This study was designed to determine which method of measuring the brachial systolic blood pressure is most accurate when determining the ankle/brachial index (ABI). The accuracy of the stethoscope diaphragm was compared with the accuracy of the stethoscope bell and Doppler methods in measuring the brachial systolic pressure. These pressures were used in the calculation of the ABI, and then the ABI was compared by method and time since surgery. The sample consisted of 31 subjects who had peripheral arterial bypass surgery. The findings of this study indicate that there is no significant difference in the ABI when the brachial systolic blood pressure is measured by any of the three methods. A difference was found between the right-arm and left-arm brachial systolic pressures in many of the patients, and this would make a difference in the calculation of the ABI.
本研究旨在确定在测定踝臂指数（ABI）时，哪种测量肱动脉收缩压的方法最为准确。将听诊器膜型体件测量肱动脉收缩压的准确性与听诊器钟型体件及多普勒方法的准确性进行了比较。这些压力用于计算ABI，然后按测量方法和术后时间对ABI进行比较。样本包括31例行外周动脉搭桥手术的受试者。本研究结果表明，采用这三种方法中的任何一种测量肱动脉收缩压时，ABI均无显著差异。许多患者的右臂和左臂肱动脉收缩压存在差异，这会对ABI的计算产生影响。
