ISO 13293 provides minimum training standards for gas blenders for recreational diving services at two levels. Level 1 gas blender is competent to blend nitrox and handle oxygen, air and nitrox, i.e. nitrox gas blender, and a level 2 gas blender is also competent to mix gases containing helium and argon, i.e, a trimix gas blender.

Nitrox is known by many names: Enriched Air Nitrox, Oxygen Enriched Air, Nitrox, EANx or Safe Air. [ 3 ] [ 23 ] Since the word is a compound contraction or coined word and not an acronym, it should not be written in all upper case characters as "NITROX", [ 3 ] but may be initially capitalized when referring to specific mixtures such as Nitrox32 ...
The equivalent air depth, for a given nitrox mix and depth, is the depth of a dive when breathing air that would have the same partial pressure of nitrogen. So, for example, a gas mix containing 36% oxygen (EAN36) being used at 27 metres (89 ft) has an EAD of 20 metres (66 ft).
Two U.S. Marines of the Maritime Special Purpose Force operating a Diver Propulsion Device (DPD). A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle, sea scooter, [1] underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater.
In underwater diving activities such as saturation diving, technical diving and nitrox diving, the maximum operating depth (MOD) of a breathing gas is the depth below which the partial pressure of oxygen (pO 2) of the gas mix exceeds an acceptable limit.

The Advanced SEAL Delivery System (ASDS) was a midget submarine operated by the United States Navy and United States Special Operations Command.It provided stealthy submerged transportation for United States Navy SEALs from the decks of nuclear submarines for use as an insertion platform for covert and clandestine special operations missions.
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.
