高原反应即急性高原病(AcuteHigh Altitude Disease,AHAD),是人到达一定海拔高度后,身体为适应因海拔高度而造成的气压差、含氧量少、空气干燥等变化,而产生的自然生理反应,海拔高度一般达到2700米左右时,就会有高原反应。未经适应训练的人迅速进入3000米以上高原地区,由于大气压中氧分压降低,机体对低氧环境耐受性降低,难以适应而造成缺氧,由此引发一系列的高原不适应症。当然,除了高原缺氧的因素之外,还有恶劣天气如风、雨、雪、寒冷和强烈的
Acute high altitude sickness (Acute High Altitude Disease, AHAD), is a person to reach a certain altitude, the body to adapt to altitude differences caused by air pressure, oxygen content, air drying and other changes, and the resulting natural physiological response , Altitude generally reach 2700 meters, there will be altitude sickness. Unconverted people quickly entered the plateau area of more than 3,000 meters. Due to the decrease of partial pressure of oxygen in the atmosphere, the body is less able to tolerate the hypoxia environment and thus it is difficult to adapt to hypoxia. As a result, a series of altitude incompetence emerges. Of course, in addition to the high altitude hypoxia factors, there are bad weather such as wind, rain, snow, cold and strong
