Abstract
The system interacts with an apparatus for extracorporeal blood treatment, which is connected to the venous vascular system of a patient via an inflow line and an outflow line. Temperature influencing means for causing an initial local temperature deviation Tin the vicinity of a first point of the vascular system, as a result of which a traveling temperature change is introduced into the blood flow of the patient, a first temperature sensor for measuring the local temperature of the blood at a second point of the vascular system downstream of the first point, and a second temperature sensor for measuring the local temperature of the blood in the inflow line are provided. A computer system records the local blood temperature measured at the second point and at the inflow line, in each case as a function of time, and ascertains and evaluates a first and second thermodilution curve (TDK, TDK). A temperature deviation TEKBV, which is to be allocated to the extracorporeal blood treatment apparatus, is determined from the second thermodilution curve, and Tand TEKBV are correlated to one another for the purposes of determining the cardiovascular parameter.
