Disease shown in this PFT is best characterized by
Restrictive disorders are characterized by low lung volumes. Diffusing capacity (DLCO) may or not be decreased in pulmonary fibrosis), a type of restrictive disease. A decrease in the forced expi­ratory volume in one second-forced vital ca­pacity (FEV1/FVC) ratio is the hallmark of obstructive, not restrictive, disease & capacity (VC) and airway resistance (Raw) are de­creased in-restrictive lung disorders.
