Also, within the ultrasound community, there is not yet standardization of the location of IVC diameter measurements or probe orientation (long versus short axis) when taking IVC measurements.

This prospective, observational study investigated how visual estimates on bedside ultrasound of LV function and IVC respiratory dynamics correlated with more detailed, quantitative measurements.

Qualitative Estimates of IVC Collapse In the busy ED, quick assessments can lead to swift and appropriate therapies. Like the qualitative arm of the Fields study above, the next study looks at ...

A review of the use of ultrasound in measuring the inferior vena cava as a surrogate of intravascular volume status to determine how best to integrate these measurements into the practice of medicine.

Extrapolating these results to the ED population is difficult, so some investigators have sought to correlate IVC collapse with measurements of central venous pressure (CVP).

Criteria for inclusion were prospective study design, use of adult ED patients, and report of IVC diameter measurements by US in both hypotensive and control patients.

US measurements were performed with the patient in a supine position, and both inspiratory and expiratory IVC diameters were measured 2-3cm caudal to the right atrial border.

Analysis of M-mode diameter measurements revealed that IVC-US experience and the patients’ volume status were significantly associated with inter-rater reliability.

Introduction Measuring the IVC and Measurement Reliability Inferior Vena Cava Percentage Collapse During Respiration Is Affected by the Sampling Location: An Ultrasound Study in Healthy Volunteers ...

The purpose of this study was to assess whether IVC diameters correlated with invasive measurements of hemodynamic status and markers of pulmonary edema or acute lung injury.
