Enriched Air Nitrox
What is Nitrox?
Nitrox is actually any combination of Nitrogen and Oxygen. Regular breathing air is comprised of approximately 21% Oxygen and 79% Nitrogen. Nitrox mixtures with oxygen percentages greater than 21% are called Enriched Air Nitrox (EANx).
Why PADI Enriched Air Diver?
The PADI Enriched Air Nitrox Diver course is one of scuba diving’s most popular specialties, and it’s easy to see why. Scuba diving with Nitrox gives you more no-decompression dive time. This means more time beneath the surface, especially on repetitive scuba dives. While some people use Nitrox to also shorten their surface interval time, we believe you should still relax and enjoy some R&R for at least an hour between dives.
There are many benefits to diving on Enriched Air Nitrox, but there are also restrictions. This course will teach you everything that’s needed to safely dive on Enriched Air Nitrox, analyze the oxygen content in a scuba tank, and adjust a dive computer to account for Enriched Air Nitrox.
• Extended bottom times
• Shorter surface intervals
• Shorter decompression stops
• Less post dive fatigue
• More dives per day possible
• Nitrogen loading declines as per mix
• Reduced chance of Decompression Sickness
• Reduction in Nitrogen Narcosis
• Safer dives!
Diving with Enriched Air, rather than standard air, extends your no decompression limits. This means more time underwater! For example, if you dive to 15 metres/50 feet on air, your no decompression limit is 80 minutes. But, diving on 36% Enriched Air gets you 220 minutes of no decompression time – an increase of 140 minutes.
