The most commonly used mixture is nitrox, also referred to as Enriched Air Nitrox (EAN), which is air with extra oxygen, often with 32% or 36% oxygen, and thus less nitrogen, reducing the risk of decompression sickness or allowing longer exposure to the same pressure for equal risk. The reduced nitrogen may also allow for no stops or shorter ...
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 ...
Many 16-bit Windows legacy programs can run without changes on newer 32-bit editions of Windows. The reason designers made this possible was to allow software developers time to remedy their software during the industry transition from Windows 3.1 to Windows 95 and later, without restricting the ability for the operating system to be upgraded to a current version before all programs used by a ...
Nitrox is generally understood as air enriched by additional oxygen, as that is the usual method for producing it. Gas fraction of oxygen may range from 22% to 99%, but is more usually in the range of 25% to 40% for bottom gas (breathed during the main part of the dive), and 32 to 80% for decompression mixtures.
As the first agency to offer recreational certification in nitrox, IANTD grew at a steady pace from 1985 through February 1992 with the support of Hyperbarics International. The European Association of Technical Divers (EATD) was formed by Kevin Gurr, Richard Bull, and Rob Palmer in the UK in 1992 and merged into IANTD the following year.

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).
Rebreather diver with bailout and decompression cylinders. Scuba gas management is the aspect of scuba diving which includes the gas planning, blending, filling, analysing, marking, storage, and transportation of gas cylinders for a dive, the monitoring and switching of breathing gases during a dive, efficient and correct use of the gas, and the provision of emergency gas to another member of ...
