Abstract

The invention relates to a method for determining a total fluid 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 dissipation loss (6) of the electric motor (5), d) ascertaining the total fluid volume flow (1) using the reference temperature (3), the motor temperature (4), and the thermal dissipation loss (6) of the electric motor (5).
