What are the common Nitrox mixtures used in diving?

The most commonly used Nitrox mixtures in diving are indeed EAN32 and EAN36. These mixtures represent enriched air nitrox blends that provide a higher oxygen content compared to regular air, which contains approximately 21% oxygen and 79% nitrogen.

EAN32, for instance, has 32% oxygen and is favored because it offers a good balance between reducing nitrogen exposure while maintaining a manageable level of oxygen for safe diving. Similarly, EAN36 contains 36% oxygen and is utilized for deeper dives, allowing divers to extend their bottom times while reducing the risk of nitrogen narcosis.

By using these mixtures, divers can plan their dives to maximize safety and minimize the risks associated with nitrogen saturation, making EAN32 and EAN36 widely adopted choices in recreational diving.
