Abstract
Hypoventilation and heart failure model of swines were treated by the bi-ventricular assist device incorporated menbrane oxygenator. Roller pump was used for right ventricular assist, pulsatile blood pump for left ventricular assist device and polypropylene hollow fiber for membrane oxygenator. Using this device, hemodynamics were improved, ie, right atrial pressure was dropped significantly and arterial pressure, total cardiac output were rised significantly. And the datas of blood gas analysis were also improved, using this device. This new assisted circuration device was able to treat cardiac failure, maintain systemic circulation and also improve hypoxia and hypercapnea, and it seems to be very effective for the cases that have heart failure associated respiratory failure.
