Abstract. Helium, being very inert from a biochemical point of view and having a density seven times lower than that of nitrogen, allows for superior performance by eliminating the effects of narcosis and breathing difficulties. By developing decompression tables specially adapted to this new HELIOX (helium-oxygen) breathing mixture, the depth limits imposed by air have been considerably exceeded and divers have been able to reach depths of 150 m.
