摘要

光容积脉搏波(PPG)是一种非侵入性的光学技术，用于测量器官或身体部位内的血量变化。在本研究中，使用PPG原型仪器测量了25人(38条腿)的慢性静脉功能不全(CVI)。将PPG评价结果与多普勒超声结果进行比较，多普勒超声是诊断CVI的金标准。计算PPG原型仪的灵敏度为82%，特异度为81%。

Evaluation of chronic venous insufficiency with PPG prototype instrument

Photoplethysmography (PPG) is a non-invasive optical technique for measurement of blood volume changes inside an organ or body part. In presented study, a chronic venous insufficiency (CVI) of 25 individuals (38 legs) was measured using PPG prototype instruments. The results of PPG evaluation were compared to results of Doppler ultrasound, which is the gold standard for diagnosis of CVI. The sensitivity and specificity of PPG prototype instrument in amount of 82% and 81%, respectively was calculated.
