WebThe results confirm that arterial stiffness occurs in young adults, and demonstrate that a difference of arterial stiffness exists between young male and female. This study … WebDec 30, 2024 · Wang et al. have divided the PPG area into two areas at the dicrotic notch and the ratio of the two areas can be used as an indicator of total peripheral resistance. Takazawa et al. [ 17 ] believed that the ratio of the amplitude between peak and dicrotic notches in PPG can be served to reflect the compliance of the elastic arteries.

Webpeaks from the PPG signal and takes care to eliminate the minor peaks due to dicrotic notches and noise by using the wave amplitudes in combination with a moving average technique. The difference between successive valley amplitude and peak amplitude (valley – peak difference (VPD)) gives the amplitudes of systolic and dicrotic waves.
