2. Gas blending for scuba diving - Wikipedia

   en.wikipedia.org/wiki/Gas_blending_for_scuba_diving

   Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non-air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis , and may improve ease of breathing .

   The pressure vessel is a seamless cylinder normally made of cold-extruded aluminum or forged steel. [5] Filament wound composite cylinders are used in fire fighting breathing apparatus and oxygen first aid equipment because of their low weight, but are rarely used for diving, due to their high positive buoyancy.
