From: Comparison of bedside measurement of cardiac output with the thermodilution method and the Fick method in mechanically ventilated patients

Figure 3

Comparison of cardiac output determined using the metabolic (Fick) method (QT FICK) and cardiac output determined using the thermodilution method (QT THERM) according to (a) the Bland and Altman graphic method [28], and (b) the Passing and Bablok regression method [29]. Restricted to the patients in whom cardiac echography ruled out tricuspid regurgitation (14 patients, 40 pairs of measurements, after removal of one outlier). CI, confidence interval; SD, standard deviation.
