WebFig. 1. During systole, the flow speed through the artery increases when compared with diastole. This increased speed causes the artery to expand, which in turn compresses the upper and lower blood nets. SPG is sensitive to the change in flow speed, and PPG is sensitive to the change in optical properties due to compression. - "Comparison of … WebResearch Article Vol. 11, No. 9/1 September 2024/Biomedical Optics Express 5353 pressorchallenge,theSPGwaveformmaintainedarobustsignal-to-noiseratio(SNR)under ...
