本研究旨在验证示波式血压监测仪测量的血压值，并寻找可能的校准方法，如果存在差异。使用示波式血压监测仪(欧姆龙HBP-1300)和汞血压计(标准设备)来确定无创血压测量结果。在这项研究中，2%的参加流行病学调查的受试者被系统抽样。用组内相关系数评价测量信度，用配对t检验评价真实性，用线性回归进行校正。验证质量评估采用美国医疗器械促进会(AAMI)标准和英国高血压学会(BHS)协议，汞血压计(标准装置)和示波式血压监测仪(测试装置)均具有较高的可靠性。观察到不同设备之间的收缩压(SBP)有显著差异。用有效的线性回归模型对收缩压进行校正(B=0.803，常数=19.592，P
This study aims to validate blood pressure (BP) values measured by an oscillometric BP monitor and seek possible calibration methods if discrepancies exist.Noninvasive BP measurement outcomes were determined using an oscillometric BP monitor (Omron HBP-1300) versus a mercury sphygmomanometer (standard device). Two percent of subjects enrolled in an epidemiological investigation were systematically sampled in this study. Intraclass correlation coefficient (ICC) was used to evaluate measurement reliability, paired t-test was used to evaluate trueness, and linear regression was used for calibration. The Association for the Advancement of Medical Instrumentation (AAMI) standards and British Hypertension Society (BHS) protocols were used for validation quality assessment.Both mercury sphygmomanometer (standard device) and oscillometric BP monitor (test device) displayed high reliability. A significant difference in systolic blood pressure (SBP) was observed between devices. SBP calibration was achieved by using an effective linear regression model (B=0.803 and constant=19.592, P
