all volumes and capacities are decreased in restrictive and increased in obstructive pulm dis. Imp to differentiate between the 2 is FEV1/FVC,
decreased in obstructive and normal or increased in restrictive disease. Interstitial pneumonia, i think, it neihther obs nor restr. I would welcome all comments on it

i too was thinking like this but then i thought that it usually resolves without any impairment. I think we should take it like this during the illness iterstitial pneumonia is restrictive but heals without residual damage. This confusion arose bcaz almost all other iterstitial lung disaeses are irreversible except RDS
