Blood flow in the circulation is pulsatile. With each beat, the heart pumps energy into the blood. This energy is dissipated and stored. How the blood will dissipate and store energy is related to both the viscosity and elasticity of the blood. Red blood cells (erythrocytes) play a dominant role in blood viscoelasticity and its response to pulsatile flow. With oscillatory flow, the BioProfiler and Vilastic-3 can measure the viscosity that is related to energy dissipation and elasticity that is related to energy storage.
