Nitrox is air with extra oxygen added. The air you breath on the surface is 79% nitrogen and 21% oxygen roughly speaking, with a couple other gases mixed in there in minute quantities. As you should have learned in your BOW class, nitrogen is a concern when diving, it is the reason for the dive tables (residual nitrogen). Nitrogen is not used by your body, therefore the nitrogen that you take in when you dive is disolved in your tissues until you make an accent. Nitrogen is the gas that causes "the bends". Therefore it makes sense to replace some ofthe nitrogen in the air we breathe, with another gas. Adding Oxygen to the air (a gas we need to keep every cell in our body running) makes you feel less tired. Also using this gas extends your bottom time over those you have when using air.sploosh21:just wondering.
scubapolly:I always encourage divers to get Nitrox certified as soon as possible, this is even more important for divers 40+.
That's interesting!! Could you explain this a little further? I'm 52 years old and Nitrox certified, but I normally dive air. Are you saying that it would be better for me to dive Nitrox most of the time - if I can get it?scubapolly:I always encourage divers to get Nitrox certified as soon as possible, this is even more important for divers 40+.
