慢性高原病(CMS)是青藏高原最常见的高原病,以红细胞过度增多和肺动脉高压显著增高为临床特征,国际上统一应用“青海标准”作为诊断标准。海拔3000 m以上人群患病率约为5%,汉族移居人群的患病率是世居藏族的5倍,居住海拔过高、劳动过强、男性、汉族、吸烟和坐业劳动是主要危险因素。周边化学感受器颈动脉体对低氧通气反应钝化是造成显著低氧血症和红细胞过度增生的原发机制。某些中、藏药物有一定的致适应作用,但有效控制危险因素和提高人体习服-适应能力是防治的关键。
Chronic altitude sickness (CMS) is the most common high altitude sickness in the Tibetan Plateau. With clinical manifestations of erythrocytosis and pulmonary hypertension, the “Qinghai standard” is the uniform standard in the world. The prevalence rate of people above 3000 m above sea level is about 5%. The prevalence rate of Han immigrants is 5 times that of the native Tibetans. Living in high altitude and overworking, men, Han nationality, smoking and work-taking are the main risk factors . Peripheral chemoreceptor carotid body hypoxia ventilation passivation is caused by significant hypoxemia and erythroid hyperplasia primary mechanism. In some cases, Tibetan medicine has a certain adaptation effect, but effectively controlling risk factors and improving human body accustomed - adaptive ability is the key to prevention and treatment.
