The staff of Dujiangyan Giant Panda National Park Protection Center found that a wild giant panda was looking for water in the snow on October 3-4, 65438/kloc-0, and the interface was very pleasing. The puddle that the wild giant panda is looking for in the photo is a small animal drinking point set up with human assistance. Wild giant pandas have also formed the natural concept of this drinking point. Although the puddle in winter is covered with ice and snow, the baby panda will still go to the drinking point to fry ice to find water to drink. After working in the plateau for a long time, I returned to my daily life in the plain area again, resulting in the plain? Unconformity reflex? , that is? ● Primary reaction? . At the pharmaceutical level, it is also often called? Toxic oxygen disease? .

As we all know, people who first go to the plateau will have repayment reactions such as increased hemoglobin concentration, difficulty breathing and rapid heartbeat. For a long time, the body has certain adaptability to the natural environment of hypoxia in plateau area. From the plateau to the plain, it also led to the change from the natural environment with hypoxia to the natural environment with normal oxygen. The integration of human physiology into plateau has become a thing of the past. Historical time daily task? After implementation, it will gradually ease or subside. This transformation is called. Break away? .

Like that? Deoxygenation? Reaction, such as fatigue, fatigue, always want to sleep, chest tightness, shortness of breath, syncope, diarrhea and other diseases may occur, just like being drunk. Because of the health status of some friends, the values of blood night, cardiopulmonary and other physiological indexes are abnormal, and will continue to decrease again after returning to the plain value, even less than the plain value. Some people who have settled in the plain for more than 2 years will continue to have adverse physiological needs such as decreased hemoglobin concentration, slow heartbeat, increased cardiac output, increased blood flow and reversal of rheumatic heart disease.

Avoid? Drink oxygen? The most effective way is to increase the metabolic time of the human body. It is clearly put forward that the connection between plateau area and plain area should be adopted. From shallow to deep? Preventive countermeasures; For example, descend 5000 meters to 3000 meters first, trim for a period of time before descending, and enter the high oxygen warehouse if necessary 1? Two treatments? Drink oxygen? Symptoms can be alleviated.
