Dynamic effects of positive-pressure ventilation on canine left ventricular pressure-volume relations.
Positive-pressure ventilation (PPV) may affect left ventricular (LV) performance by altering both LV diastolic compliance and pericardial pressure (Ppc). We measured the effect of PPV on LV intraluminal pressure, Ppc, LV volume, and LV cross-sectional area in 17 acute anesthetized dogs. To account for changes in lung volume independent of changes in Ppc and differences in contractility, measure...
متن کاملVolume-dependent effects of positive airway pressure on intracavitary left ventricular end-diastolic pressure.
To test the hypothesis that the effects of positive end-expiratory airway pressure (PEEP) on intracavitary left ventricular end-diastolic pressure (LVEDP) depend on the ventricular filling conditions under which PEEP is applied, the effects of PEEP on pressure in and around the left ventricle were determined before and after stepwise expansion of intravascular blood volume in 10 closed-chest do...
متن کاملMuscle stiffness determined from canine left ventricular pressure-volume curves.
We measured pressure-volume curves in nine excised dog ventricles and stress-strain curves in two to five muscle specimens from each ventricle to verify a derived formula that relates muscle stiffness to the ventricular pressure-volume curve. The assumptions underlying this formula are: (1) the ventricle is a uniform spherical shell, (2) all muscle fibers carry average stress and deform as if t...
متن کاملLeft ventricular diastolic pressure-volume relations in man.
Diastolic function of the left ventricle was analysed in patients with different cardiac diseases: acute and chronic volume overload (in aortic and mitral incompetence), pressure overload and inappropriate ventricular hypertrophy (aortic stenosis and hypertrophic cardiomyopathy), congestive cardiomyopathy, and constrictive pericarditis. Most patients were receiving digitalis therapy at the time...
متن کاملLeft Ventricular Filling and Diastolic Pressure-Volume Relations
In 7 conscious dogs, left ventricular diastolic volume (V) was estimated by taking biplane cineradiographs with the left ventricular cavity previously outlined by permanent radiopaque markers. Left ventricular pressure (P) was measured with an implanted miniature transducer. There were two rapid filling periods during early and late diastole; little filling occurred during the middle third of d...
