Influence 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 کاملInaccuracy 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 کاملThe Effect of Airway Pressure Release Ventilation on Pulmonary Catheter Readings: Specifically Pulmonary Capillary Wedge Pressure in a Swine Model
Background. Airway pressure release ventilation (APRV) is a mode of mechanical ventilation that theoretically believed to improve cardiac output by lowering right atrial pressure. However, hemodynamic parameters have never been formally assessed. Methods. Seven healthy swine were intubated and sedated. A baseline assessment of conventional ventilation (assist control) and positive end-expirator...
