In acute circulatory failure, passive leg raising PLR is a test that predicts whether cardiac output will increase with volume expansion [ 1 ]. However, no fluid is infused and the hemodynamic effects are rapidly reversible [ 1 , 3 ], thereby avoiding the risks of fluid overload. This test has the advantage of remaining reliable in conditions in which indices of fluid responsiveness that are based on the respiratory variations of stroke volume cannot be used [ 1 ], like spontaneous breathing, arrhythmias, low tidal volume ventilation, and low lung compliance. The method for performing PLR is of the utmost importance because it fundamentally affects its hemodynamic effects and reliability. In practice, five rules should be followed. A study that did not comply with this rule misleadingly reported a poor reliability of PLR [ 4 ]. The best method for passive leg raising, indicating the five rules to be followed.
