73 - 78 F and with dive subjects performing moderate exercise. A total of 445 man-dives were conducted to depths of 175 FSW, and a total of 22 cases of decompression sickness occurred. A total of 5 methods for computing decompression profiles were investigated and of these one was selected as being the most suitable for programming the UDC. The method chosen would not decompress divers safely from all profiles so its use was restricted to a maximum time of 30 min at 150 FSW. This restriction was integrated into the program so the UDC could warn the diver if he were exceeding permissible limits at any depth. A total of 178 man-dives were done within the restriction placed on the UDC with only 2 cases of decompression sickness observed. A series of non-repetitive diving tables using the selected method was also produced to permit safely diving the MK 15 UBA without a UDC. (Author) en
