Acquiring the IVC view with Ultrasound:
Place the probe in the subxiphoid position and get the IVC in the long-axis view. Most people will know how to perform an IVC exam,
Interpretation of IVC Measurements:
Evaluate the size and collapsibility of the IVC.
If the maximum IVC diameter is <2cm, then there is no significant venous congestion (at least cardiac related). You can stop the exam here and the VExUS score is 0.
If IVC is >2cm then proceed to the next steps.
