In indirect measurements of the blood pressure with the help of the ultrasound-Doppler-method important influence factors and sources of errors are to be taken into consideration. In order to estimate the importance of restricted vascular compressibility, changed tissue conditions and different position of the body, pressure measurements in patients with arterial obstructive disease and in test persons with healthy vessels were performed. The mediasclerosis leads to an extensive rigidity of the arterial wall so that falsely high measuring values could be established which were lying significantly above the intravasal pressure. For examination in the femoral region of a cuff of the standard breadth in relation to the volume of the extremity is too narrow to guarantee a lossless transmission of the pressure on the artery. After passive change of the position also in the poststenotic region significant changes of the pressure can be proved. As is shown by the results the desired diagnostic evidence with the help of the Doppler pressure is to be got only in such a case, when relevant influence factors are considered and the measurement is performed under standardized conditions.
在用超声多普勒法间接测量血压时，必须考虑重要的影响因素和误差来源。为了评估血管可压缩性受限、组织状况改变和身体不同位置的重要性，对患有动脉阻塞性疾病的患者和血管健康的测试人员进行了压力测量。中膜硬化导致动脉壁广泛僵硬，从而可能得出明显高于血管内压力的错误高测量值。在股骨区域进行检查时，相对于肢体体积而言，标准宽度的袖带太窄，无法保证压力无损传递到动脉上。被动改变体位后，在狭窄后区域也可证明压力有显著变化。结果表明，只有在考虑相关影响因素并在标准化条件下进行测量的情况下，才能借助多普勒压力获得所需的诊断证据。
