A decompression algorithm is used to calculate the decompression stops needed for a particular dive profile to reduce the risk of decompression sickness occurring after surfacing at the end of a dive. The algorithm can be used to generate decompression schedules for a particular dive profile, decompression tables for more general use, or be ...
NAUI's RGBM decompression tables were developed in 1997 exclusively for NAUI by Dr. Bruce Wienke and Tim O'Leary. [64] NAUI began publishing the only decompression manual with a full set of RGBM tables in 2000 for air, nitrox and trimix for both open and closed-circuit diving. Recreational RGBM no-calculation tables were published in 2001 ...
A "no-stop dive", also commonly but inaccurately referred to as a "no-decompression" dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, [14] and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during ...
The decompression tables or software used to plan the dive, [22] The equipment used to control and monitor depth and dive time, such as: personal dive computers, depth gauges, and timers, [23] Shot lines, surface marker buoys (SMBs), Decompression buoys (DSMBs) and decompression trapezes [23] diving stages (baskets), wet and dry bells,
Basic decompression theory and use of decompression tables is part of the theory component of training for commercial divers, [130] and dive planning based on decompression tables, and the practice and field management of decompression is a significant part of the work of the diving supervisor.
Scuba diving education levels as used by ISO, PADI, CMAS, SSI and NAUI Basic diving skills training in a swimming pool. Recreational diver training is the process of developing knowledge and understanding of the basic principles, and the skills and procedures for the use of scuba equipment so that the diver is able to dive for recreational purposes with acceptable risk using the type of ...
The first NAUI tables were based on reformatted but otherwise unmodified US Navy 1956 tables and issued in the early 1980s. [67] [70] The next version was a NAUI modification of the US Navy 1956 tables using the following modifications, [40] and released a few years later. No decompression limits have been reduced.
Decompression calculations using dive tables for multi-level dives were moderately common practice for advanced recreational diving before dive computers were widely used. [3] Where the dive site and underwater topography permit, divers often prefer to descend initially to maximum depth and slowly ascend throughout the dive. A slow ascent, and ...
