N2 - A design criterion was established for the maximum pressure swing tolerated by the cam-driven motor of the Electric Ventricular Assist Device (EVAD) being developed at Penn State University. It was found that pump performance sharply decreases for pressure swings greater than 5.33 kPa (40 mmHg). A two-phase fluid volume compensation chamber was developed that met the above design goal. The chamber, coated with an enhanced boiling surface, showed a pressure swing as low as 3.88 kPa (29.14 mmHg) for a stroke volume of 92.2 ml at a beat rate of 100 beats per minute.
