What Is Respiratory Hypoxia?

Hypoxia (hypoxia) refers to a pathological process that causes abnormal changes in the metabolism, function, and morphology of a tissue due to insufficient oxygen supply or impaired oxygen use. Hypoxia is a very common pathological process in various clinical diseases. Hypoxia of vital organs such as brain and heart is also an important cause of death. In addition, due to the marked decrease in arterial blood oxygen content, the tissue is insufficiently supplied with oxygen, which is also called hypoxemia.

Hypoxia (hypoxia) refers to

The body's uptake and utilization of oxygen is a complex biological process. In general, judge the organization's access to and use of oxygen

According to the causes of hypoxia and the characteristics of blood gas changes, simple hypoxia can be divided into four types:

2.1 hypotonic hypoxia

The body inhales oxygen and transports it to the tissue through the blood, where it is eventually felt and utilized by the cells. Therefore, the nature of hypoxia is a response and adaptive change of cells to hypoxia. In acute severe hypoxia, the main changes in cells are mitochondrial energy metabolism disorders (including toxic hypoxia in tissues); chronic mild hypoxia cells are mainly compensated by the regulation of oxygen receptors.

3.1 Compensatory changes 3.1.1 Changes in cell energy metabolism during hypoxia

(1) Enhancement of anaerobic digestion: When Pa O2 decreases, when P O2 around mitochondria is lower than 0.04 to 0.07kPa, oxygen as the final electron acceptor of the aerobic oxidation process will be in shortage, and mitochondrial aerobic metabolism will be impaired. , ATP production decreases, and ADP increases in the cytoplasm. Increased ADP in the cytoplasm enables

The effect of hypoxia on the organ depends on the degree of hypoxia, the duration of the speed and the functional metabolic status of the body. Chronic mild hypoxia mainly causes organ compensatory reactions; acute severe hypoxia, organs often have modern insufficiency and dysfunction, and even cause irreversible damage to important organs, leading to death of the body.

Physical oxygen generation

Through the pressure swing adsorption of molecular sieve, the oxygen and nitrogen in the air can be directly separated at normal temperature to extract high-purity medical oxygen, which can realize continuous and uninterrupted oxygen supply.

The method is suitable for people with different levels of physiological hypoxia, such as middle-aged and elderly people, poor people, pregnant women, college entrance examination students, and obese people. It can also eliminate fatigue and restore physical function after heavy physical or mental exhaustion. To a certain effect.

2. Chemical oxygen production

The principle of generating oxygen by the chemical reaction of chemical substances, mostly using manganese dioxide and potassium chlorate.

The oxygen supply method of the oxygen generator is mostly used for the symptoms of environmental hypoxia and improving the impact of the external environment on the body.

You can choose different methods to improve your own hypoxia according to your own situation.

Liquid oxygen therapy

Use a bioavailable oxygen solution to bypass the respiratory tract and absorb oxygen directly through the mucous membrane, digestive tract, and skin. This method is especially suitable for patients with respiratory diseases. Hypoxia requires oxygen supplementation, but people with inadequate oxygen supplementation, such as plateau tourists. This is a milestone in oxygen supplement technology, breaking through the bottleneck of life that oxygen supplement can only breathe through the lungs.
