Abstract
DCIEM has developed a new mathematical model for decompressing compressed air divers. The model, referred to as the DCIEM 1983 DECOMPRESSION MODEL, has been employed for real-time computer-controlled diving using the DCIEM XDC-2 decompression computer. The report presents the results of 391 experimental man-dives within the proposed Canadian Forces "normal" air diving limits decompressed on the new model with Standard Air, In-Water Oxygen, and Surface Oxygen decompression procedures. Both single dives and repetition dives were examined. The effectiveness of the decompression was assessed both subjectively (classical symptoms of decompression sickness) and by Doppler ultrasonic bubble detection methods. The decompression schedules based on the DCIEM 1983 model are considerably more conservative than the equivalent United States Navy (USN) and Royal Navy (RN) schedules. TRUNCATED
