Effective pulmonary capillary pressure.
The adult respiratory distress syndrome (ARDS) is almost invariably accompanied by permeability pulmonary oedema, usually appearing in the first few hours [1, 2]. The extent and therefore the seriousness of this oedema is proportional to the filtration of fluid and proteins through the pulmonary vascular endothelium. The extreme sensitivity of this filtration to variations of capillary pressure...
متن کاملPulmonary capillary pressure in pulmonary hypertension
INTRODUCTION Pulmonary capillary pressure (PCP), together with the time constants of the various vascular compartments, define the dynamics of the pulmonary vascular system. Our objective in the present study was to estimate PCPs and time constants of the vascular system in patients with idiopathic pulmonary arterial hypertension (IPAH), and compare them with these measures in patients with acu...
متن کاملIncreased pulmonary venous resistance contributes to increased pulmonary artery diastolic-pulmonary wedge pressure gradient in acute respiratory distress syndrome.
BACKGROUND Pulmonary artery diastolic (PAD)-pulmonary wedge pressure (PWP) gradient has been shown to be increased in sepsis and acute respiratory distress syndrome (ARDS). Because pulmonary venous vasoconstriction induced by endotoxemia in sepsis or postcapillary leukocyte aggregation in ARDS or both can increase pulmonary venous resistance (Rpv), it is possible that the elevated Rpv increases...
متن کاملRelationship between pulmonary artery end-diastolic pressure and left ventricular filling pressure in patients in shock.
Bedside catheterization permitted 56 simultaneous measurements of left ventricular end-diastolic pressure (LVEDP) and pulmonary artery end-diastolic pressure (PAEDP) in 25 patients in shock. Measurements were made over a wide range of heart rates (60-160 beats/min), arterial oxygen tension (P02; 33-562 mm Hg), stroke volumes (9-105 ml), and systolic arterial pressures (65-250 mm Hg), and before...
متن کاملThe Impact of Cardiac Rehabilitation on Pulmonary Artery Systolic Pressure and Left Ventricular End-Diastolic Pressure in Patients after Coronary Artery Bypass Graft Surgery
Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LV...
