Open Access Abstract Introduction Passive leg raising PLR is a simple reversible maneuver that mimics rapid fluid loading and increases cardiac preload. The effects of this endogenous volume expansion on stroke volume enable the testing of fluid responsiveness with accuracy in spontaneously breathing patients. However this maneuver requires the determination of stroke volume with a fast-response device because the hemodynamic changes may be transient. The Vigileo monitor Vigileo Flotrac Edwards Lifesciences Irvine CA USA analyzes systemic arterial pressure wave and allows continuous stroke volume monitoring. The aims of this study were i to compare changes in stroke volume induced by passive leg raising measured with the Vigileo device and with transthoracic echocardiography and ii to compare their ability to predict fluid responsiveness. Methods Thirty-four patients with spontaneous breathing activity and considered for volume expansion .
