Figure 6

Individual values of ∆VTI50 (%) (A), ∆SV50 (%) (B), and ∆CO50 (%) (C) after infusion of 50 ml of fluid over 10 seconds changed in patients with volume expansion-induced changes in stroke volume (SV) of at least 15% (responders) and less than 15% (non-responders). ∆CO50, variation of cardiac output after infusion of 50 ml of fluid over 10 seconds; ∆SV50, variation of stroke volume after infusion of 50 ml of fluid over 10 seconds; ∆VTI50, variation of velocity time index after infusion of 50 ml of fluid over 10 seconds; CO, cardiac output; VTI, aortic velocity time index.
