restrictive disease,air has pb in coming in...so TLC decreased,RV is decreased,tidal volume should also decrease ,FEV1 increases as although less air comes in but these small volumes efficeintly go out. ___________________ I CAN DO IT.

FEV can be normal in restrictive lung diseases such as pulmonary fibrosis, or increased as in asbestosis, etc, since there is no airway obstruction.

I believe the ratio of FEV1/FVC can be normal or increased in patients with Restrictive PD but FEV1 and FVC separately are both decreased.

Yes, FEV decreases. But, the FEV/ FVC IS increased or normal.
