What is the common range of oxygen percentages for recreational Nitrox mixes?

The common range of oxygen percentages for recreational Nitrox mixes is typically between 32% and 36%. This range is popular among divers because it allows for reduced nitrogen absorption, which can lead to longer bottom times and decreased risk of decompression sickness. The increased oxygen content in these mixes also enhances the diver's overall experience, particularly at shallower depths where the advantages of using Nitrox are most significant.

In recreational diving, the most widely used Nitrox mix is EAN32 (32% oxygen) and EAN36 (36% oxygen), as they provide a good balance between the benefits of added oxygen and the potential risks of higher oxygen partial pressures. This range is within safe operational limits for most recreational diving activities, making it ideal for divers who are seeking to extend their dive times and enhance safety.
