What does the acronym "EANx" stand for?

The acronym "EANx" stands for Enriched Air Nitrox. This term is commonly used in diving to refer to a type of breathing gas that contains a higher percentage of oxygen than regular air, which is comprised of roughly 21% oxygen and 79% nitrogen. In the context of enriched air, the "x" in "EANx" represents the percentage of oxygen present in the mixture. For example, EAN32 would indicate a mixture that contains 32% oxygen.

Using enriched air nitrox allows divers to extend their bottom times and reduce their nitrogen absorption during dives, thereby minimizing the risk of decompression sickness. It is an important concept in diving training, particularly for divers seeking to improve their safety and efficiency during dives at various depths. Understanding the terminology associated with enriched air nitrox, including the acronym EANx, is essential for divers who are trained in this practice.
