Figure 3From: A 10-second fluid challenge guided by transthoracic echocardiography can predict fluid responsiveness(A) Correlation between ∆VTI50 (%) and ∆VTI500 (%). (B) Correlation between ∆CO50 (%) and ∆CO500 (%). ∆CO50, variation of cardiac output after infusion of 50 ml of fluid over 10 seconds; ∆CO500, variation of cardiac output after infusion of 500 ml fluid over 15 minutes; ∆VTI50, variation of velocity time index after infusion of 50 ml of fluid over 10 seconds; ∆VTI500, variation of velocity time index after infusion of 500 ml of fluid over 15 minutes.Back to article page
