Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch. [1]
The standard pulmonary artery catheter has two lumens (Swan-Ganz) and is equipped with an inflatable balloon at the tip, which facilitates its placement into the pulmonary artery through the flow of blood. The balloon, when inflated, causes the catheter to "wedge" in a small pulmonary blood vessel.
The pulmonary artery wedge pressure (also called pulmonary artery occlusion pressure or PAOP) is a measurement in which one of the pulmonary arteries is occluded, and the pressure downstream from the occlusion is measured in order to approximate the left atrial pressure. [6]
A pulmonary artery wedge pressure being less than 15 mmHg (also measured by right heart catheterization) excludes post-capillary bed (in the veins distal to the capillary bed) pulmonary hypertension. Pulmonary arterial hypertension is a subgroup of pulmonary hypertension and is categorized as World Health Organization as group 1. [ 3 ]
The pulmonary artery pressure (PA pressure) is a measure of the blood pressure found in the main pulmonary artery. This is measured by inserting a catheter into the main pulmonary artery. [13]: 190–191 The mean pressure is typically 9–18 mmHg, [14] and the wedge pressure measured in the left atrium may be 6–12 mmHg.
pressure range (in mmHg) [5] Central venous pressure: 3–8 Right ventricular pressure: systolic: 15–30 diastolic: 3–8 Pulmonary artery pressure: systolic: 15–30 diastolic: 4–12 Pulmonary vein/ Pulmonary capillary wedge pressure. 2–15 Left ventricular pressure: systolic: 100–140 diastolic: 3–12
Pulmonary Artery Wedge Pressure can show if there is congestive heart failure, mitral and aortic valve disorders, hypervolemia, shunts, or cardiac tamponade. [ 37 ] Remote, indirect monitoring of blood flow by laser Doppler
pulmonary artery wedge pressure < 18 mmHg (obtained by pulmonary artery catheterization) if no measured LA pressure available, there must be no other clinical evidence to suggest elevated left heart pressure. If Pa O 2:Fi O 2 < 300 mmHg (40 kPa), then the definitions recommended a classification as "acute lung injury" (ALI).
