“…Similarly, He et al demonstrated that IVC distensibility index is affected by TV and is most accurate at TV of 9 mL/kg [ 27 ]. On the other hand, an observational study on 79 critically ill patients who were on mechanical ventilation showed that LVOT VTI variations can be taken into account when predicting fluid responsiveness at PEEP level ranging between 0 and 10 cm H 2 O [ 28 ].…”

Assessing the volume status in critically ill patients is the key to maintain the stability of the hemodynamics; however, it can be challenging to view the complexity of cases and the diversity of shock etiology. Multiple noninvasive means have been used to study the effectiveness of volume resuscitation, but none of them have been used as gold standard. We aim to illustrate the most used techniques: left ventricular outflow tract velocity time integral versus inferior vena cava compressibility index, and highlight their limitations and strengths. These tools are both operator-dependent and might be affected by several factors including ventilator settings.
