In recreational diving Enriched Air or nitrox (or EAN) is defined by any mixture of Nitrogen and oxygen with a percentage of oxygen included between 21 and 40%.

The two most commonly used nitrox mixtures are: 32% and 36% oxygen.
In all cases the other gas in the mix, is nitrogen.

Diving with a such mixture can give you many advantages:

  • Longer no deco limits
  • Shorter surface time intervals
  • Reduced Narcosis
  • Reduced Post Diving Fatigue
  • Better gas consumption (+10%)
  • Up to 50 times cleaner than standard air
  • Additional safety with flying times and altitude diving

For example – No decompression maximum time:

Depth Padi Air Limit Nitrox Best Mix Limit
20 m 45 min 219 min
26 m 20 min 56 min
32 m 14 min 27 min

There is a lot of myths regarding nitrox and its application in recreational diving. To help you to make the difference between myth and facts, we have made the following FAQ section especially dedicated to Nitrox.

F.A.Q. nitrox

Can I go deeper with Nitrox?

No, Nitrox is mostly used on mid deep dives, ranging from 20-40 meters (~60-130 feet). The more oxygen you have in the mix, the shallower will the MOD be.

Can I use my equipment or do I need to purchase new one?

You do not need to purchase any additional diving equipment. You can use your present regulator and change between Nitrox and air provided you use a 40% mix or less. However we strongly recommend to have your regulator and BCD inflator serviced before to use Nitrox

Do I need to have a special certification to use Nitrox?

Yes, the use of Nitrox requires special training and certification in its use.For the ones who are not yet certified, Andaman Scuba offers basic Nitrox certification. nitrox 1 (PADINAUI). This course can be taken. Courses are available on all our liveaboard cruise and in our dive center in conjunction with our daytrip.

What do I need to do my course?

Entry level certificate from any diving organization (CMAS, Open Water PADI, Scuba Diver NAUI…) and a minimum age of 15 years..

Can I get decompression sickness by diving with Nitrox?

Yes, no gas nor diving table can absolutely ensure that a diver will not get decompression illness. Using Nitrox provides significant decompression advantages over air, which may help avoid decompression sickness, but with all diving there is a risk of decompression illness.

Can I still have Narcosis using Nitrox?

It might seem logical that with reduced nitrogen in the breathing mix there would be reduced nitrogen narcosis at depth. The fact is, oxygen can also be a narcotic gas when under pressure. The result is that there is no significant change in narcosis when diving enriched air Nitrox as compared to air…
