Key result
Sonographic IVC diameter and collapsibility strongly correlate with CVP, especially in spontaneously breathing patients.
Why the study?
The study sought to determine the correlation of sonographic inferior vena cava diameter and collapsibility index with central venous pressure in spontaneously breathing and mechanically ventilated surgical ICU patients.

Does sonographic evaluation of IVC diameter and collapsibility index correlate with central venous pressure in critically ill patients?
Effect estimate: r=0.850 (max diameter) and r=-0.899 (collapsibility) in spontaneously breathing; r=0.779 and r=-0.725 in mechanically ventilated
p-value: p=<0.001
Sonographic evaluation of IVC diameter and collapsibility index is a reliable, non-invasive method to assess intravascular volume status, particularly in spontaneously breathing critically ill patients.
Afia Arshed Dodhy (2021) conducted a cross-sectional in Critically ill patients in surgical ICU (n=126). Sonographic evaluation of inferior vena cava diameter and collapsibility index was evaluated on Correlation with central venous pressure (r=0.850 (max diameter) and r=-0.899 (collapsibility) in spontaneously breathing; r=0.779 and r=-0.725 in mechanically ventilated, p=<0.001). Sonographic evaluation of inferior vena cava diameter and collapsibility index significantly correlated with central venous pressure (p<0.001), with stronger correlation in spontaneously breathing patients.
