Altitude of 3000 meters above the area known as the plateau region, at an average altitude of 4000 meters, which is characterized by low air pressure, oxygen partial pressure is also low, easily lead to the body of oxygen, such as the prevention of inappropriate measures, which can cause the plateau is not indication.
