Method for evaluating volume responsiveness during the passive leg raising test

Accurate fluid assessment is essential in critically ill patients, as both fluid insufficiency and fluid excess can result in adverse outcomes. The passive leg raising test (PLR) is a dependable and simple method of evaluating fluid responsiveness. Its accuracy and specificity have been validated over the past decade. Consequently, we have compiled a list of indicators that can be used to predict fluid responsiveness. By selecting more suitable hemodynamic indicators, fluid therapy can be more effectively guided.
