Fig. 3From: Capillary refill time variation induced by passive leg raising predicts capillary refill time response to volume expansionROC curves of CRT and ∆CRT-PLR to predict CRT response to volume expansion. CRT, capillary refill time; CRT responders, response to volume expansion defined as patients showing a decrease in CRT after VE of at least 25%; PCO2gap, central venous-to-arterial carbon dioxide difference; PLR, passive leg raising; VE, volume expansionBack to article page
