The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of J.S.Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model.
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 ...
What is commonly known as no-decompression diving, or more accurately no-stop decompression, relies on limiting ascent rate for avoidance of excessive bubble formation. [16] The procedures used for decompression depend on the mode of diving, the available equipment, the site and environment and the actual dive profile.
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, [11] and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during ...
Partial pressure of oxygen is usually limited to 1.6 bar during in-water decompression for scuba divers, but can be up to 1.9 bar in-water and 2.2 bar in the chamber when using the US Navy tables for surface decompression, [9] and up to 2.8 bar for therapeutic decompression.
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.
Divers Alert Network (DAN) is a group of not-for-profit organisations dedicated to improving diving safety for all divers. It was founded in Durham, North Carolina, in 1980 at Duke University to provide 24/7 telephone diving medical assistance.
Wienke proposed guidelines for decompression diving at altitude in 1993. [20] Egi and Brubakk reviewed various models for preparing tables for diving at altitude. [21] [22] Paulev and Zubieta have created a new conversion factor in order to make any sea-level dive table usable during high altitude diving in 2007. [23] [22]
