Figure 2From: Changes in aortic blood flow induced by passive leg raising predict fluid responsiveness in critically ill patientsRelationship between changes in ABF induced by PLR and VE. Abbreviations: ABF = aortic blood flow; PLR = passive leg raising; VE = volume expansion. Results are expressed as percentage variation from Base 1 value for PLR and from Base 2 value for VE.Back to article page
