Background: Accurate assessment of intravascular volume status is one of the most challenging and important tasks in the care of critically ill patients. There are some invasive and non-invasive parameters for volume status assessment. Central venous pressure (CVP) is an invasive measure for intravascular volume status assessment and has been associated with many complications. The IVC-CI can provide a useful guide for noninvasive intravascular volume status assessment of critically-ill patients. Methodology: This Cross-sectional study was carried out in the ICU, BSMMU after permission from the Institutional Review Board of BSMMU. A total 120 critically-ill patients on positive pressure ventilation in the intensive care unit was assessed for eligibility. All ultrasonographic examinations were performed in the adequately sedated mechanically ventilated patients in supine position by investigator using a portable ultrasound device sonoscape S2. Sonographic evaluation of IVC-CI was performed via an initial B-mode. The maximum and minimum IVC diameter was measured without regard to phase of the respiratory cycle. The CVP was also measured in the supine position immediately after the IVC evaluation. It was used as the reference parameter for stratifying each patient’s intravascular volume status. IVC-CI measurements was grouped by range (<0.20, 0.20 to 0.50, and >0.50) and analyzed for presence of substantial differences in CVP between the three IVC-CI groupings. IVC-CI was correlated with CVP value. Sensitivity and specificity of IVC-CI were also calculated. Results: A total of 48/110 (40%) females and 72/120 (60%) males were included in the study with a mean age of 53.3 ± 13.1 years. The mean central venous pressure maintained was 12.53±3.26 mmHg in group III, 7.05±1.43 mmHg in group I and 2.69±1.06 mmHg in group II with the inferior vena cava collapsibility index (IVC-CI) was 0.59±0.05 in group I, 0.34±0.09 in group II and 0.21±0.11 in group III. The difference was st
