Fluid Responsiveness
Conditions
Brief summary
The aim of the study is to evaluate whether changes in Perfusion Index (PI) and Pleth Variability Index (PVI) during passive leg raising test can predict fluid responsiveness in spontaneously breathing patients. Fluid responsive patients are defined as showing an increase in cardiac output \>10% during a passive leg raising test, measured semi-invaseively with FloTrac® (Edwards LifeSciences. Irvine, United States).
