What diving risk is minimized by using Enriched Air Nitrox?

Using Enriched Air Nitrox primarily minimizes the risk of decompression sickness. The reason behind this is the reduced concentration of nitrogen in Enriched Air Nitrox compared to regular air. When divers breathe air, approximately 79% of it is nitrogen, which is an element that dissolves into the body tissues when under pressure. As a diver ascends, the nitrogen that has been absorbed can form bubbles if the ascent is too rapid or if the diver exceeds certain limits.

Enriched Air Nitrox, typically with a higher oxygen percentage, decreases the partial pressure of nitrogen in the breathing gas. This leads to less nitrogen being absorbed into the body at given depths, effectively reducing the risk of nitrogen bubbles forming during ascent. Therefore, utilizing Enriched Air Nitrox allows divers to extend their no-decompression limits and provide greater safety margins against developing decompression sickness.

While air embolism and high pressure nervous syndrome are significant risks associated with diving, they are not directly mitigated through the use of Enriched Air Nitrox like decompression sickness is. Understanding the effects of nitrogen and how different gas mixtures influence these risks is key for divers looking to enhance their safety while diving.
