"Nitrox 32", or EAN 32, would be a nitrox blend with 32% oxygen and 68% nitrogen. This is a popular recreational blend for dives to depths up to 33 metres (108 ft). The nitrogen in the mixture is almost always provided by topping up the cylinder with air to the filling pressure.
Enriched Air Nitrox" or "EAN", and "Oxygen Enriched Air" are used to emphasize richer than air mixtures. [3] In "EANx", the "x" was originally the x of nitrox, [11] but has come to indicate the percentage of oxygen in the mix and is replaced by a number when the percentage is known; for example, a 40% oxygen mix is called EAN40. The two most ...
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).
nitrox. Also: "Enriched Air Nitrox (EAN)" Main article Nitrox. Mixture of nitrogen and oxygen for use as breathing gas. Usually with oxygen percentage higher than air. nitrox stick. See: Gas blending for scuba diving#Mixing the gases. A mixing tube used to blend oxygen with air before compressing to make nitrox breathing gas.

Equivalent narcotic depth (END) (historically also equivalent nitrogen depth) is used in technical diving as a way of estimating the narcotic effect of a breathing gas mixture, such as nitrox, heliox or trimix. The method is used, for a given breathing gas mix and dive depth, to calculate the equivalent depth which would produce about the same ...
