Restrictive Pulmonary Disease
Restrictive
pulmonary diseases are charac-terized by decreased lung compliance. Lungvolumes
are typically reduced, with preservation of normal expiratory flow rates. Thus,
both FEV1 and FVC are reduced, but the FEV 1/FVC ratio is
normal.
Restrictive
pulmonary diseases include many acute and chronic intrinsic pulmonary disorders,
as well as extrinsic (extrapulmonary) disorders involv-ing the pleura, chest
wall, diaphragm, or neuromus-cular function. Reduced lung compliance increases
the work of breathing, resulting in a characteristic rapid, but shallow,
breathing pattern. Respiratory gas exchange is usually maintained until the
disease process is advanced.
