Anesthesia : Restrictive Pulmonary Disease

Restrictive pulmonary diseases are charac-terized by decreased lung compliance.

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.
