Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest demonstrate low lung volumes . Cardiac silhouette is likely accentuated by the AP technique and low lung volumes , but is proabaly mildly enlarged . Increased bibasilar opacification is most compatible with atelectasis . Blunting of the costophrenic sulci on the lateral view likely represents small bilateral pleural effusions . There is no pneumothorax . Old right rib fracture and tracheostomy tube noted .
    OUTPUT:
    
1 . Low lung volumes resulting in pulmonary vascular crowding and basilar atelectasis . 2 . Small bilateral pleural effusions . 3 . Mild cardiomegaly .
