Photoplethysmogram variability
text:
The photoplethysmogram (PPG) measurement made at a peripheral site, such as the finger, ear or forehead represents the volume of blood in the vessel at the site of measurement. The PPG signal consists of pulses that reflect the change in vascular blood volume with each cardiac beat. Beat-to-beat fluctuations, known as photoplethysmogram variability (PPGV) are found in the signal baseline and amplitude which reflects various physiological influences such as respiration and regulation of vascular
