Precautions:
1. Don't exercise or do aerobic exercise for three days before going to the plateau to reduce the oxygen consumption of the body.
2. Don't eat anti-hyperreflexia drugs indiscriminately. Some drugs contain sedatives, which have a good effect at that time, and are even more uncomfortable after the drug effect, resulting in dependence and bad for the body.
3. Don't take oxygen if you can't, and speed up your body's adaptation to the plateau. It's really hard to take oxygen. Go to the hospital to take medicine and take oxygen if necessary.
