Diffusion oxygen supply to relieve plateau hypoxia symptoms

The plateau has a special natural environment, which is characterized by low pressure, low oxygen concentration, dry and cold climate, high wind speed, and significant increase in solar radiation and ultraviolet radiation. In the plateau environment, as the altitude increases, the oxygen partial pressure in the air continues to decrease. If people stay in this hypoxic environment for a long time, hypoxaemia may be developed in severe cases .

Human nerve tissue is sensitive to internal and external environmental changes. Therefore,under hypoxic conditions, the brain function damage occurs earlier and is severe. The longer the exposure time is, the more severe the damage can be caused, especially for sensation and memory. The bad effects on cognitive functions such as thinking and attention is serious and long lasting.

Researchers have found that the effects of plateau hypoxia on human sensory functions appear earlier, and the eyesight is more sensitive to hypoxia. At altitude above 4300 meters, night vision is seriously impaired, and this damage will not be lessened due to the body's compensatory response or lowering the altitude.

The auditory function of the human body will also be affected as the altitude increases. At about 5000 meters above sea level, people’s hearing loss in the frequency range is apparent; 5000 to 6000 meters, people’s hearing in the middle and low frequency range is seriously reduced, and the direction of hearing is also badly affected. This may also be the important reason for accidents under plateau hypoxia conditions. In addition, the human body's sense of touch and pain will gradually become dull during severe hypoxia, and delusions and hallucinations may occur at extreme heights.

Acute plateau hypoxia will seriously affect people's thinking ability. Researchers believe that the danger of hypoxia's impact on thinking ability lies in the contradiction between subjective perception and objective impairment. For example, hypoxia has caused serious damage to the individual’s thinking ability, but they are often unaware of that, and they think that their thinking and working ability are normal. In addition, acute plateau hypoxia can also cause people's attention to be seriously affected. When the altitude is above 5000 meters, it is difficult for people to concentrate, and it is impossible to concentrate on doing one thing as usual. Moreover, as the altitude increases and the degree of hypoxia increases, the range of attention will become narrower and narrower.

Researchers pointed out that the special environmental characteristics of the plateau have obvious effects on the body's physiological and psychological activities. The way to relieve hypoxia is to provide oxygen. For example, to equip people who enter the plateau for the first time with an oxygen supply device, which helps to reduce the risk of cognitive decline caused by hypoxia to a small degree. Humans have an adaptation process to hypoxia, which generally takes 1 to 3 months. Therefore, before entering the plateau, they must be exposed to the environment at different altitudes in a planned and intermittent manner, so that the body has enough time to compensate for environmental changes to alleviate and eliminate various symptoms caused by hypoxia.

It is confirmed that oxygen inhalation can quickly and effectively relieve fatigue in a short time, improve and enhance the working ability of the human body and the brain. Persistent oxygen inhalation has a significant protective effect on the important organs of plateau residents. People doing important construction or military operations in plateau areas need sufficient physical and mental preparation, and people after work and activities need to inhale oxygen, too. The quick recovery of physical and mental strength from oxygen inhalation has a very convenient and reliable value. In addition, with the rapid development of tourism, industry and commerce, personnel exchanges and contacts in various regions have been increased day by day, but plateau sickness is a lingering trouble for every person who goes to plateau areas. With the popularization of oxygen inhalation and oxygen therapy knowledge, it can significantly improve the experience of tourists, industrial and commercial people in plateau areas, in order that people in the plateau enjoy the oxygen environment of the plains and even the sea level. We strongly believe that through the improvement and application of this technological method, the human dream of transforming and conquering nature will definitely become the main development direction of improving the life quality of people in the Plateau at present and even in the future  

Since 2013, Longfian has been focusing on providing oxygen supply solutions to plateau areas. The self-developed diffusion oxygen supply system for plateau supports 24 hours continuous operation and long-term high-concentration oxygen supply, which meets the oxygen supply needs of major hotels, military camps and other public places in plateau areas such as Tibet and Qinghai in China.
