The pulmonary venous wedge pressure in pulmonary arterial hypertension

Catheterization and Cardiovascular Diagnosis, 1977
AbstractThe comparability of the main pulmonary artery pressure (PAP) and the pulmonary venous wedge pressure (PVWP) was assessed during cardiac catheterization in 89 patients with pulmonary artery hypertension (PAH) and increased pulmonary blood flow.

The Critical Role of Pulmonary Artery Wedge Pressure Saturation In The Standardization of Pulmonary Artery Wedge Pressure Measurement

Journal of Cardiac Failure, 2020
Introduction Inadequate balloon occlusion while measuring pulmonary artery wedge pressure (PAWP) during right heart catheterization (RHC) may lead to inaccurate measures and clinically relevant misdiagnosis of disease. Following the 6th World Symposium on Pulmonary Hypertension (PH) recommendations, we instituted a standard of care clinical protocol ...

Pulmonary “Capillary” Wedge Pressure Not the Pressure in the Pulmonary Capillaries

Chest, 1991
In 1949, Hellems, Haynes, and Dexter proposed that the pressure in a catheter wedged so as to occlude a pulmonary artery was an "estimate" of the pressure in the pulmonary capillaries. Their report led to the designation of this pulmonary artery wedge pressure as the pulmonary "capillary" wedge pressure.

Artifacts in the measurement of pulmonary artery wedge pressure

Critical Care Medicine, 1978
Pulmonary artery wedge pressure (PAWP) will only reflect left atrial pressure (LAP) if continuity of fluid exists from the catheter tip to the left atrium. Either increased airway pressure or decreased hydrostatic pressure may lead to discontinuity of the fluid column and midinterpretation of PAWP. Simultaneous measurements of PAWP and LAP were made in

Pulmonary hypertension in sepsis: measurement by the pulmonary arterial diastolic-pulmonary wedge pressure gradient and the influence of passive and active factors.

Chest, 1978
To examine the relative roles of passive factors (flow; filling pressures of left side of heart) and active factors (acidosis; arterial unsaturation) in the genesis of pulmonary hypertension when associated with sepsis, 37 patients with sepsis and 24 ...

Measurement of pulmonary wedge pressure by the flow directed Swan-Ganz catheter.

Cardiovascular Research, 1972
Forty patients were studied by the Swan–Ganz flow directed catheter and the wedge pressure was shown to be identical with that obtained by a Cournand and correlated well with the direct left atrial pressure.

Central venous pressure and pulmonary wedge pressure in critical surgical illness. A comparison.

Archives of Surgery, 1974
To assess the reliability of the central venous pressure (CVP) as an adequate guide to cardiac performance, we inserted a balloon-tipped pulmonary artery catheter (Swan-Ganz 7F, 110 cm) in 27 critically ill surgical patients, and simultaneously measured ...

Wedge Pressure Measurement in Obstructive Pulmonary Disease

Chest, 1974
Mean pulmonary capillary wedge absolute pressures relative to atmosphere were compared with effective wedge pressures in 19 patients with respiratory failure secondary to chronic obstructive pulmonary disease to determine whether a mean wedge or effective wedge pressure provided the most useful diagnostic information when intrathoracic pressure changes

Echocardiographic Estimates of Pulmonary Artery Wedge Pressure

New England Journal of Medicine, 1981
IN patients free of pulmonary venous occlusive disease or mitral-valve obstructive disease or both, the pulmonary artery wedge pressure reflects the left atrial pressure and thus the left ventricular filling pressure. Care of a critically ill patient with a cardiac disorder frequently requires measurement of the pulmonary artery wedge pressure by right-

Central venous pressure and pulmonary wedge pressure. A comparative study in anesthetized surgical patients.

Archives of Surgery, 1976
To determine the reliability of central venous pressure (CVP) as a guide to fluid therapy during an operation, repeated and simultaneous CVP and pulmonary wedge pressure (PWP) measurements were made with a Swan-Ganz catheter in 13 relatively elderly ...
