Zusammenfassung:A method and apparatus is provided for determining a stroke volume (SV) of an individual, comprising the steps of: providing a first pulse contour stroke volume based on one or more characteristics of a measured arterial blood pressure waveform or providing a conventionally derived pulse contour stroke volume, determining at least one perfusion parameter descriptive for the perfusion through the fat free mass and the adipose mass of a body of the individual, and/or determining at least one fluid responsiveness parameter function depending on a fluid responsiveness parameter descriptive for a heart-lung interaction of the individual, and adjusting the first pulse contour stroke volume or the conventionally derived pulse contour stroke volume based on at the least one of the perfusion parameter and/or the fluid responsiveness parameter function to provide a second pulse contour stroke volume.
