  1. CO-FloTrac = cardiac output obtained with Vigileo™ device; CO-TTE = cardiac output obtained with transthoracic echocardiography; CVP = central venous pressure; HR = heart rate; MAP = mean arterial pressure; PLR = passive leg raising; SV-Flotrac = stroke volume obtained with Vigileo™ device; SVR = systemic vascular resistance; SV-TTE = stroke volume obtained with transthoracic echocardiography; VE = volume expansion; VTIAo = velocity-time integral of aortic blood flow. P1 = during PLR values vs baseline values, P2 = after VE values vs before VE values.
