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.
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 ...
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 RDP was developed by DSAT and was the first dive table developed exclusively for no-stop recreational diving. [2] There are four types of RDPs: the original table version first introduced in 1988 along with a circular slide rule version called The Wheel, followed by the eRDP, an electronic version introduced in 2005 and the eRDPML, an ...
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]
VVAL 18 is a deterministic model that utilizes the Naval Medical Research Institute Linear Exponential (NMRI LE1 PDA) data set for calculation of decompression schedules. . Phase two testing of the US Navy Diving Computer produced an acceptable algorithm with an expected maximum incidence of decompression sickness (DCS) less than 3.5% assuming that occurrence followed the binomial distribution ...
Hennessy formulated that it was possible to convert standard air decompression tables for no-stop diving at altitude or from a habitat based on phase equilibration theory. [14] Albert A. Bühlmann recognized the problem [15] [16] [17] and proposed a method which calculated maximum nitrogen loading in the tissues at a particular ambient pressure ...
