A bedside IVC ultrasound was performed to assess volume status in setting of fluid overload. The IVC was identified in longitudinal access. The IVC was plethoric with less than 50% collapse with respirophasic measurements.

2024年10月21日 · Lung ultrasound performed with IVC assessment may provide a more accurate assessment of intravascular and extravascular volume and can help avoid extreme hypervolemia in patients. The hope is that every POCUS user will be able to use this valuable tool confidently.

Ultrasonographic measurement of inferior vena cava (IVC) diameter and degree of respirophasic collapse was initially utilized by nephrologists and subsequently cardiologists. It has more recently been integrated into several critical care/emergency ultrasound protocols as a non-invasive estimate of central venous pressure (CVP).

As inferior vena cava (IVC) accounts for two-thirds of systemic venous return, it has been proposed as a marker of volaemic status by indirect assessment of central venous pressure or fluid responsiveness.

The inferior vena cava (IVC) is a large, thin-walled, retroperitoneal blood vessel formed by the confluence of the left and right common iliac veins. It carries the deoxygenated blood from the lower body and lower extremities to the right atrium.

2019年5月20日 · Point-of-care ultrasound examination of the inferior vena cava (IVC) offers a rapid, noninvasive determination of right atrial pressure to guide assessment of volume status and volume responsiveness.

2024年3月25日 · In this Five Minute Sono, we demonstrate how to use ultrasound to evaluate the inferior vena cava (IVC). The primary goal is to estimate central venous pressure (CVP), which can help determine a patient’s fluid tolerance.

2024年11月28日 · The inferior vena cava (IVC) is a large, thin-walled vein that returns blood from the lower body to the heart. The hepatic portion of the IVC (just above the diaphragm) is the optimal site for ultrasound measurement.

IVC <1 cm in Trauma is associated with a high likelihood of Hemorrhage requiring Blood Transfusion; IVC <1.5 cm suggests volume depletion; IVC >2.5 cm suggests volume overload; Inferior vena cava (IVC) normally collapses more than 50% with inspiration or sniffing. Consider measuring in M-Mode

2023年6月29日 · IVC ultrasound is useful for answering whether patients may be intravascularly volume depleted or not, as well as whether patients may be volume overloaded or not. IVC ultrasound may be combined with other ultrasound techniques to assess intravascular as well as extravascular volume status.
