Domestic oxygen generators are mainly one-liter and two-liter oxygen generators, but the maximum gas production of this kind of oxygen generator can reach five liters, and the oxygen concentration is about 90% 3%. The oxygen concentration of domestic oxygen inhalers is within the oxygen concentration range.

The oxygen concentration of the oxygen generator needs to be adjusted according to the situation. The concentration of oxygen inhalation for general patients is 29-37%, while that for critically ill patients with acute hypoxia is 37-45%. The oxygen flow rate of most patients with hypoxia is 2-4 liters/minute, so the oxygen concentration can reach 29-37%. Be cautious about high-flow oxygen supply, generally only for patients with severe hypoxia, oxygen partial pressure < 30 mm Hg and no carbon dioxide retention.

Characteristics of oxygen generator

Oxygen generator is a machine for producing oxygen, and its principle is to use air separation technology. Firstly, air is compressed at high density, and gas-liquid separation is carried out at a certain temperature by using the different condensation points of each component in the air, and then it is separated into oxygen and nitrogen by rectification. Generally speaking, because most of them are used to make oxygen, people are used to calling them oxygen generators.

Because oxygen and nitrogen are widely used, oxygen generators are also widely used in the national economy, especially in metallurgy, chemical industry, petroleum, national defense and other industries. Germany and France are the first countries to produce oxygen generators in the world. Germany Linde Company manufactured the world's largest 10 m3/s oxygen generator in 1903. Following Germany, Air Liquefaction France began to produce oxygen generators on 19 10, with a history of 100 years.
