To determine the possibility of non-invasive estimation of central venous pressure (CVP) through inferior vena cava (IVC) analysis, using transthoracic echocardiography (TTE). ⋯ IVC analysis is a possible way to non-invasively estimate CVP in a medical /surgical ICU. However, patients with right ventricular enlargement and admitted with chronic respiratory failure present a lack of agreement between IVC parameters and low values of CVP. IVC dimension is a marker of chronic disease and IVC index correlated better with CVP.
