Validation of Photoplethysmography Device for the Measurement of Aortic Pulse Wave Velocity Against Carotid-Femoral Values From Piezoelectric Sensors

Existing techniques available for capturing reliable aortic pulse wave velocity measurements and estimating aortic stiffness are costly and require technical expertise. The purpose of this research is to investigate an oximeter device performance as a stand-alone aortic pulse wave velocity (PWV) measurement instrument. By validating this device and its measurements against the gold-standard method of carotid-femoral readings, we aim to demonstrate that the proposed method is an comparably effective in terms of the metrics (Mean difference, standard deviation, correlation, etc.) outlined by the Artery Society Guidelines.
