Importance 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 کاملPredicted values for lung diffusing capacity in healthy children.
Lung diffusing capacity was measured in 92 healthy Caucasian children (52 boys and 40 girls), ranging in age from 6 to 17 years, using the single breath carbon monoxide technique (DLCO). Multiple regression equations were developed to predict the DLCO value. Standing height, gender, weight, and age were significant factors in the prediction of DLCO. Sitting height was not a significant covariat...
متن کاملMaximal 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 کاملRecruitment of lung diffusing capacity: update of concept and application.
Lung diffusing capacity (DL) for carbon monoxide (DLCO), nitric oxide (DLNO) or oxygen (DLO2) increases from rest to peak exercise without reaching an upper limit; this recruitment results from interactions among alveolar volume (VA), and cardiac output (q), as well as changing physical properties and spatial distribution of capillary erythrocytes, and is critical for maintaining a normal arter...
متن کاملMeasurement variability in single-breath diffusing capacity of the lung.
STUDY OBJECTIVES The single-breath diffusing capacity of the lung (DLCO) is a commonly performed pulmonary function test. The current American Thoracic Society (ATS) recommendations for reproducibility of DLCO measurements suggest that two measurements for the DLCO agree within 10% or 3 mL/min/mm Hg of the average value. The European Respiratory Society (ERS) recommends that two measurements sh...
