Dynamic arterial elastance as a predictor of arterial pressure response to fluid administration: a validation study
IntroductionFunctional assessment of arterial load by dynamic arterial elastance (Eadyn), defined as the ratio between pulse-pressure variation (PPV) and stroke volume variation (SVV), has recently been shown to predict the arterial pressure response to volume expansion (VE) in hypotensive preload-dependent patients. However, since both SVV and PPV were obtained from pulse-pressure analysis, a mathematical coupling factor could not be excluded. We therefore designed this study to confirm whether Eadyn, obtained from two independent signals, allows the prediction of arterial pressure response to VE in fluid-responsive patie...
