Figure 2From: Comparison of bedside measurement of cardiac output with the thermodilution method and the Fick method in mechanically ventilated patientsPassing and Bablok regression of cardiac output determined using the metabolic (Fick) method (QT FICK) against cardiac output determined using the thermodilution method (QT THERM) [29] restricted to (a) QT THERM values <5 l/min and (b) QT THERM values >5 l/min (after removal of one outlier).
