In this paper, the value of venous occlusion plethysmography in the differentiation between normal and abnormal is discussed. Data are obtained with an ECG triggered plethysmograph allowing an automatic and also a fast recording of the different parameters of the reactive hyperemia. A group of 74 proven "normal" limbs and of 93 proven "abnormal" limbs was studied. No difference in resting blood flow was seen; however, several parameters derived from reactive hyperemia were significantly different; curves obtained after arrest of the circulation during 3 minutes yielded the best results. Discriminant analysis showed that peak blood flow was the best individual performing parameter; using four variables of the reactive hyperemia curve, an overall performance of 84.9% was obtained with specificity of 93% and sensitivity of 76%. The place of plethysmography in the definition of vascular changes is discussed.
本文讨论了静脉阻塞体积描记法在区分正常与异常情况方面的价值。数据是通过心电图触发的体积描记器获得的，该仪器能够自动且快速地记录反应性充血的不同参数。研究了一组74条经证实为“正常”的肢体和93条经证实为“异常”的肢体。静息血流量未见差异；然而，从反应性充血得出的几个参数有显著差异；在循环阻断3分钟后获得的曲线产生了最佳结果。判别分析表明，峰值血流量是表现最佳的个体参数；使用反应性充血曲线的四个变量，总体表现为84.9%，特异性为93%，敏感性为76%。本文还讨论了体积描记法在血管变化定义中的地位。
