Abstract
Methods and systems are provided for determining an outlet pressure prevailing at an outlet of a heart assist system. An inlet pressure which prevails at an inlet of the heart assist system may be determined. A pressure difference between the inlet and the outlet of the heart assist system may be determined. The outlet pressure may be determined from the inlet pressure and the pressure difference.
Claims13
A heart assist system comprising:
- a pump for assistance of a heart;
- a cannula which is connectable to the pump, wherein the pump comprises a pump inlet and a pump outlet, and the cannula comprises a cannula inlet and a cannula outlet;
- a pressure detection system configured to detect a pressure at the pump inlet, which represents a ventricle pressure of a ventricle of the heart, and a pump pressure difference between the pump inlet and the pump outlet;
- and
- a control unit configured to estimate a cannula pressure difference between the cannula inlet and the cannula outlet, which represents a pressure difference along a bypass running between the ventricle and an aorta of the heart, and the control unit is configured to determine an aortic pressure from the pressure at the pump inlet representing the ventricle pressure and from the cannula pressure difference.
