The term "mix" in EANx diving specifically refers to the specific ratio of oxygen and nitrogen in the breathing gas used during the dive. In the context of enriched air nitrox, this mix typically indicates that the gas contains a higher percentage of oxygen compared to regular air, which consists of approximately 21% oxygen and 79% nitrogen. The increased oxygen content in the mix helps divers extend their no-decompression limits and can reduce nitrogen uptake, thereby lowering the risk of decompression sickness. Understanding the mix is crucial for divers to manage their dive plans effectively, including how long they can dive at specific depths while remaining within safe exposure limits to oxygen and nitrogen. This concept is foundational for divers who are trained to utilize enriched air safely and efficiently.
