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.

Carotid-femoral aortic pulse wave velocity will be compared against values collected from the oximeter system. The former is assessed by placing piezoelectric pressure sensors at three locations: the right common carotid artery, the right common femoral artery (groin), and the right superficial femoral artery (thigh). The oximeter will be secured on the right index finger. Simultaneous data collection will occur for both methods, with each trail lasting 60 seconds.
Aortic Pulse Wave Velocity
The speed at which a single pulse/heart beat propagates down the aorta.
Time frame: 6 measurements per subject, each lasting 60 seconds
