Fig. 4From: Blood volume in patients likely to be preload responsive: a post hoc analysis of a randomized controlled trialChange in pulse pressure (ΔPP) following a passive leg raising test in relation to blood volume, in patients included due to systolic BP < 100 or MAP < 65 mmHg. No significant correlation could be found (r = − 0.082 (95% CI − 0.598–0.483) p = 0.78, Spearman correlation coefficient). Dotted lines illustrate limits of euvolemia [13]Back to article page
