What percentage of oxygen is found in traditional Nitrox blends?

In traditional Nitrox blends, the most commonly used mixtures for recreational diving are EAN32 and EAN36. These blends contain 32% and 36% oxygen, respectively. The choice that states 32% and 36% accurately reflects the percentages of oxygen in these widely recognized Nitrox mixtures.

Understanding the composition of Nitrox is crucial for divers, as it impacts the depth and duration of dives and requires different handling and planning compared to traditional air. The higher oxygen content in Nitrox diminishes the amount of nitrogen absorbed by the body, reducing the risk of decompression sickness, which is a major benefit for divers choosing this type of gas mixture over regular air.
