Prospective comparison of noninvasive, bedside ultrasound methods for assessing central venous pressure.

PURPOSE To prospectively evaluate the accuracy of noninvasive central venous pressure (CVP) assessment by compression ultrasound of a forearm vein (CUS), inferior vena cava (IVC-C) and internal jugular vein collapsibility (IJV-C) compared to invasive CVP measurement (invCVP) as the gold standard. MATERIALS AND METHODS CUS, IVC-C and IJV-C were performed… (More)
