Type: Lecture

Speech: English

The purpose of this study was to determine potential of remote photoplethysmography for skin perfusion monitoring using 540 nm narrowband and 530 nm broadband illuminations. The alterations of cutaneous circulation were produced by topical skin heating protocol. Two setups were utilized: 1) white LED light source, video camera and narrowband optical filter (CWL=540nm), and 2) 530 nm LED light source and same video camera. Results demonstrate that typical heating test response curve- comprising first peak, nadir and plato phase were significantly different in narrowband and broadband illumination, the largest difference was related to nadir and first peak. It has was concluded that selection of optimal light source parameters is crucially important for registering of physiological responses using rPPG, and therefore require more extensive studies.
