The invention relates to a method for determining a fluid volume flow () through an implanted vascular support system (), comprising the following steps: a) determining a fluid temperature parameter in the region of a cannula () of the support system (), b) operating a heating element () which can bring about a change in a fluid temperature in the cannula (), c) determining the fluid volume flow () using at least the fluid temperature parameter or the change thereof and at least one heating element operating parameter or the change thereof. The invention also relates to a vascular support system.

The invention relates to a method for determining a total fluid volume flow () in the region of an implanted vascular support system (), comprising the following steps: a) determining a reference temperature () of the fluid, b) determining a motor temperature () of an electric motor () of the support system (), c) determining the thermal dissipation loss () of the electric motor (), d) ascertaining the total fluid volume flow () using the reference temperature (), the motor temperature (), and the thermal dissipation loss () of the electric motor ().

Systems and methods for determining a total blood volume flow in a cardiac support system and vascular support system

The invention relates to a method for detecting a state of wear of a cardiac support system. The method comprises a read-in step and a determination step. During the read-in step, a sensor signal () representing an operating state of the cardiac support system is read in. During the determination step, a wear signal () is determined using the sensor signal () and a comparison rule (). The wear signal () represents the wear condition.
