Abstract : An initial engineering analysis was made of the Army Artificial Heart Pump, Model O. The analysis demonstrates that the pump's output varies directly with propelling and filling pressures and inversely with circuit resistances in a manner similar to that of the human heart. The systolic pressure amplitude and pulse duration of the pump's output pulses can be varied within fairly broad limits. It is determined that the heart pump, using 0.020-in. thick, 85-durometer, polyvinylchloride ventricles can satisfy the design requirements for human perfusion, although pulse rates are low at high loads. Ventricles of slightly greater stiffness are required to match more exactly cardiovascular characteristics. For animal perfusions, ventricles of much greater stiffness or perhaps a different design are required. The functional capabilities of the pump apart from the ventricle appear to be satisfactory.
