What does EANx stand for in diving terminology?

EANx stands for Enriched Air Nitrox in diving terminology. This term refers to a gas mixture that contains a higher percentage of oxygen compared to regular air, which typically comprises about 21% oxygen and 79% nitrogen. Enriched Air Nitrox generally has oxygen content between 22% and 40%.

Diving with EANx allows divers to extend their no-decompression limits and reduce the risk of nitrogen narcosis, making it a popular choice for divers who are looking to enhance their underwater experiences. By using a blend that has more oxygen, divers can optimize their bottom times at certain depths while experiencing less fatigue during and after dives.

Understanding this terminology is essential for divers to correctly plan their dives and ensure they are using the appropriate mixtures for their recreational or safety needs.
