The innovation concerns a heart pump and in particular a method for operating a VAD (ventricular assist device) heart pump (3), in which method a time-dependent pressure of the blood to be delivered is measured directly by means of at least one pressure sensor (8, 21) arranged on the pump inlet (4, 41) and/or on the pump outlet (5, 42). A temperature of the blood is additionally detected. By evaluating the measured pressure profiles and/or corresponding rates of change of the measured pressure, it is possible for delivery parameters of the pump (3), and also physiological values of the heart assisted by the pump, to be determined in a convenient and reliable manner. |
