Background

Human life activities cannot be separated from air, more precisely from oxygen in air. Because oxygen is required to participate in normal metabolism of a human body, in an oxygen-deficient environment, such as a plateau with thin air and oxygen partial pressure lower than that of a low altitude area, people can generate various oxygen-deficient symptoms, such as headache, dizziness, insomnia, nausea, chest distress, short breath, severe syncope or death. Research shows that the atmospheric pressure is reduced by 1mmHg (about 133Pa) every 12 m of the elevation of the altitude, and the oxygen partial pressure is reduced proportionally, for example, at the altitude of 4000 m, the atmospheric pressure is only about 56% of the zero altitude area, and the corresponding oxygen partial pressure is also only about 56% of the zero altitude area. If the oxygen concentration of the breathing air can be improved, so that the oxygen partial pressure is improved, the oxygen deficiency reaction can not occur even in the plateau, and according to the calculation of the oxygen partial pressure, the altitude is reduced by about 1000 meters when the oxygen concentration is improved by 3 percent points.
