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.

Deep sea divers take oxygen mixed with inert gas say He and adjust the partial pressure of oxygen according to the requirement. Actually, in sea after every 100 feet depth, the divers experiences approximately 3 atm pressure, subnormal air cannot be breathed in depth of sea, moreover, the pressure of n2 increases in depth of sea and it diffuses in the blood.

In past time hydrogen is added with nitrogen,they react with each other & forms NH3. Under deep sea, the solubility of the NH3 gas increase with pressure or water head. that NH3 dissolve in blood. when person comes out from sea then concentration of NH3 bubbles produce pain in his body.

Helium is non toxic and lightest gas in inert gasses.

Helium is a non toxic that doesn't react with blood.

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

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.

Helium is not harmful for humans and it work like oxygen in the depth of the sea.

Helium is helpful to prevent the mixing of air in blood vessels and divers safe from death region.

Yeah is true helium is helpful to resist the mixing of air in blood.
