Nitrox is a blended breathing gas used by commercial and recreational divers, containing more than the 21 percent oxygen found in atmospheric air. The higher oxygen content reduces the nitrogen fraction, which allows divers to stay at depth longer without accumulating dangerous levels of nitrogen in their tissues. Using it requires specialized certification, dedicated cylinders, and oxygen-clean regulators to prevent combustion.
