Figure 2From: Predicting preload responsiveness using simultaneous recordings of inferior and superior vena cavae diametersIndividual values for the inferior vena cava distensibility index according to the fluid responsiveness. Patients were divided into two groups: responders (R) or nonresponders (NR). T0, Baseline; T1, After volume expansion. Individual values are indicated by open circles, and median ± interquartile range values are marked by closed circles. *P < 0.05 R vs. NR.Back to article page
