The Diffusing Capacity of the Lungs
The fact that morphological changes occur in the lungs of patients with mitral stenosis has been generally accepted since 1936 when Parker and Weiss described thickening of the capillary basement membrane, scarring and probable loss of capillaries (1). These findings have been confirmed and extended by others (2, 3), yet there is no agreement regarding the physiological and clinical significanc...
متن کاملThe Role of EDD (Exercise Capacity, Dyspnea, and Diffusing Capacity of Lungs for Carbon Monoxide) Index in Pulmonary Fibrosis Secondary to Scleroderma
Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...
متن کاملSpatiotemporal motion estimation for respiratory-correlated imaging of the lungs.
PURPOSE Four-dimensional computed tomography (4D CT) can provide patient-specific motion information for radiotherapy planning and delivery. Motion estimation in 4D CT is challenging due to the reduced image quality and the presence of artifacts. We aim to improve the robustness of deformable registration applied to respiratory-correlated imaging of the lungs, by using a global problem formulat...
متن کاملHistory dependence of vital capacity in constricted lungs.
Measurements of dynamic force-length behavior of maximally activated strips of smooth muscle during oscillatory length changes show that force decreases well below the isometric force during the shortening phase of the oscillation. The magnitude of the decrease depends on the rate of shortening; for slower shortening, the decrease is smaller and force is larger. Modeling of expiratory flow, bas...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
