本文通过观察健康青年男性从平原到不同高海拔地区不同时间段的动脉血压变化,旨在探讨动脉血压变化与不同海拔发生AMS之间的关系,以评价动脉血压测量在AMS诊断中的作用。作者收集世居平原(海拔500m)、急进高原(海拔3 700m)第1、3、5、7天及进入更高海拔地区(海拔4 400m)第5天时人群的人口学资料,测量动脉血压[收缩压(SBP)、舒张压(DBP)、平均动脉压(MABP)等],并填写AMS流行病学观察表。另以平原健康青年男性作为对照组。以路易斯湖AMS计分系统(LLS)诊断AMS。分析上述各人群进入高原后的动脉血压变化及其与AMS的关系。结果由平原急进高原(海拔3 700m)第1天SBP、DBP、MABP均明显升高,习服 In this paper, by observing the changes of arterial blood pressure at different time intervals from plain to different high altitude in healthy young men, this study aimed to explore the relationship between arterial blood pressure changes and AMS at different altitudes to evaluate the role of arterial blood pressure measurement in the diagnosis of AMS. The authors collected demographic data on the first plains (500 m above sea level), on the first, third, fifth and seventh days on an advancing plateau (3 700 m above sea level) and on the fifth day into a higher altitude (4 400 m above sea level), and measured arterial blood pressure [ Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MABP), etc.] and fill in the AMS Epidemiological Watch. Another plain healthy young men as a control group. AMS was diagnosed using the Lake Louise AMS Scoring System (LLS). The changes of arterial blood pressure after entering the plateau and the relationship with AMS were analyzed. Results SBP, DBP and MABP were significantly increased on the first day of rapid plateau (3 700 m above sea level)
