Automated blood pressure measurements are usually characterized by poor operational reliability and a considerable degree of complexity in performing the measurement. This paper introduces a new technique for the indirect measurement of the systolic and diastolic blood pressure of an individual. The technique is based upon a statistically consistent relationship between the amplitude of the pulsative pressure waveform at the systolic and diastolic points, and the amplitude of pulse signals detected when the artery is fully occluded. Clinical testing and statistical analysis techniques are used to derive appropriate numerical values for these relationship. The proposed procedure thus incorporates an adaptive measurement philosophy achieving minimum observer involvement and consequently high instrument accuracy. Overall measurement errors are maintained well within proposed standards for automated sphygmomanometers.
自动血压测量通常具有操作可靠性差以及测量过程相当复杂的特点。本文介绍了一种间接测量个体收缩压和舒张压的新技术。该技术基于收缩期和舒张期脉动压力波形的幅度与动脉完全闭塞时检测到的脉搏信号幅度之间的统计一致关系。使用临床测试和统计分析技术来推导这些关系的适当数值。因此，所提出的程序采用了一种自适应测量理念，实现了观察者的最少参与，从而提高了仪器的准确性。总体测量误差保持在自动血压计建议标准范围内。
