Photoplethysmography is a noninvasive method for fast diagnosis of blood flow disturbances in the venous system of the lower limbs. It is suitable for discriminating normal from pathological venous findings. The technique has been evaluated in three groups of subjects with edema of the lower extremities. The value of this screening method in the diagnosis of vascular disorders and edema of the lower limbs is discussed. Venous occlusion plethysmography is used for discriminatory and quantitative evaluation of venous function. The diagnostic value of strain gauge plethysmography was assessed in three groups of subjects. Measured parameters were venous capacity and venous outflow. Digital photoplethysmography is suitable for the discrimination of venous edema of the lower limbs from edema caused by other factors, and digital "strain gauge" plethysmography for the discrimination of edema of the lower limbs, caused by phlebothrombosis from edema caused by other factors.
光电容积描记法是一种用于快速诊断下肢静脉系统血流紊乱的非侵入性方法。它适用于区分正常与病理性静脉表现。该技术已在三组下肢水肿患者中进行了评估。讨论了这种筛查方法在诊断下肢血管疾病和水肿中的价值。静脉阻塞容积描记法用于静脉功能的鉴别和定量评估。在三组受试者中评估了应变片容积描记法的诊断价值。测量参数为静脉容量和静脉流出量。数字光电容积描记法适用于区分下肢静脉水肿与其他因素引起的水肿，而数字“应变片”容积描记法适用于区分下肢静脉血栓形成引起的水肿与其他因素引起的水肿。
