平原人群快速进人高原,由于机体对缺氧的耐力较差,高原低氧引起机体组织器官正常生理功能障碍,发生急性高原反应(AMS),在青藏高原海拔4000-4700m地区发生率达59%~65%,在喀喇昆仑山海拔5000~5200m地区高达91%,导致机体发生头痛、恶心、呕吐等临床症候群,若治疗不及时往往继发高原肺水肿、高原脑水肿,甚至危及生命;另一方面,久居高原的习服人群进入平原时,机体重新适应平原环境,会出现高原脱习服症状,如疲倦、无力、嗜睡、头晕
Plains quickly into the plateau, the body due to poor endurance of hypoxia, plateau hypoxia caused by normal physiological and functional disorders of body tissues and organs, the occurrence of acute altitude sickness (AMS), in the Tibetan Plateau at an altitude of 4000-4700m area 59% ~ 65%, up to 91% in the Karakorum Mountains from 5000 to 5200m above sea level, leading to headache, nausea, vomiting and other clinical syndromes in the body. If the treatment is not timely, high altitude pulmonary edema, high altitude brain edema and even life-threatening may occur; On the one hand, people living in plateau habitat into the plains, the body re-adapt to the plains environment, there will be symptoms of altitude sickness, such as fatigue, weakness, drowsiness, dizziness
