Pulmonary Diffusing Capacity in Mitral Valve Disease.
While the pulmonary diffusing capacity is now accepted as an important test of lung function, comparatively little application of the test has been made in patients suffering from cardiac disorders. Bates, Boucot, and Dormer (1955) were the first to describe a simple and reliable means for estimating gaseous diffusion, using the steady state carbon monoxide technique. MacNamara, Prime, and Sinc...
متن کاملPulmonary diffusing capacity in left ventricular dysfunction.
The purpose of this study was to determine whether there are any consistent spirometric or Dsb findings in patients with LV dysfunction characterized by a clinical diagnosis of CHF and an EF less than 40 percent. We performed spirometry and Dsb in 34 patients, and found that EF correlated only with Dsb. When we separated the patients into those with rales and those without, Dsb correlated stron...
متن کاملPulmonary diffusing capacity in disorders of the pulmonary circulation.
The pulmonary diffusing capacity for carbon monoxide was measured by single breath (DcoSB) and steady state (DcoSS) techniques in 48 patients with various pulmonary circulatory disorders and the results compared with the type of hemodynamic abnormality. Patients with pure inflow obstruction (primary pulmonary hypertension, recurrent pulmonary emboli) had the lowest Dco (mean DcoSB = 14.3 ml/min...
متن کاملFunctional Significance of a Low Pulmonary Diffusing Capacity for Carbon
Diffusing capacity of the lungs imposes a theoretical limit to oxygen consumption, causing oxygen saturation of arterial blood to fall sharply if this limit is approached (1). The diffusing surface of the normal lung is so large, however, that at sea level oxygen capacity of the blood and the cardiac output rather than diffusing capacity create the major bottleneck to oxygen transport (2). Diff...
متن کاملDiffusing capacity in alcoholics.
It’s amazing to me how in this age of computers that an article as specific as yours was somehow missed in our personal review and in our automated computer search. However, I have had the occasion recently to review it and agree with you that your report on the effects of angiotensin on left ventricular ejection fraction in both man and dog was well described. Although your methods of determin...
