Few things have revolutionized recreational diving in the past decade as much as the introduction of Enriched Air Nitrox (EANx). Nitrox is simply air with additional oxygen added to reduce the concentration of nitrogen. While the additional oxygen offers no benefit in and of itself (and can, in fact, pose additional risk at depth), breathing less nitrogen provides divers with several benefits:
- Longer no-decompression limits
- Shorter surface intervals
- Reduced risk of decompression sickness
- Reduced fatigue after dives
- May also improve gas consumption
What Is Involved? There are no required dives and no pool time for the PADI Enriched Air Nitrox Course. Some of the topics that will be covered are: EANx equipment, Enriched Air settings on your computer, managing oxygen exposure, analyzing EANx cylinders, EANx diving emergencies, and more.
- Self-Study – You will need to review a small manual, complete the knowledge reviews, and watch the EANx DVD.
- Classroom – The classroom discussion will review and expand on what you’ve learned on your own. Then you will get to practice analyzing EANx cylinders and see how an EANx cylinder is filled at the filling station.
What Equipment Is Required? You will need to bring your PADI Enriched Air Nitrox Crewpack and your Open Water RDP (Recreational Dive Planner). If you own an EANx compatible dive computer, you may bring it to the class to practice EANx setup and dive planning.
