FEV, is preserved and FVC is decreased so FEV IFTC is increased The hallmark of restrictive lung diseases is a decrease in lung volumes primarily TLC and V.C. FVC is decreased-Harrison Compliance decreases in restrictive lung disease. Compliance is usually unaffected in obstructive lung diseases except in emphysema where it is increased.
