If there is one scuba specialty course that every diver should have, it is Enriched Air Nitrox.

Along with the Open Water Diver certification, Nitrox is one of the most popular scuba certifications worldwide. Visit almost any dive destination and you will find Nitrox available on dive boats, liveaboards, and dive resorts.

What Is Nitrox?

Nitrox is a breathing gas containing more oxygen and less nitrogen than regular air. The most common recreational blend is Enriched Air Nitrox 32 (EAN32), which contains 32% oxygen and 68% nitrogen.

Because Nitrox contains less nitrogen than regular air, divers absorb less nitrogen during their dives.

Why Is Less Nitrogen Important?

The lower nitrogen content provides several important benefits.

Longer Bottom Times

Because your body absorbs nitrogen more slowly, Nitrox can increase your available no-decompression time.

Shorter Surface Intervals

Less nitrogen loading can allow for more efficient repetitive diving.

Added Safety Margin

Many divers choose to dive Nitrox while keeping their computer set to air settings.

This conservative approach provides an additional safety margin by reducing nitrogen exposure while maintaining the same dive profile.

The Most Common Nitrox Blend Worldwide

EAN32 is by far the most commonly available Nitrox blend throughout the diving industry.

Whether you are diving in Costa Rica, the Caribbean, Egypt, Indonesia, Thailand, the Maldives, or on a liveaboard, EAN32 is often the standard Nitrox option.

That means a Nitrox 32 certification will allow you to use the gas blend you are most likely to encounter during your travels.
