摘　　要：目的采用美国医疗器械检测协会(AAMI)标准,对HEM-6000手腕式血压计的血压测量精确度进行临床验证研究。方法入选对象为18岁以上成年人,共91人。腕部测压结果与听诊法比较。每位受试者用2种方法同时各进行3次坐位血压测量,对91人的273对血压测量值用以下2种方法进行统计分析:(1)先计算出2种测压方法得到的血压测量值误差,再求得误差的平均值和标准偏差。(2)先计算出每位受试者用2种测压方法得到的血压平均值的差值,再求得该差值的平均值和标准偏差。结果根据方法1得到的收缩压(SBP)和舒张压(DBP)的测量误差分别为(0.5±7.1)mm Hg和(-1.6±6.1)mm Hg;根据方法2得到的结果分别(0.5±6.1)mm Hg和(-1.6±5.3)mm Hg。血压值的水平及手腕周长对测量误差无影响。结论HEM-6000手腕式血压计通过AAMI检验标准,可推荐患者用于家庭自我测压。Objective To determine the accuracy of blood pressure measurement by HEM-6000 automated wrist blood pressure monitor according to the Association for the advancement of medical instrumentation （AAMI） criteria. Methods Ninety-one participants 〉18 years of age were enrolled. The blood pressure measurements at the wrist were compared with the results obtained by auscultatory measurement on left upper arm. Both measurements were taken 3 times in each person. A total 273 measurements were obtained in 91 participants. The evaluation of the accuracy was assessed by 2 statistical methods. （1）The differences between the 2 devices for a given measurement. （2） The differences between the 2 devices for a given person. Results Method 1 showed the sample mean errors and standard deviation of errors were 0. 5±7.1 mm Hg for systolic blood pressure（SBP） and -1.6±6. 1 mm Hg for diastolic blood pressure（DBP）. Method 2 showed they were 0. 5±6. 1 mm Hg for SBP and - 1.6±5.3 mm Hg for DBP. Blood pressure level and the wrist circumferences had no influence on the measurement errors. Conclusion The HEM-6000 wrist blood pressure device apparently met the AAMI criteria and is valid for patient self-measurement.
