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.

At first nitrogen was used but since it dissolves in the blood when the pressure is high and becomes toxic, so helium is used as it does not dissolve in the blood and is non toxic.

As deep sea divers are under very high pressure of water, at that pressure oxygen are not able to dissolve in our blood so helium is used to fulfill the requirement.

Nitrogen is a toxic gas which can't burn but mix with blood. It makes the blood toxic and when the divers comes out, their vessels bursts but helium does not react.

Oxygen get solid state under high pressure. So, it does not dissolve into blood under high pressure existing in the deep sea. Helium helps to keep it gas state.

A mixture of 80% helium and 20% oxygen is used as an artificial atmosphere for deep-sea divers and others working under pressurised conditions.

Helium is the lightest gas and does not cause any harm to the body that's why it is used by deed divers. Thanks.

Nitrogen react with blood vessels and causes bends. While helium is inert gas does not reacts with bloods.

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

Argon and Krypton being inert gases can't be used since they dissolve in blood with increasing pressure.
