WebIVC maximum diameter <2.1 cm, that collapses >50% with or without a sniff is inconsistent with intravascular volume overload and suggests normal mean RAP 0 to 5 mmHg, while IVC CI <20% (with moderate to large IVC diameter) with spontaneous inspiration or mechanical ventilation is inconsistent with intravascular volume depletion and suggests …

WebCombining these two parameters allows a simplified method for estimating a reasonable RA pressure in many patients. The IVC diameter should be measured about 1–2 cm from the caval–atrial junction (Fig. 15). An IVC diameter of ≤ 2.1 cm that collapses > 50% with a sniff supports an estimated RA pressure of 3 mm Hg (range, 0–5 mm Hg WebF4: Collapse of inferior vena cava.
