So what is Enriched Air Nitrox? In the broadest sense, Enriched Air is any gas blend of oxygen and nitrogen other than air. Air, of course, is basically a mix of 21 percent oxygen and 79 percent nitrogen. For divers, Enriched Air is any gas blend with more than 21 percent oxygen. Generally for recreational divers this is a blend of either 32 percent or 36 percent oxygen, sometimes abbreviated EANx32 or EANx36.

As we all know, nitrogen is the cause of diving maladies such as decompression sickness and nitrogen narcosis. We learned in our Open Water Diver course that our bodies use up oxygen when we breathe. However, because nitrogen is not used by our bodies, nitrogen saturates our tissues. This happens whether we are on the surface or on a dive.

Our regulators are designed to deliver air to us at whatever pressure we are at. That’s why our bottom times become shorter and shorter the deeper we go. As our regulators deliver more and more air to us as we descend, more and more nitrogen is absorbed into our tissues. The more nitrogen we absorb on a dive, the more dangerous and difficult it becomes for us to return to the surface.

Why? The answer is simple. While we can tolerate some excess of nitrogen in our tissues, exceeding the safe limits prescribed by our dive tables and computers can result in the dissolved nitrogen in our tissues coming out of solution and forming bubbles that produce symptoms such as joint pain, coughing, rashes, headaches, paralysis, unconsciousness, or worse. This is what we divers call decompression sickness and our non-diver friends call the bends.

Enriched Air became more and more popular and in our days it's essential to professional and recreational divers. Today the Enriched Air Diver course is the most popular specialty scuba diving course, and it’s easy to see why. Scuba diving with EAN gives you more no decompression dive time. This means more time underwater, especially on repetitive scuba dives. On top you increase your safety, shorten your surface interval and feel less tired.
