Ultrasound of the Inferior Vena Cava T2 Handbook of Critical Care and Emergency Ultrasound YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-160489-5 LK accessanesthesiology.mhmedical.com/content.aspx?aid=56300602 RD 2024/04/19 AB Ultrasound evaluation of the inferior vena cava (IVC) provides rapid, noninvasive assessment of a patient's hemodynamic status at the bedside. The size of the IVC and its respiratory variability has been shown to correlate with right atrial pressure (RAP) and intravascular volume. These observations are valuable in estimating RAP, detecting changes in intravascular volume, and monitoring a patient's response to volume resuscitation.
