血压测量的标准化对于筛查项目的实施至关重要，对于社区血压控制的多中心合作调查尤其如此。这一需求源于许多众所周知的血压测量变异性的来源，其中一些可归因于仪器和观察者的性能特征。近年来开发了许多仪器，目的是克服这种测量变化的某些方面。因此，国家心肺研究所高血压检测和随访项目协调中心（HDFP）承担了对其中几种设备的评估，以便为该项目选择最佳的血压测量方法。以汞柱血压计作为标准，汞柱血压计是大多数可用的血压流行病学数据的基础。在第一个实验中，基于希腊-拉丁方形设计，测试的五个自动化设备中没有一个比标准汞血压计更好，从每个设备的两个样本的多个读数的平均值来判断。在一系列成对读数中，除一个外，所有自动装置都显示与标准水银血压计的读数有明显偏差。还记录了对机器性能的定性观察，并指出几个设备存在严重的操作困难，不幸的是，包括在第二次实验中表现良好的设备。为了本计划的目的，所有测试的自动化设备都没有表现得足够好，不能推荐它们替代标准水银血压计。一种改良型的水银血压计，旨在减少观察者的偏差，被包括在这次评估中，确实比较好，并将与标准设备一起被项目使用。
Standardization of blood pressure measurements is critical for the implementation of screening programs, and especially so for a multicenter, collaborative investigation of community blood pressure control. This need arises from numerous well known sources of variability in blood pressure measurements, some of which are attributable to performance characteristics of instruments and observers. A number of instruments have been developed in recent years with the aim of overcoming certain aspects of this measurement variation. Consequently, the Coordinating Center of the National Heart and Lung Institute Hypertension Detection and Follow-up Program (HDFP) undertook to evaluate several of these devices in order to permit selection for this Program of optimal methods of blood pressure measurement. The mercury sphygmomanometer, which is the basis of most available epidemiologic data on blood pressure, was taken as the standard.In the first experiment, based upon a Graeco-Latin square design, none of the five automated devices tested compared favorably with the standard mercury sphygmomanometer, as judged by the mean values of multiple readings for each of the two specimens of each device. In a series of paired readings, all but one of the automated devices showed marked deviation from readings by the standard mercury sphygmomanometer. Qualitative observations on machine performance were also recorded and indicated serious operating difficulties with several devices—including, unfortunately, the device that had performed well in the second experiment.For the purposes of the Program, none of the automated devices tested performed adequately to recommend their substitution for the standard mercury sphygmomanometer. A modified type of mercury sphygmomanometer, designed to reduce observer bias, was included in this evaluation, did compare well, and will be used by the Program in conjunction with the standard device.
