At EspriGas, we make understanding medical gas simple, so you can provide the best patient care. 

Common Medical Gases 

Oxygen (O2)

As a vital gas used in hospitals, clinics, surgeries and intensive care wards, oxygen is used to treat individuals with lung diseases and to treat hypoxemia and hypoxia. Because oxygen expands 600 times from liquid to gas, large amounts are usually transported as a liquid. 

Common sizes: 

Oxygen E, H, Vertical Gas Liquid (VGL) 180 and Micro-Bulk

Nitrogen (N2)

Used as a shielding gas for packing medicines, medical nitrogen gas is also used to dry medical equipment. In liquid form, it’s used to keep cells alive during study and is also used to freeze-off moles in dermatology practices. It even can be used to pre-cool some MRI machines and kill diseased tissue in cryosurgery. 

Common sizes: 

Nitrogen H, T, E and VGL 230, 180, 160
