Climbers at Everest Base Camp can buy oxygen. However, due to the limitation of carrying and storing in high altitude environment and the possibility of reducing the physical fitness and endurance of climbers, it is suggested that climbers should minimize their dependence on oxygen and improve their altitude adaptability through adaptive training.

It is very important to adapt to the plateau environment when climbing Mount Everest. Climbers usually need to go through weeks or even months of adaptation, including intensive training at low altitude and camping adaptation at high altitude. This adaptation process helps the body gradually adapt to the anoxic environment, thus reducing the demand for oxygen.

However, although oxygen can be purchased at Everest Base Camp, there are still many challenges and risks in the process of climbing. Climbers need to face extreme weather conditions, high-intensity exercise, steep climbing routes and high uncertainty. Therefore, before climbing Everest, climbers need to make full preparations and training to ensure that they have enough skills, physical quality and psychological quality to cope with possible problems and difficulties.

In short, Everest Base Camp provides oxygen purchase service, but climbers should try to reduce their dependence on oxygen and improve their altitude adaptability through adaptation training. Before climbing Mount Everest, you should make full preparations and training to reduce the risks and difficulties you may face.
