Arterial and central venous pressures, Pulse Pressure Variation and Stroke Volume Variation. Boxplots with median, IQR and range; #: P < 0.01; *: P < 0.05; broken-lined brackets represent differences between the individual fluid states for VCV only; solid-lined brackets represent differences for both ventilation regimes.SAP, systolic arterial pressure; MAP, mean arterial pressure; DAP, diastolic arterial pressure; PPV, pulse pressure variation; SVV, stroke volume variation; CVP, central venous pressure; BL, baseline; Hypo, hypovolaemia; Res I, resuscitation stage I; Res II, resuscitation stage II.
