What is a key advantage of using EAN32 for Nitrox diving?

Using EAN32, or Enriched Air Nitrox with a 32% oxygen concentration, offers a significant advantage in providing a favorable balance of extended bottom time and depth. The higher oxygen content compared to regular air (which is about 21% oxygen) allows for reduced nitrogen absorption in the body, which means divers can spend more time at a given depth without accumulating excessive nitrogen that could lead to decompression sickness.

This characteristic is particularly beneficial for recreational diving, where extended bottom time is often desired. EAN32 is commonly used for depths up to around 100 feet, where it optimally balances the benefits of increased oxygen to promote longer dives while still being in a safe range concerning oxygen toxicity.

This choice aligns with the goals of divers who seek to maximize their time underwater, making EAN32 one of the preferred mixtures for typical recreational dive profiles. Other options do not accurately reflect the realities of Nitrox diving; for instance, it does not eliminate oxygen exposure risks, nor is it the only mixture suitable for deep dives.
