Figure 5From: Accuracy and precision of end-expiratory lung-volume measurements by automated nitrogen washout/washin technique in patients with acute respiratory distress syndromeComparison according to Bland and Altman [21]of measurements of ΔPEEP-volume and ΔEELV. Bias between the two methods was 97 ± 255 ml with a 95% confidence interval for the limits of agreement (dashed lines) of -414 to 608 ml.Back to article page
