论文摘要
在这项研究中，提出了使用光摄像学原型的血管舒张定量方法，该方法与绿光结合使用，该原型进行了近红外光谱。一种抑制运动伪影并由眼镜固定在耳朵背面的结构，可以使总血红蛋白和脉搏波振幅的相对浓度变化在运动过程中测量，而在不存在风影响面部的情况下。我们建立了一个微循环的Windkessel模型，其中包括从深度方向上的血流变化估计的动静脉吻合，这些变化是使用三个波长的光线获得的，并在计算机上重现了血管敏感性。模型预测的值与测量值非常吻合。提取的血管症可用于理解中枢神经系统的自主控制。
In this study, a vasomotion quantification method using a photoplethysmography prototype, which performs near-infrared spectroscopy in combination with green light, is proposed. A structure that suppresses the motion artifact and that is held by the eyeglasses on the back of the ear enables the relative concentration changes of total hemoglobin and pulse wave amplitude to be measured during exercise with and without the presence of wind impacting the face. We established a microcirculatory windkessel model including arteriovenous anastomoses estimated from the blood flow changes in the depth direction that were acquired using three wavelengths of light and reproduced the vasomotion on a computer. The values predicted by the model were in good agreement with the measured values. The extracted vasomotion can be used to understand autonomic control by the central nervous system.
