Inaccuracy of wedge pressure as an index of pulmonary capillary pressure.
The wedge and left atrial pressures were compared in 1'2 subjects with congenital and aequired heart disease; all experiments were carried out with closed chest under basal conditions. A poor correlation between the wedge and left atrial pressures was mnoted in over half the patients. The wedge pressure is especially inaccurate in mitral stenosis with marked elevations in left atrial pressure.
متن کاملInfluence of artificial ventilation on the pulmonary capillary wedge pressure.
COMMUNICATIONS TO THE EDITOR 693 operation. Preston’s insinuation that cardiologists and surgeons are recommending aortocoronary bypass surgery for personal economic reasons is one of the most insulting things that I have ever read in a medical journal. Did it ever occur to him that the results he reads about in journals and sees in government-funded hospitals might not be the same as the resul...
متن کاملPulmonary capillary wedge pressure augments right ventricular pulsatile loading.
BACKGROUND Right ventricular failure from increased pulmonary vascular loading is a major cause of morbidity and mortality, yet its modulation by disease remains poorly understood. We tested the hypotheses that, unlike the systemic circulation, pulmonary vascular resistance (R(PA)) and compliance (C(PA)) are consistently and inversely related regardless of age, pulmonary hypertension, or inters...
متن کاملComparison of left atrial pressure and wedge pulmonary capillary pressure. Pressure gradients between left atrium and left ventricle.
Simultaneous records of wedged pulmonary capillary pressure and left atrial pressure have been made in I2 patients. The pressure changes in the left atrium preceded those in the pulmonary capillary bed by o-o6 to O0I4 sec. This delay, together with the damping of the wedged pulmonary capillary pressure, may result in a false appearance of an end-diastolic gradient between the left atrium and th...
متن کاملEffective 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...
