The objective of this study was to compare blood pressure (BP) measured by the sphygmooscillographic method with that measured by the direct and auscultatory methods.
In 15 adult patients undergoing cardiac surgery, blood pressure was measured by the sphygmooscillographic and direct methods simultaneously on the same upper extremity. In another group of 86 children and 11 adults, blood pressure was measured by the sphygmooscillographic and auscultatory methods simultaneously, with one cuff. For the sphygmooscillographic measurement, we used sphygmomanometer-S, which measures blood pressure on the basis of the amplitude height (oscillometric) and the morphology (sphygmographic) of pulse waves recorded by a transducer placed in the cuff.
The systolic and diastolic blood pressure measured by the sphygmooscillographic method were both 2 mm Hg higher than those from the direct method; the mean blood pressure was 0.6 mm Hg higher. These differences were not significant. Compared with the auscultatory method, sphygmooscillographic systolic values were higher by 7 mm Hg, while diastolic values were lower by 9 mm Hg. These differences were significant.
Blood pressure measurements obtained by the sphygmooscillographic method correlate well with the direct method for measuring blood pressure in children and adults; but, they do not correlate well with the auscultatory method.
本研究的目的是比较采用脉搏示波法测量的血压与采用直接法和听诊法测量的血压。
在15例接受心脏手术的成年患者中，在同一上肢同时采用脉搏示波法和直接法测量血压。在另一组86名儿童和11名成人中，使用一个袖带同时采用脉搏示波法和听诊法测量血压。对于脉搏示波法测量，我们使用了血压计-S，它基于放置在袖带中的传感器记录的脉搏波的振幅高度（示波法）和形态（脉搏描记法）来测量血压。
采用脉搏示波法测量的收缩压和舒张压均比直接法测量的值高2 mmHg；平均血压高0.6 mmHg。这些差异不显著。与听诊法相比，脉搏示波法的收缩压值高7 mmHg，而舒张压值低9 mmHg。这些差异显著。
采用脉搏示波法测量的血压与儿童和成人测量血压的直接法相关性良好；但与听诊法相关性不佳。
