Venous Congestion
Venous congestion is quantified by a high central venous pressure (CVP) and its monitoring is essential to assess the hemodynamic status in patients with heart failure, pulmonary hypertension, and with impaired renal and hepatic function [1,2,3,4,5,6].
The standard technique for measuring CVP is invasive and requires the insertion of a catheter into a subclavian or internal jugular vein, leading to potential complications.
Current non-invasive CVP measurements based on ultrasonography have the limitation of being operator-dependent, inaccurate and not suitable for frequent monitoring at home [7,8]
