Accuracy of pulse pressure variation to predict fluid responsiveness in subgroups of patients stratified by the different degrees of inspiratory effort. A: Comparison of pulse pressure variations between responders and non-responders in patients with P0.1 ≥ 1.5 cmH2O; B: Comparison of pulse pressure variation between responders and non-responders in patients with P0.1 < 1.5 cmH2O; C: Comparison of pulse pressure variation performance between patients with P0.1 < 1.5 cmH2O and patients with P0.1 ≥ 1.5 cmH2O; D: Comparison of pulse pressure variation between responders and non-responders in patients with ΔPocc ≥ − 9.8 cmH2O; E: Comparison of pulse pressure variation between responders and non-responders in patients with ΔPocc < − 9.8 cmH2O; F: Comparison of pulse pressure variation performance between patients with ΔPocc ≥ − 9.8 cmH2O and patients with ΔPocc < − 9.8 cmH2O. P0.1 Airway occlusion pressure, PPV pulse pressure variation, ΔPocc Airway pressure swing during a whole breath occlusion
