  1. Results are shown as median (interquartile). PLR, passive leg raising; VE, volume expansion; HR, heart rate; SAP, systolic arterial pressure; MAP, mean arterial pressure; DAP, diastolic arterial pressure; ABF, aortic blood flow; LVETc, left ventricular ejection time corrected for heart rate; ΔPP, respiratory variation of pulse pressure (see the text). ap < 0.05 PLR versus Base 1, bp < 0.05, VE 250 ml versus Base 2, cp < 0.05, VE 500 ml versus Base 2.
