New No-Decompression Tables Based On No-Decompression Limits Determined By Doppler Ultrasonic Bubble Detection

Studies done by Spencer in 1976 produced new no-decompression limits designed to eliminate venous bubbles. This paper has used those limits as the basis for a full set of no-decompression tables. The resulting tables are more conservative than the Navy tables but have more potential for multi-level diving. Recently there has been growing concern in the diving community that the Navy no-decompression tables may not be as safe for the sport diver (scuba) as they should be. Studies have shown that there is bubble formation in divers who have been exposed to dives within the Navy's limits (Spencer 1976). Using these findings new no-decompression limits were calculated to prevent the formation of bubbles. This paper carries this development one step further by developing a set of no-decompression tables based on these new limits. Grant no. NA79AA-D-00093
