Republication: Correlations between venous collapsibility and common hemodynamic and ventilatory parameters: A multivariable assessment

Abstract

Introduction: Although the venous collapsibility index (VCI) and central venous pressure (CVP) have been shown to correlate reasonably well, little has been reported on the relationships between VCI and other commonly used hemodynamic variables (i.e., HR, blood pressure). This is a retrospective, post hoc analysis of data from a recently completed 3-year prospective study of VCI in critically ill and injured patients. Materials and Methods: A total of 267 previously recorded data pairs in a group of 82 adults (≥18 to Results: Male patients had significantly greater maximum IVC diameters (2.12 ± 0.89 cm) than female patients (1.81 ± 0.61 cm,P 50%) more accurately correlated to expected SBP and DBP behavior. Conclusions: These preliminary results suggest that DBP may correlate with volume status-based VCI behavior than either SBP or MAP and that VCI may be more accurate in patients experiencing intravascular volume depletion. While these findings are not entirely surprising, further studies are warranted to improve our understanding of the clinical implications and relevance of these findings.
