A second comparison was performed 90–180 min later. The outcomes assessed included the correlations between SVV with the automated IVC-DI and the manual IVC-DI, respectively before and after fluid challenge, as well as the accuracy of FR according to the automated and manual IVC-DI.

Before the fluid challenge, a negative correlation between automated and manual IVC-CI was observed (r= -0.141, p-value= 0.328) with a concordance rate of 98%, while the correlation became positive after fluid challenge (r= 0.172, p-value= 0.233) with a concordance rate of 98%. After fluid challenge, SVV correlation with automated IVC-DI and manual IVC-DI was positive, with the latter being statistically significant (r= 0.352, p-value= 0.012).
