N2 - To examine the effect of oscillated blood flow on hemodynamics, left ventricular assist circulation using oscillated blood flow were performed as chronic examination. Vibrating Flow Pump (VFP) was used for generating the high frequency oscillated blood flow. Blood flow rate of left ventricular assist circulation was approximately 11/min and its flow frequency was 25Hz. Systemic vascular resistance and arterial impedance were calculated to estimate the hemodynamics, both of during VFP driving and without VFP driving. From this study, it was suggested that normal sinus rhythm could be kept during left ventricular assist circulation using oscillated blood flow. Systemic vascular resistance was decreased during left ventricular assist circulation using oscillated blood flow. And arterial impedance may show that vascular reaction for pulse was normally kept during left ventricular assist circulation. Therefore, it was suggested that left ventricular assist circulation using oscillated blood flow may be able to use for awaked animal.
