为了无创准确测量桡动脉瞬时血压（BP），通过与同时测量9名健康受试者的直接（有创）桡动脉压的比较，评估了基于容量补偿原理的装置的性能。收缩压（SBP）和舒张压（DBP）的偏差和精度分别来自本系统和直接方法的Bland-Altman图数据，在收缩压和舒张压的广泛范围内，平均分别为-0.5 plusmn 2.1 mmHg和0.6 plusmn 1.8 mmHg。这些结果清楚地表明，使用该系统，可以无创地测量瞬时桡动脉压力，精度高。
For the noninvasive and accurate measurement of instantaneous blood pressure (BP) in the radial artery, the performance of a device based on the principle of volume-compensation was assessed by comparison with simultaneous measurement of direct (invasive) radial artery pressure in nine healthy subjects. Bias and precision of systolic BP (SBP) and diastolic BP (DBP) derived from Bland-Altman plots of data from the present system and the direct method averaged -0.5 plusmn 2.1 mmHg and 0.6 plusmn 1.8 mmHg respectively, over a wide range of SBP and DBP. These results clearly indicate that, using this system, instantaneous radial artery pressure can be measured noninvasively with high accuracy.
