The benefits of using Enriched Air Nitrox are your choice. You can either extend your bottom time with longer no-decompression limits, have shorter surface intervals, or use air tables to be more conservative.
What will I learn?
Your Enriched Air Nitrox theory class will be one of the most informative of all recreational courses. You will learn new dive medical terms like “oxygen toxicity”, “equivalent air depth”, and reinforce knowledge about terms like “gas partial pressure”, and “decompression sickness” taught in your open water course. You will learn how to analyze your gas mixture, label your nitrox tanks, and also to use different methods to plan a nitrox dive.
Is it safe?
For a while Enriched Air Nitrox was the misunderstood genius. Higher concentrations of Oxygen can become toxic at depth and cause convulsions underwater. Now that this is understood, we set Maximum Operating Depths to prevent Oxygen Toxicity, thus minimizing risk. Just like watching your tank pressure, you should always monitor your depth.
