Enriched Air Nitrox (EANx)

What’s in a name: Nitrox, EANx, SafeAir, NNI and NNII, Enriched Air Nitrox (EANx).. Its all the same stuff. Depending on the store that you are going into the name that is used may be different. It all should be, as is the case with air (21% mix), clean, free of moisture and free of contaminates.

Sound Dive Center is the first Dive Center in the Puget Sound to teach and provide Nitrox commercially to the recreational diver (1993). We have taught Nitrox Specialty classes to the Military, National Parks (Olympic) Rangers, Diving safety officer(s) at Battle NW, plus over a 1000 recreation divers. We even teach Instructors how to teach Nitrox to their students.

Nitrox will increase your bottom time for some depths, to over double your AIR time. It decreases the amount of Nitrogen that “on gasses” into your body, and subsequently increases the amount of O2 that “on gases” into your tissues. This tends to make you feel much better after a dive. There are some risks involved with breathing a gas mix with higher oxygen content which is why it is important to go through the course first to understand how your body reacts and what safety measures out to be put in place when planning your Nitrox dives.
