The Trendelenburg position is used to distend the central veins, improving both success and safety of vascular cannulation. The purpose of this study is to measure the cross-sectional area of the internal jugular vein (IJV) in three different positions, using surface ultrasound.

Ultrasound may be useful for noninvasively determining the central venous pressure. We intend to compare the clinical examination of the neck veins; ultrasound delineation of the internal ...
In patients admitted to a coronary care unit, what is the correlation coefficient and limits of agreement for paired measurements of peripheral venous pressure and central venous pressure ...
Recent studies indicated the central venous pressure (CVP) as a prognostic marker. Therefore, we retrospectively analyzed the CVP on admission to the intensive care unit (ICU) in cardiac s...
Objectives: 1. To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound. ...
The goal of this research study is to determine the feasibility and accuracy of Mespere Life Science non-invasive central venous pressure monitoring system (Mespere VENUS 2000CVP system) i...
The purpose of our study is to compare the rate of central line-associated blood stream infections and venous thromboembolism in central venous catheters versus peripherally inserted central catheters...
The inferior vena cava (IVC) has a complex three-dimensional (3D) shape, but measurements used to estimate central venous pressure (CVP) remain based on two-dimensional (2D) echocardiographic imaging....
Although central venous pressure (CVP) is a surrogate measure of preload in patients with acute decompensated heart failure (ADHF), it is a multifactorial index influenced not only by fluid volume sta...
Blood pressure has been traditionally measured at peripheral arteries. In the past decade evidence has grown, that central aortic blood pressure may be a more powerful predictor for cardiovascular eve...
Cerebral venous infarction (CVI) is a rare vascular disease, most commonly caused by cerebral venous thrombosis, which leads to brain tissue ischemia and anoxia, followed by necrosis, hemorrhage, and ...
The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
