pulmonary arteriolar vascular resistance when calculated from main PAP; 2) properly performed PVWP determination can define the lower limit of mean pressure in the ipsilateral branch pulmonary artery; 3) a PVWPm <30 mm Hg. usually indicates an ipsilateral PAPm <40 mm Hg; 4) a PVWPm >30 mm...
Pulmonary hypertension is often caused by increased pulmonary vascular resistance. To calculate this, pulmonary blood flow (usually measured by the thermodilution technique), pulmonary artery pressure and pulmonary venous pressure (PCWP) measurements are required. Pulmonary hypertension can also result from ...

It may not become apparent that a patient with low cardiac output has pulmonary hypertension until the cardiac output is improved. Not all maneuvers that reduce PVR will benefit the patient. Any physiologic maneuver that increases the wedge pressure more than the mean PAP will decrease PVR, ...
In the group of subjects with a sense of fatigue as the end-point, the pulmonary wedge pressure was normal in the control period and rose minimally during the exercise. Arterial gas tensions were normal in the control, fatigue and end-fatigue periods.3.3. In the group of subjects ...

To provide a description of post-capillary pulmonary hypertension (PH) patients and to evaluate the role of the gradient between diastolic pulmonary arterial pressure (dPAP) and pulmonary wedge pressure (Ppw) in the assessment of post-capillary PH. We reviewed the clinical, echocardiographic and ...

OBJECTIVE: To establish if agreement exists between central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP) measurements in severe hypertension in pregnancy as analyzed by tests of bias, precision, and 95% limits of agreement. METHODS: In a prospective study, CVP and PCWP data...
