| Application: |
| The mixture gas of helium and oxygen is used as breathing gas for divers who must work at great depths and therefore high pressures. The use of helium to dilute the oxygen instead of nitrogen, as in air, prevents nitrogen being dissolved in the blood, which is the cause of nitrogen narcosis (also known as "bends"). |
