<prompt> What is true for restrictive lung disease?FEV1FVC decreased, compliance normalFEV1FVC increased, compliance increasedFEV1FVC decreased, compliance increasedFEV1FVC increased, compliance decreased  <response>: In Restrictive lung disease, parenchymal involvement will lead to pulmonary fibrosis and hence it will be difficult to inflate the lung leading to the reduction in lung compliance. The FEV1 FVC ratio is increased in restrictive lung disease because the numerator and denominator in the ratio are both reduced in restrictive lung disease, with FVC decreasing dispropoionately.
