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 کاملThe Diffusing Characteristics and Pressure-volume Relationships of the Pulmonary Capillary Bed in Mitral Valve Disease.
In 1957, Forster, Roughton, and their associates reported a method of estimating pulmonary capillary blood volume (Vc) and diffusing capacity of the alveolar-capillary membrane (DM) by measuring the diffusing capacity of the lung for carbon monoxide (DL) at varying levels of alveolar oxygen tension (1, 2).1 Since then there hlave been a number of reports on the behavior of membrane diffusion an...
متن کاملThe pulmonary diffusing capacity in congenital and rheumatic heart disease.
THE pulmonary diffusing capacity (DL ) is a measureinent relating the flow rate of gas across the alveolo-capillary membrane to the pressure gradient. Estimation of DL is possible by a variety of teehuies.l and in recent years it has resulted in a materially improved understanding of diffuse pulmonary parenchymal disease2 and of the effect of chronic airway obstruction on the pulmonary parenchy...
متن کاملMembrane diffusing capacity and pulmonary capillary volume in rheumatoid disease.
In some patients with rheumatoid disease gas transfer across the lungs is abnormal. We measured the membrane component of gas transfer (Dm) and pulmonary capillary volume (Vc) in 48 patients with rheumatoid arthritis and in 48 normal volunteers matched for age, sex, and smoking habits. Volunteers had normal chest radiographs and normal forced expiratory volume in one second and vital capacity. ...
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...
