Nitrox is a gas mixture made up of nitrogen and oxygen (and sometimes trace gases).[Brubakk and Neuman] Breathing air contains 78% nitrogen, 21% oxygen, and 1% trace gases, with argon being the highest portion. Nitrox is commonly used in scuba diving, with the most common mixes containing 32% or 36% oxygen. Early studies found that the increased oxygen had no significant reduction of the effect of decompression sickness (ie the bends)[1]. Divers may use nitrox tables or a nitrox-capable dive computer to determine their decompression requirements.
