Abstract

The invention relates to indicator dilution measurements of a central volume (V1) with a first site of injection (S1) upstream of the central volume (V1) a second site of detection (S2) of the diluted indicator downstream of the central volume (V1), wherein a first additional volume (V2) is defined between the first site (S1) and the central volume (V1) and a first additional branch (B2) is defined between the first site (S1) and the central volume (V1) and wherein a second additional volume (V3) is defined between the central volume (V1) and the second site (S2) and a second additional branch (B3) is defined between the central volume (V1) and the second site (S2) wherein a result of central volumetric parameters are corrected for the first and second additional volumes (V2, V3) and/or for the first and second additional branches (B2, B3).
