Used in Scuba diving. It is a a breathing gas consisting of air mixed with a higher percentage of oxygen than normal air (40% and above is uncommon within recreational diving). The two most popular blends is EANx32 and EANx38 (also named Nitox I and Nitrox II).
There are several ways of mixing Nitrox. One can fill some pure oxygen onto a tank and then fill with air to make the wanted mix. Other ways is to remove nitrogen then filling air with a special filter/membrane or have it premixed industially amogst other.
Using EANx means that the rate of nitrogen absorption into the body is reduced. So the length of time a diver can remain at depth without requiring decompression increases (115 minutes versus 55 minutes at 60 feet) and the risk of [decompression sickness]? is reduced by lowering the nitrogen levels within the diver's body tissues.
Warning: Diving with Nitrox og dealing with nitrox fills araises lots of potetially fatal dangers due to the high partial prssure of oxygen. Tanks may explode if treated improper.
It is not a deep-diving gas mixture.
