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.

The entry requirements for diver training depend on the specific training involved, but generally include medical fitness to dive. Fitness to dive, (also medical fitness to dive), is the medical and physical suitability of a diver to function safely in the underwater environment using underwater diving equipment and procedures.
The rate of decompression typically ranges between 3 and 6 fsw (0.9 and 1.8 msw) per hour. The US Navy Heliox saturation decompression rates require a partial pressure of oxygen to be maintained at between 0.44 and 0.48 atm when possible, but not to exceed 23% by volume, to restrict the risk of fire.

[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 ...
In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives.
