Enriched Air Nitrox Course

An Enriched Air Diver is a certified scuba diver trained to use Enriched Air Nitrox (EANx)—a breathing gas with a higher oxygen content and lower nitrogen content than regular air. This allows for longer bottom times, shorter surface intervals, and potentially less fatigue after diving. Enriched Air (commonly 32% or 36% oxygen vs. 21% in regular air) reduces nitrogen absorption, lowering the risk of decompression sickness and enabling more dives in a day. However, it requires specialized training, as using higher oxygen levels involves specific safety procedures and equipment considerations. The PADI Enriched Air Diver course is one of the most popular specialty certifications for divers looking to maximize their underwater time safely.
