1. What is the purpose of oxygen in the plateau?


For those who have recently entered the plateau, oxygen is taken to prevent serious altitude sickness complications such as high altitude cerebral edema and pulmonary edema.


  2. Why is the plateau lacking oxygen?


The reason why the plateau area is deprived of oxygen is because the plateau has low air pressure and low oxygen partial pressure, rather than low oxygen concentration. The atmospheric pressure in Lhasa is about 0.63 times that of the plain, so the partial pressure of oxygen absorbed in the plain is 159 mmHg (760 mmHg × 21%), and the partial pressure of oxygen sucked in Lhasa is about 101 mmHg (159 × 0.63).
