Blood Pressure Estimation by Photoplethysmogram Decomposition into Hyperbolic Secant Waves

open access: yesApplied Sciences, 2022
Photoplethysmographic (PPG) pulses contain information about cardiovascular parameters. In particular, blood pressure can be estimated using PPG pulse decomposition analysis, which assumes that a PPG pulse is composed of the original heart ejection blood

Hemodynamic Data Analysis and Site of Measurement in Children and Adolescents

open access: yesArtery Research, 2020
Pulse wave velocity is a method of functional vascular evaluation. The gold standard is the carotid-femoral pulse wave velocity measurement. However, the software allows measurement among radial, carotid and femoral artery.
