Maximal Diffusing Capacity of the Lung for Carbon Monoxide.
The measurement of co uptake (VCO and DLCO) from alveolar gas is a unique way to noninvasively assess pulmonary vascular function, specifically the functional volume of the pulmonary capillary bed. Proper interpretation of results, however, needs to account for inherent assumptions regarding co distribution and timing procedures. Moreover, reasonable airway mechanics, lung volumes, and patient ...
متن کاملImportance of appropriately adjusting diffusing capacity of the lung for carbon monoxide and diffusing capacity of the lung for carbon monoxide/alveolar volume ratio for lung volume.
In their report on cardiac sarcoidosis, Smedema et al (July 2005)1 remarkably conclude that patients without cardiac symptoms do not require more sensitive studies to detect heart disease. This report, while of interest, is limited by a patient follow-up that varied widely from 3 to 54 months. Since this study does not well characterize the natural history of asymptomatic cardiac sarcoidosis an...
متن کاملApplication of carbon monoxide diffusing capacity in the mouse lung.
In the past decade the mouse has become the primary animal model of a variety of lung diseases. To assess various mechanisms underlying such pathologies, it is essential to make functional measurements that can reflect the developing pathology. In this regard, the diffusing capacity for carbon monoxide is a variable that directly reflects structural changes in the lung. Although measurement of ...
متن کامل[The measurement of pulmonary diffusing capacity for carbon monoxide].
The pulmonary diffusing capacity for oxygen (DLo,) is of great physiological and clinical significance (1). Its measurement, however, is relatively complex (2). Pulmonary diffusing capacity for carbon monoxide (DLco) which, it is usually assumed,' can be converted to DL02 from the known solubilities and molecular weights of the two gases, is, in general, more readily measured. Further, since th...
متن کاملAdjusting diffusing capacity of the lung for carbon monoxide for haemoglobin level.
The joint statements on lung function testing by the American Thoracic Society (ATS)/European Respiratory Society (ERS) Task Force provided useful recommendations for standardisation of the tests in daily practice [1]. However, the equations for adjusting diffusing capacity of the lung for carbon monoxide (DL,CO) for the haemoglobin (Hb) level (equations 13 and 14 in the original document) may ...
