Mercury strain gauge venous occlusion plethysmography is a non invasive exploration of the lower limb venous hemodynamic. Classically, venous distensibility (delta V/V %) is expressed in terms of time during venous inflow (venous occlusion) and venous outflow (after cuff deflation). The authors proposed to express the total flow Q of the limb (obtained by a differentiator of the electric signal of the strain gauge) in terms of the venous distensibility (delta V/V %) whatever recording a top each second. This new representation Q = f(delta V/V) permit a more acute visualisation of the initial part of the venous emptying: more differentiation between venous drainage and systolic arterial waves, acceleration then deceleration of the venous emptying, return of the venous wall to its initial position later than venous emptying, active venous constriction. Some parameters are proposed to described this curve and the values obtained in 50 patients without and 10 patients with deep venous thrombosis are reported.
汞应变计静脉阻塞体积描记法是一种对下肢静脉血流动力学的无创检测方法。传统上，静脉扩张性（ΔV/V%）是根据静脉流入（静脉阻塞）和静脉流出（袖带放气后）过程中的时间来表示的。作者提议根据静脉扩张性（ΔV/V%）来表示肢体的总血流量Q（通过应变计电信号的微分器获得），无论每秒记录一次峰值。这种新的表示形式Q = f(ΔV/V)能够更敏锐地观察到静脉排空的初始部分：静脉引流与收缩期动脉波之间的差异更大、静脉排空的加速然后减速、静脉壁恢复到初始位置的时间晚于静脉排空、静脉主动收缩。文中提出了一些参数来描述这条曲线，并报告了50例无深静脉血栓形成患者和10例有深静脉血栓形成患者所获得的值。
