wedge pressure

It is usually higher than the pulmonary wedge pressure.

"The pulmonary wedge pressure has gone up despite everything.

The increase in pulmonary capillary wedge pressure by 90% points to additional venoconstrictive effects.

See also pulmonary wedge pressure and ventricular pressure.

High cardiac index and pulmonary capillary wedge pressures, however, may lead to false positives by this standard.

A left atrial myxoma will cause an increase in Pulmonary Capillary Wedge Pressure.

Vessel cannula or catheter pressure measurement-pulmonary wedge pressure or in older animal experiments.

This can be done by placing a pulmonary artery catheter for measuring the pulmonary artery wedge pressure.

Cardiac catheterisation showed moderate mitral regurgitation with a pulmonary capillary wedge pressure of 14 mm Hg.

Once the catheter is in the hepatic vein, a wedge pressure is obtained to calculate the pressure gradient in the liver.

The abdominojugular test, when done in a standardized fashion, correlates best with the pulmonary arterial wedge pressure, and therefore, is probably a reflection of an increased central blood volume.

Also, the pulmonary capillary wedge pressure is normal (less than 18 mmHg) in ARDS, but raised in left ventricular failure.

As part of that procedure a hepatic vein wedge pressure is measured with the assumption of no pressure drop across the liver yielding portal vein pressure.

Several studies have shown that pulmonary function and outcome are better in patients that lost weight or pulmonary wedge pressure was lowered by diuresis or fluid restriction.

In a prospective randomized study involving 86 patients who underwent right and left cardiac catheterization, the abdominojugular test was shown to correlate best with the pulmonary arterial wedge pressure.

Every 3 h, measurements of pulmonary capillary wedge pressure (PCWP) were made and cardiac output was determined from thermodilution curves with iced saline in triplicate.

These medications also decrease the heart rate, though their use in patients with severe outflow obstruction, elevated pulmonary artery wedge pressure and low blood pressures should be done with caution.

The right heart catheterization (commonly known as Swan-Ganz catheterization) gives the physician the mean pulmonary capillary wedge pressure, which is a reflection of the left atrial pressure.

Amrinone decreases the pulmonary capillary wedge pressure while increasing cardiac output because it functions as an arterial vasodilator and increases venous capacitance while decreasing venous return.

Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, often presenting with a collapsing pulse.

Thinking she might be having an allergic reaction to the dye, he put in a central line, in case he needed to monitor her wedge pressure with a Swan-Gantz and give her fluids.

Hepatic vein catherterisation showed a hepatic vein wedge pressure of 12-14 mm Hg and inferior vena caval mean pressure of 12-13 mm Hg.

It has also been used to diagnose severity of left ventricular failure and mitral stenosis, given that elevated pulmonary capillary wedge pressure strongly suggests failure of left ventricular output.

In the absence of isolated right ventricular failure, seen in some patients with right ventricular infarction, a positive abdominojugular test suggests a pulmonary artery wedge pressure of 15 mm Hg or greater.

Physiologically, distinctions can be drawn among pulmonary venous pressure, pulmonary artery pressure, pulmonary capillary wedge pressure, and left atrial pressure, but not all of these can be measured in a clinical context.
