Following are true about COPD, except
COPD is an obstructive lung disease. Obstructive diseases have reduced FEV1, FVC and reduced FEV1/FVC. Flow rates like MEFR (Maximal Expiratory Flow Rate ) are also reduced. 
Due to air-trapping, the residual volume is increased. 
Reduction in DLco is seen interstitial lung diseases or pneumonias, not in COPD . 
DLco may be reduced in Emphysema due to alveolar damage.
Reduced FEV1
Increased Residual Volume
Decreased Diffusion capacity (DLco)
Decreased Maximal Expiratory Flow Rate (MEFR)
