The use of gas mixtures in the diving industry
Water normally contains oxygen, humans do not have gills and therefore cannot breathe and survive underwater without the help of external devices. Researchers in the early days of diving quickly realized that the supply of air from the surface and its breathing It is not easily possible under water and in order not to put too much pressure on the divers' chest and lungs, the diver's breathing air, which is provided by special regulators, should be almost the same as the pressure of the surrounding environment so that the lungs can easily contract and expand. Muscle expansion and air breathing.
Mixed gases used in diving
Breathing Air compressed air
It is not possible to use pure oxygen gas for divers. Oxygen becomes toxic at great depths, and long-term exposure to pure oxygen can be fatal, for this reason, oxygen and nitrogen gas mixtures (breathing air) are not used for diving at low depths. The reason for using this gas in the depths is that it reduces the laxity and lowers the level of consciousness of the diver when inhaling nitrogen gas.
Nitrox
The most used mixture in the diving industry is Gasinitrox mixture, which is also known as enriched air. Breathing enriched air often has 32% to 36% oxygen, and as a result, less nitrogen enters the diver's body by breathing this gas. In this case, decompression sickness or relaxation in divers is reduced and the time of remaining in the depths for the diver is increased.
Heliox gas
Heliomax gas is a gas mixture that consists of a combination of helium gas and oxygen gas and is widely used in the medical and diving industries. When helium is completely replaced by nitrogen, it is called Heliox gas mixture. (It contains 21% oxygen and 79% helium.) Heliox is like air, but it has a much lower density than air. Also, this gas is used in the treatment of asthma and shortness of breath because it will make inhaling and exhaling easier. For this purpose, less energy is spent on breathing.
By using the technical knowledge of its engineers, Gasardestan Company is able to produce Heliox gas in large bundles and capsule pallets in different volumes. For more information, contact us.
