Abstract

The multi photodiode array (MPA) is a novel transmission photoplethysmography sensor to measure pulse wave velocity (PWV) in the finger. To validate the MPA a setup was built to generate a red laser dot traveling over the MPA with known and constant scanning velocities. These scanning velocities were chosen to include speeds at least twice as high as those found in the normal range of PWV in healthy populations, and were set at 12.9, 25.8, 36.0 or 46.7 m/s. The aim of this study was to verify the functionality of the MPA: performing local non invasive PWV measurements. To illustrate the applicability of the MPA in clinical practice, an in vivo pilot study was conducted using the flow mediated dilation technique. The in vitro accuracy of the MPA was ± 0.2%, 0.3%, 0.5% and 0.6% at the applied scanning velocities. The MPA can measure PWVs with a maximum deviation of 3.0%. The in vivo pilot study showed a PWV before the flow mediated dilation of 1.1 ± 0.2 m/s. These results suggest that this novel MPA can reliably and accurately measure PWV within clinically relevant ranges and even well beyond.
