What is the typical oxygen content of EANx 32?

The typical oxygen content of EANx 32, or Enriched Air Nitrox with 32% oxygen, is indeed 32% oxygen and 68% nitrogen. This mixture is designed specifically for recreational diving to allow divers to extend their bottom time while also reducing nitrogen absorption, which can help minimize the risk of decompression sickness. When using EANx 32, divers benefit from a lower percentage of nitrogen in the mix compared to regular air, which contains approximately 21% oxygen and 79% nitrogen.

Understanding the composition of EANx is crucial for divers, as it influences the dive profile, allowable depth limits, and the necessary adjustments to dive tables or computers. Therefore, knowing that EANx 32 is composed primarily of 32% oxygen and 68% nitrogen is essential for safe diving practices and proper planning during dives.
