What is Enriched Air Nitrox (EANx)?

• A. A breathing gas mixture of carbon dioxide and oxygen
• B. A gas mixture of nitrogen and oxygen with a higher proportion of oxygen than regular air
• C. A type of scrubber used in submarines
• D. A compressed air mixture used for altitude training

Answer: (B)

Enriched Air Nitrox, abbreviated as EANx, refers to a specific gas mixture that contains a higher proportion of oxygen compared to normal atmospheric air, which is approximately 21% oxygen and 79% nitrogen. By increasing the oxygen content in the breathing gas mixture, divers can benefit from extended bottom times and reduced nitrogen uptake during dives, which helps in minimizing the risks of decompression sickness. This option accurately defines Enriched Air Nitrox and highlights its primary composition, which is essential for understanding the advantages and applications of EANx in scuba diving. Divers trained in using this gas need to be aware of the correct mixtures to avoid potential oxygen toxicity at certain depths due to increased oxygen levels. The distinct characteristics of EANx make it a popular choice among recreational divers who want to dive deeper and longer safely.
