METHOD FOR DETERMINING A FLUID TOTAL VOLUME FLOW IN THE REGION OF AN IMPLANTED VASCULAR SUPPORT SYSTEM AND IMPLANTABLE VASCULAR SUPPORT SYSTEM

摘要

The invention relates to a method for determining a fluid total volume flow (1) in the region of an implanted vascular support system (2), comprising the following steps: a) determining a reference temperature (3) of the fluid; b) determining a motor temperature (4) of an electric motor (5) of the support system (2); c) determining the thermal power loss (6) of the electric motor (5); d) determining the fluid total volume flow (1) using the reference temperature (3), the motor temperature (4) and the thermal power loss (6) of the electric motor (5).
