Nitrox Diving: What Is It and Why You Should Get Certified
The thrilling benefits of Nitrox make it a must-have certification for divers of all levels
The PADI Enriched Air Diver Speciality Course is a quick and affordable certification that brings scuba diving to a new and exciting level.
Because of the many perks associated with Nitrox, it is no surprise that it is the most popular PADI speciality course.
So, what is Nitrox and what makes it so appealing?
What Is Nitrox and How Does It Work
Commonly known as Nitrox, the term is an abbreviation of Enriched Air Nitrox (EANx).
Compared to normal air used in scuba tanks (78% nitrogen, 21% oxygen), enriched air is a 22%-40% oxygen and nitrogen gas blend.

Benefits of using Nitrox
As you have learnt from your dive training, when you dive your body absorbs nitrogen.
By making a safety stop and the end of each dive and always making a slow ascent, you are giving your body time to eliminate the excess nitrogen, thus minimizing the risks of decompression sickness.
With nitrox, you are breathing more oxygen and – consequently – less nitrogen. This has a strong ripple effect on different aspects of diving:
Extended allowable bottom time
The reduced percentage of nitrogen that you breathe with nitrox allows divers to extend their no decompression time. This means spending more time underwater!
Depth | Air No decompression Limit | EANx32 No decompression Limit | EANx36 No decompression Limit |
18 metres | 56 min | 95 min | 125 min |
22 metres | 37 min | 60 min | 70 min |
Dive table: EANx32 and EANx36 consist of 32% and 36% oxygen, respectively.
Compared to normal air, Nitrox significantly extends the no decompression limit and can even double the allowed bottom time.
Shorter Surface Intervals
If you are doing more than one dive in a day, breathing and absorbing less nitrogen equals shorter surface intervals needed to “off gas” before it is safe to dive again.
Longer Dive Times
For divers who use normal air, doing repetitive dives means shorter dive times. This can be especially disappointing if you wish to explore an exciting dive site.
With nitrox, however, you can enjoy longer dive times because you have less residual nitrogen in your body.
Less Exhaustion
Have you ever felt tired and drowsy after a heavy diving schedule? Although it is not scientifically proved, many divers report feeling more alert when diving with Nitrox.
