WebAbstract A Windkessel model has been constructed with the aim of investigating the respiratory-volume dependence of the photoplethysmographic (PPG) signal. Experimental studies show a correlation between respiratory volume and the peak-to-peak value of the respiratory-induced intensity variations (RIIV) in the PPG signal. WebFig. 2. The experimental setup used two cameras and two light sources for imaging. The coherent NIR source remained constant, while the green source was switched between a coherent and incoherent source for PPG and SPG measurements. - "Comparison of speckleplethysmographic (SPG) and photoplethysmographic (PPG) imaging by Monte …
