Comparison of two versions of the Vigileo-FloTrac™ system (1.03 and 1.07) for stroke volume estimation: a multicentre, blinded comparison with oesophageal Doppler measurements R.

Fig 1 Box plots showing the effect of two consecutive fluid challenges (250 ml of saline each) on heart rate (a), mean arterial pressure (MAP, b), and SV measured using the oesophageal Doppler (c). *P<0.05 vs baseline; $P<0.05 vs 250 ml. The error bars indicate 10th and 90th percentiles, and the open circles indicate values below or beyond the latter limits, respectively.

Fig 2 Graphs representing agreement between SV values obtained using oesophageal Doppler (SVOD) and Vigileo™ (SVVI) with version 1.03 (207 paired cardiac output values, 29 patients). Bias value was 1 ml and limits of agreement were ± 75 ml. British Journal of Anaesthesia , DOI: ( /bja/aep020) Copyright © 2009 British Journal of Anaesthesia Terms and Conditions

Fig 3 Graphs representing agreement between SV values obtained using oesophageal Doppler (SVOD) and Vigileo™ (SVVI) with version 1.07 (240 paired cardiac output values, 31 patients). Bias value was 4 ml and limits of agreement were ± 41 ml. British Journal of Anaesthesia , DOI: ( /bja/aep020) Copyright © 2009 British Journal of Anaesthesia Terms and Conditions

Fig 4 Graphs representing the correlation (a) and agreement (b) between the change in SV between two readings measured using oesophageal Doppler (ΔSVOD) and Vigileo™ (ΔSVVI) with version 1.03 (134 paired variations in SV, 29 patients). Bias value was 0 ml, and limits of agreement were ± 47 ml. The dotted lines in (a) delimit four quadrants: upper left and lower right quadrants correspond to data for which the two techniques yielded results of opposite sign.

Fig 5 Graphs representing correlation (a) and agreement (b) between the change in SV between two readings measured using oesophageal Doppler (ΔSVOD) and Vigileo™ (ΔSVVI) with version 1.07 (165 paired variations in SV, 31 patients). Bias value was 0 ml and limits of agreement were ± 35 ml. The dotted lines in (a) delimit four quadrants: upper left and lower right quadrants correspond to data for which the two techniques yielded results of opposite sign.
