None:
Both venous excess ultrasound (VExUS) and central venous pressure (CVP) can assess venous congestion from different perspectives. CVP provides continuous and simple monitoring of the risk of congestion and is easily repeatable in patients with a central venous catheter. In contrast, VExUS offers an intermittent, organ-level evaluation of established congestion and may help identify the venous waterfall phenomenon. Furthermore, assessment of pulmonary congestion should not be overlooked.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
