Normal ivc with 50% collapse with sniff

Web26 de jun. de 2024 · It is common practice in echocardiography to estimate the right atrial (RA) pressure by examining the inferior vena cava (IVC) size and its response to respiration. A dilated IVC (>2 cm) has been found to indicate high RA pressure, particularly when there is no collapse during inspiration. 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 …
