The measurement of the venous distensibility by straingauge plethysmography during a semi-continuous variation (3 mm Hg every 20 seconds) of the cuff pressure during its inflation from 0 to 100 mm Hg and its deflation allow to record the venous hysteresis and to determine accurately the venous pressure. The standardized and automatic (Periflow J.S.I.) new method is highly discriminative between controls and varicose patients.
在袖带压力从0至100毫米汞柱充气及放气过程中，通过应变计体积描记法以半连续变化（每20秒3毫米汞柱）测量静脉扩张性，可记录静脉滞后现象并准确测定静脉压。标准化且自动的（Periflow J.S.I.）新方法在对照组和静脉曲张患者之间具有高度鉴别性。
