摘要

Previous in vitro studies in tubes with different elasticity under pulsatile flow conditions have demonstrate that Doppler power would lead or lag flow velocity waveform in different stroke rates and hematocrit The quantitative results of vessel elasticity dependence on stroke rates and flow velocity are still uncertain To better understand this phenomenon the Doppler power from porcine whole blood and porcine red blood cell suspensions with different tubes under pulsatile flow conditions was measured Three parameters that may alter the Doppler power were discussed in this study: 1 the dependence on stroke rates 2 the effect of the vessel wall elasticity and 3 the influence of the various flow velocities In the present study the experimental results were obtained with a 10-MHz full digital FPGA-based pulsed wave (PW) Doppler flowmeter The results show that the Doppler power from porcine red blood cell suspensions did not vary obviously (
