Title
Double Headed Probe for Local Pulse Wave Velocity Estimation - A New Device for Hemodynamic Parameters Assessment.
Abstract
The present work proposes a new device for local pulse wave velocity (PWV), by using an innovative configuration of a double piezoelectric (PZ) sensor probe. PWV is assessed in one single location and involves the determination of time delay, between the signals acquired simultaneously by two PZs, 23 mm apart. The double probe (DP) is characterized in a dedicated test bench system, where two main studies were carried out. In the first one, the impulse response (IR) for each PZ sensor is determined and evaluated through the deconvolution method. In the second one, DP time resolution is estimated from a set of time delay algorithms and compared with the reference values, obtained through the signals of two pressure sensors. Results demonstrate the effectiveness of the inferred IRs in deconvolution purposes and the possibility of measure higher PWV values (approximate to 19m/s), through the DP, with an error less than 10%.
