What is Nitrox?
Nitrox is any combination of oxygen and nitrogen. The air you breathe today is a form of Nitrox, which is 79% nitrogen and 21% oxygen. Nitrox mixtures with greater than 21% oxygen are referred to as Enriched Air Nitrox (EANx). The “x” refers to the percentage of oxygen in the mixture. The most commonly used Nitrox mixtures are EAN32 (32% oxygen and 68% nitrogen) and EAN36 (36% oxygen and 64% nitrogen).
