Imaging Photoplethysmography for Monitoring of Vascular Response to Local Heating

In this study, the response of skin blood flow to lo-cal heating of subject's forearm was assessed by imaging photo-plethysmography. The proposed system is featured by accurate control of the parameters affecting the endothelium during pro-longed measurements. It is shown that this method reliably re-flects the function of the mechanisms of regulation of peripheral vascular resistance, which is of great prognostic value for the de-tection of cardiovascular diseases.
