Why the study?
Does passive leg raising predict fluid responsiveness in critically ill ventilated patients?
Does passive leg raising predict fluid responsiveness in critically ill ventilated patients?
Passive leg raising is a reliable predictor of fluid responsiveness in critically ill patients, even when arrhythmias or spontaneous breathing render pulse pressure variation unreliable.
The changes in aortic blood flow induced by PLR predict preload responsiveness in ventilated patients, whereas with arrhythmias and spontaneous breathing activity, respiratory variations of arterial pulse pressure poorly predict preload responsiveness.
