First, high altitude hypoxia
Hypoxia refers to the pathological process of abnormal changes in metabolism, function and morphological structure of tissues due to insufficient oxygen supply or oxygen use disorder. Hypoxia is a very common pathological process in various clinical diseases, and hypoxia in important organs such as brain and heart is also an important cause of death.
In addition, the obvious decrease of arterial oxygen content leads to insufficient oxygen supply to tissues, which is also called hypoxemia.
Second, ultraviolet light.
When ultraviolet rays irradiate human body or organism, physiological changes occur, and after irradiation, the skin turns black and has obvious pigmentation, which will cause skin cancer.

Hypoxia treatment method
1. Chemical oxygen production
Based on the principle that chemical reaction of chemical substances produces oxygen, manganese dioxide and potassium chlorate are often used.
The oxygen supply mode of oxygen generator is mostly used for environmental hypoxia symptoms to improve the influence of hypoxia environment on the body.
You can choose different methods to improve hypoxia according to your own situation.
Second, liquid oxygen therapy
Use a biologically effective oxygen solution to bypass the respiratory tract and directly absorb oxygen through mucous membrane, digestive tract and skin. This method is especially suitable for patients with respiratory diseases who need to supplement oxygen due to lack of oxygen, but it is inconvenient to supplement oxygen, such as plateau tourists. This is a milestone of oxygen supplement technology, which breaks through the life bottleneck that oxygen supplement can only breathe through the lungs.
