What is Nitrox?
any combination of nitrogen and oxygen. Regular breathing air is
comprised of approximately 21% Oxygen and 79% Nitrogen. Nitrox
mixtures with percentages of oxygen greater than 21% are called Enriched
Air Nitrox (EANx). The commonly used EANx mixtures are EAN 32 (32%
Oxygen and 68% Nitrogen) and EAN 36 (36% Oxygen and 64% Nitrogen).
Special user friendly decompression tables for these EANx mixes are
available from PADI and TDI. A prudent nitrox diver would also take
advantage of a programmable nitrox computer to provide them with the added
benefit of multi-level nitrox diving.
first used in 1912 and has been used extensively since the 1960's by the
military and commercial operations and since 1985 in recreational diving.
It is also used in the medical field as a therapy gas for hyperbaric wound
care, breathing O2 at high PO2 levels under pressure has tremendous tissue
Advanced divers have been taking advantage of Nitrox for cave diving,
wreck diving, spearfishing, lobster harvests and many other diving
applications. Recreational diving agencies, like NAUI and PADI
fully recognize and sanction Nitrox as a safe alternate breathing gas.
Sea Dogs Dive Center has a NITROX Fill station
on site and uses very high quality medical grade Oxygen. About 50% of the
divers that dive with Sea Dogs on a regular basis, will dive using
NITROX. Check with us to see when the next NITROX Course is.
You must be 15 Years of age to certify as a NITROX diver.
