Ability of esCCO to track changes in cardiac output† M. Biais, R. Berthezène, L. Petit, V. Cottenceau, F. Sztark British Journal of Anaesthesia Volume 115, Issue 3, Pages 403-410 (September 2015) DOI: 10.1093/bja/aev219 Copyright © 2015 The Author(s) Terms and Conditions

Fig 1 Bland-Altman plots between cardiac output obtained with transthoracic echocardiography and cardiac output obtained by using esCCO before and after therapeutic intervention (passive leg-raising, volume expansion, increase or decrease in norepinephrine dosage). The continuous lines show the mean difference (bias) and the dotted lines show the 95% limits of agreement (2sd).

Fig 2 Variations in cardiac output (DeltaCO) induced by passive leg-raising (PLR). (a) Bland-Altman plots between changes in cardiac output (obtained using transthoracic echocardiography and esCCO). The continuous lines show the mean difference (bias) and the dotted lines show the 95% limits of agreement (2sd). (b) Four-quadrant trend plots with central exclusion zone (10%) for assessing the ability of the esCCO to trend cardiac output data. (c) Polar plots used to show trending ability. The distance from the centre of the plot represents the mean change in cardiac output, the angle with the horizontal axis represents disagreement.

Fig 3 Variations in cardiac output (DeltaCO) induced by an increase (NE+) or a decrease (NE−) in norepinephrine dosage. (a) Bland-Altman plots between changes in cardiac output obtained using transthoracic echocardiography and esCCO. The continuous lines show the mean difference (bias) and the dotted lines show the 95% limits of agreement (two standard deviations). (b) Four-quadrant trend plots with central exclusion zone (10%) for assessing the ability of the esCCO to trend cardiac output data. (c) Polar plots used to show trending ability. The distance from the centre of the plot represents the mean change in cardiac output, the angle with the horizontal axis represents disagreement.
