Methods: A prospective observational study was performed in the intensive care unit
between December 2017 and March 2018. Mechanically ventilated patients were enrolled …

OBJECTIVE: Ultrasonography has been suggested as a useful noninvasive tool for the
detection and follow-up for hypovolemia. Two possible sonographic markers as a surrogate …

Background/aim: To compare the inferior vena cava (IVC) indices, identify their variation
rates at positive pressure values and accurate predictive values for the volume status in …

Purpose Assessment of the inferior vena cava (IVC) respiratory variation may be clinically
useful for the estimation of fluid-responsiveness and venous congestion; however, imaging …

Aims: We therefore evaluated the limits of agreement between the IVC diameter
measurement and variation in subcostal and that by the lateral transhepatic view. Settings …

Objective The objective of this study is to find a correlation between internal jugular vein
(IJV) and common carotid artery (CCA) diameter ratio and central venous pressure (CVP) …

Background Ultrasound of the inferior vena cava (IVC) is a noninvasive and rapidly
obtainable method of intravascular volume assessment; however not all patients can lie …

Background Intraoperative hypotension increases 30-day mortality and the risks of
myocardial injury and acute renal failure. Patients with inadequate volume reserve before …

Methods Volunteers were evaluated by three experienced emergency physician
sonographers (EP). Gray scale (B-mode) and motion-mode (M-mode) diameters were …

Background The inferior vena cava (IVC) parameters, including its diameter and
collapsibility index have been evaluated for fluid status for over 30 years, but little is known …
