Feasibility of Anesthesiologist-Performed Preoperative Echocardiography for the Prediction of Postinduction Hypotension: A Prospective Observational Study

Figure 2

The maximum inferior vena cava diameter (dIVCmax) was measured as the maximum anterior-posterior dimension at end-expiration using the leading-edge technique (inner edge to inner edge of the vessel wall). The minimum inferior vena cava diameter (dIVCmin) was measured at end-inspiration. The collapsibility index was calculated using the built-in software available on the ultrasound systems. IVC: inferior vena cava; dIVCmax: maximum IVC diameter; dIVCmin: minimum IVC diameter.
