Qinghai-Tibet railway opened to traffic more than a year ago, 1 / 3 of the passengers suffered varying degrees of altitude sickness, in addition to affecting the plateau tourism, coupled with the lack of altitude hypoxia majority of the passengers protection of basic knowledge, and some even lead Serious altitude sickness. Therefore, the forthcoming opening of the Qinghai-Tibet Railway two anniversary, invited the Chinese Academy of Engineering, the Ministry of Railways altitude physiology Wu Tien a team of experts compiled this article for our readers.
Qinghai-Tibet Plateau, high mountain clear water, the snow conditions Sphygmomanometer and customs, culture, attracting a growing number of visitors, especially the July 1, 2006 after the opening of the Qinghai-Tibet Railway Line, "in that distant place" is no longer distant. Beijing to Lhasa only 50 hours, a time, are fully booked train car, Xining and Lhasa, tourists like clouds, the plateau in her mother's mind Yong great satisfaction with the country and around the world friends. However, as the "roof of the world," the Qinghai-Tibet Plateau, the world is a special high-altitude hypoxia environment, whether by train across the Qinghai-Tibet Road, this day, or in the snow-covered plateau tourism resort, will be the impact of altitude hypoxia . How to ensure the health of the broad masses of tourists, to make it a "plateau health tourism", will be a plateau of a new medical challenges.
Qinghai-Tibet Railway is the most important feature, along the Sphygmomanometer main site at an altitude of 4,000 to 4,500 meters or about 60 percent, when the atmospheric pressure and atmospheric oxygen at sea level or about 40 percent, while site at an altitude of 4,600 to 5,000 M also accounted for about 40 percent, when the atmospheric pressure and atmospheric oxygen near the sea level, only 50 percent of the. Hypoxia human inhalation of such gases, resulting in the oxygen content in the blood dropped, called "hypoxia," that is, our habit of "hypoxia," This is the plateau of the key factors affecting the human body.
Generally speaking, more than 2,000 metres above sea level, the body began to hypoxia response, elevation 3,000 meters above, hypoxia physiological responses seen almost everyone, elevation 4,000 to 5,000 metres, hypoxia caused significant physiological responses, Some people will acute altitude sickness. Inevitably, the Qinghai-Tibet by train, 10 to 12 hour passenger to suffer a significant impact on the hypoxia. Therefore, in order to solve the highland anoxia on the train and guarantee the safety of passengers, the Ministry of Railways altitude physiology The group doing an in-depth study.
Travel before "instructions" body
The passengers, some people suffering from a disease or a sub-healthy state, but he does not know. When he entered the altitude hypoxia environment, the disease can be acute or rapidly deteriorating, and sometimes very dangerous, such as frequent angina attack, myocardial infarction, cerebrovascular accident, gastrointestinal hemorrhage, diabetic acidosis, and so on. Therefore, in preparing to enter the high altitude before, it should be done to the formal hospital a comprehensive physical examination, such as blood pressure, ECG, lung function, blood Sphygmomanometer biochemistry, and other items to be seized.
To prevent visitors from physical conditions are not suited altitude reaction, the Qinghai-Tibet train ticket window specifically for tourists, "passenger health registration card", you seriously truthfully fill out in order to train health room you really grasp the situation, including at any time and your family and units Links.
In addition, elderly people over the age of 60 cardiopulmonary function Sphygmomanometer will be to reduce or potentially elderly patients, we should pay special attention to medical examination before. Children under the age of two poor ability to adapt to, the proposed best not taken to the plateau tourism.
