restrictive lung disease pdf

The key clinical difference between obstructive and restrictive lung disease is the forced expiratory volume at one second (FEV 1) and the forced vital capacity (FVC) ratio, which is decreased in obstructive lung disease and normal in restrictive lung disease. 0000050737 00000 n 0000021421 00000 n Request PDF | On Jan 1, 2009, Alfredo Chetta and others published Restrictive Lung Disease | Find, read and cite all the research you need on ResearchGate Abstract. Unlike obstructive lung diseases, such as 0000005882 00000 n People with a restrictive lung disease have a difficult time filling their lungs with air because their lungs are restricted from fully expanding.
