根据他的观察，提交人得出结论，正常情况下被压迫的动脉不会发出任何声音。利用这种情况，作者提出了一种听诊方法来测量血压在人类。Riva-Rocci袖带应放置在手臂的中间三分之一处;袖带中的压力迅速增加，直至完全阻塞远端血液循环。此后，让袖带内的压力降低，应使用儿童听诊器听诊压迫下方的动脉。手术开始时，听不到任何声音。当水银柱下降到某一点时，首先会出现一个短促的声音，这表明血液在袖带下通过。因此，当声音出现时的压力水平可以被视为最大血压。袖带压力的进一步降低伴随着动脉上的压迫性杂音，随后再次转化为明确的声音（第二个声音）。最后，所有的声音都消失了。这表示脉搏波的自由运动;换句话说，在这一点上，最低血压变得高于袖带压力。因此，此时的汞读数可以作为最低血压。动物实验得到了肯定的结果。第一个声音出现早于远端脉搏（10-12 mmHg），对于桡动脉上的后者触诊，需要更强的脉搏波。
On the basis of his observations, the author came to a conclusion that a compressed artery in normal conditions does not produce any sounds. Using this circumstance, the author proposes an auscultatory method to measure blood pressure in humans. The Riva-Rocci cuff should be posed in the middle third of the arm; the pressure in the cuff is rapidly increased up to complete obstruction of the distal blood circulation. Thereafter, letting the pressure in the cuff decrease, the artery just below the compression should be auscultated with a child stethoscope. At the beginning of the procedure, no sound can be heard. After the mercury column drops to a certain point, first a short sound appears, which indicates the passing of the blood under the cuff. Consequently, the level of the pressure when the sounds appear can be taken as the maximal blood pressure. A further decrease in cuff pressure is accompanied by compression murmurs on the artery, which later are again transformed into definite sounds (second ones). Finally, all sounds disappear. This indicates the free movement of the pulse wave; in other words, at this point, the minimal blood pressure becomes higher than the cuff pressure. Thus, the mercury readings at this moment can be taken as the minimal blood pressure. The animal experiments gave confirmative results. The first sound appears earlier than the distal pulse (10–12 mmHg), for the palpation of the latter on the arteria radialis a stronger pulse wave is required.
