Pulmonary function changes seen in Emphysema are A/E:-: (A) | TLC, (B) | RV, (C) | FEV1, (D) | DV/DP
Answer is D. Emphysema: Destruction of alveolar septa leads to increase in compliance (C= DV/DP) Emphysema increase airway resistance & work of breathing difficulty in exhaling air due to compression of bronchioles leads to eventual increase RV & increase TLC (barrel chest). FEV1 and FVC =reduced in emphysema.
