NITROX refers to any gas mixture composed of nitrogen and oxygen; including normal air which is approximately 78% nitrogen and 21% oxygen
The most common use of NITROX mixtures containing higher than normal levels of oxygen is in SCUBA diving where reducing the proportion of nitrogen by increasing the proportion of oxygen reduces the risk of decompression sickness, allowing extended dive times without increasing the need for decompression stops .
The reduced percentage of nitrogen reduces nitrogen build up in the body's tissues and extends the possible dive time and/or reduces the risk of decompression sickness (also known as the bends ). Other names for NITROX include: Enhanced Air Nitrox, Oxygen Enriched Air, Nitrox, EANx or Safe Air.
