The 22nd China International Hospital Construction, Equipment and Management Exhibition, which was repeatedly postponed due to the Covid 19, finally ended on October 16, 2021 successfully.

Although it is easy to understand that altitude is inversely proportional to oxygen content, it is not enough to only know these, because it needs strict calculation to know how to select the capacity of oxygen generator at a specific altitude is the most appropriate;

​The molecular sieve, the core component of the PSA oxygen generator, is a porous material that can screen substances at the molecular level, and is mainly composed of zeolite materials. Because it can filter gases of different diameters at the molecular level, people take advantage of this feature and use it to adsorb specific gases, such as oxygen. This is also the core principle of the PSA oxygen generator.

In medical oxygen, different pressures are given according to different oxygen uses.

In plateau areas, the higher altitude, the lower oxygen content in the air, and then hypoxia will make people feel uncomfortable. Although this problem can be lightened by oxygen uptake, the amount of oxygen inhaled is not the more the better, and it requires a scientific ratio.

Oxygen is widely used in industrial fields, such as metallurgical combustion, chemical industry, medical treatment,...
