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

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.

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

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

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.

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.

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.

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.
