Correlation of Ultrasonography Indices of Venous Congestion With Intra-abdominal Pressure in ICU Patients.

The goal of this prospective observational study is to examine the potential association between intra-abdominal pressure and venous congestion as assessed by abdominal ultrasound, in critically ill patients in the Intensive Care Unit (ICU). The main question it aims to answer is whether there is association between intra-abdominal pressure and Venous Excess Ultrasound (VExUS) score. Participants will be sonographically assessed and their intra-abdominal pressure measured once within the first 3 days of ICU admission.
