Does passive leg raising followed by measurement of cardiac output predict fluid responsiveness in hemodynamically unstable adults?
Passive leg raising combined with cardiac output measurement is highlighted as the most useful test for predicting fluid responsiveness in hemodynamically unstable adults.
Passive leg raising followed by measurement of cardiac output or related parameters may be the most useful test for predicting fluid responsiveness in hemodynamically unstable adults. The usefulness of respiratory variation in the vena cava requires confirmatory studies.
Bentzer et al. (Tue,) studied this question.
