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.
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 ...
Normal diving decompression procedures range from continuous ascent for no-stop dives, where the necessary decompression occurs during the ascent, which is kept to a controlled rate for this purpose, [16] through staged decompression in open water or in a bell, [17] [18] or following the decompression ceiling, to decompression from saturation ...
These tables used a partial pressure of oxygen of 0.35 to 0.4 bar during decompression, with quite slow decompression rates, which varied with the depth, getting slower as the depth decreased, with a 6-hour stop from midnight and a two-hour stop from 14:00 and a gas fraction limit of 22% for the last part of the ascent to reduce fire risk.
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.
BSAC nitrox decompression tables The PADI Nitrox tables are laid out in what has become a common format for no-stop recreational tables. Dive tables or decompression tables are tabulated data, often in the form of printed cards or booklets, that allow divers to determine a decompression schedule for a given dive profile and breathing gas.

The algorithm is now incorporated into many dive computers and advanced dive planning software. Today it enhances the safety of serious deep and technical divers. [63] NAUI's RGBM decompression tables were developed in 1997 exclusively for NAUI by Dr. Bruce Wienke and Tim O'Leary. [64]
