AB BackgroundThe direct Fick (dF) is the reference method for cardiac output (CO) measurements but Thermodilution (TD) is widely used in pre-capillary PH (pcPH) evaluation.AimTo compare, CO from dF (COFick), TD (COTD) and the Modelflow method applied to non-invasive pulse pressure profiles (COMF) .MethodsWe determined CO in pcPH patients at rest. COTD as the mean of 3 values, COMF of 100 beat-by-beat values, and COFick simultaneously.ResultsPatients characteristics are in the table. The figure shows (A) COMF against COFick (B) COMF - COFick against their mean (Bias: 0.7; Limits of agreement (LoA): -1.08/+2.48). (C) COTD against COFick . (D) COTD - COFick against their mean (Bias: -0.20; LoA: -2.55/+2.15).View this table:Characteristics of the study populationConclusionMF showed better correlation and precision than TD when compared to dF. Calibration with a reference method is needed to improve accuracy.
