Helium is substituted for nitrogen in the air used by deep sea divers for breathing because Helium is sparingly less soluble in blood, unlike Nitrogen which is more soluble in blood.

Helium is just mixed to reduce the solubility of nitrogen into the blood at extreme depth underwater.
Otherwise, it causes bents (pain due to sudden evaporation of nitrogen when diver comes out of water).

It is used as a diluent for oxygen in modern diving apparatus because of its very low solubility in blood.

Air which was first used in diving tanks contains roughly 20% oxygen and 80% nitrogen.
