Mechanical ventilation causes changes in left ventricular preload leading to distinct variations in left ventricular stroke volume and systolic arterial pressure. Retrospective off-line quanti®cation of systolic arterial pressure variations (SPV) has been validated as a sensitive method of predicting left ventricular response to volume administration. We report the real-time measurement of left ventricular stroke volume variations (SVV) by continuous arterial pulse contour analysis and compare it with off-line measurements of SPV in patients after cardiac surgery. Methods. SVV and SPV were determined before and after volume loading with colloids in 20 mechanically ventilated patients. Results. SVV and SPV decreased signi®cantly after volume loading and were correlated (r=0.89; P
