In 35 patients with healthy vessels, 52 patients with vasospasm and 42 patients with stenoses or obliteration of the finger arteries with the help of the Parks-ultrasound-Doppler device model 806-A and a finger cuff of the size of 3.5 X 5 cm the systolic pressure of the finger arteries was measured before and after the administration of glycerol trinitrate. Since in test persons with healthy vessels no significant differences of the radial and ulnar volar finger artery, of the single fingers of one hand or in the comparison of the sides of the two hands was found, a concentration could be done. The relative and absolute increase of the pressure of the finger artery under glycerol trinitrate was most conspicuous in patients with vasospasm. No essential changes, as we expected, occurred in patients with organic disturbances of the arterial blood supply. Under variation of the lower limits of the norm of the pressure of the finger arteries the high values of the sensitivity, specificity and efficiency which are characteristic for the ultrasound-Doppler pressure measurement, lying over 0.90 particularly after pharmacologic vasodilation.
借助型号为806 - A的帕克斯超声多普勒设备和一个尺寸为3.5×5厘米的手指袖带，对35名血管健康的患者、52名血管痉挛患者以及42名手指动脉狭窄或闭塞的患者在使用硝酸甘油前后测量手指动脉的收缩压。由于在血管健康的测试者中，未发现桡侧和尺侧掌侧手指动脉、一只手的单个手指之间或双手两侧比较存在显著差异，因此可以进行合并。硝酸甘油作用下手指动脉压力的相对和绝对增加在血管痉挛患者中最为明显。正如我们所预期的，动脉血液供应存在器质性障碍的患者未发生实质性变化。在手指动脉压力正常下限变化的情况下，超声多普勒压力测量具有高敏感性、特异性和效率值，特别是在药物性血管扩张后，这些值超过0.90。
