Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a poor inspiratory effort and low lung volumes . There has been interval placement of a right subclavian stent . The cardiomediastinal silhouettes are unchanged as compared to prior radiograph . Again , there is the appearance of cardiomegaly , however this is unreliable given the extremely low lung volumes . There is seen a right lower lobe consolidation with an air bronchogram which was not seen on prior radiograph , but which likely corresponds to the area of right lung consolidation thought to be pneumonia which is mentioned in the history . There is right minimal intrafissural fluid in the minor fissure . There is no pneumothorax or effusion .
    OUTPUT:
    
Low lung volumes . Known right lower lobe pneumonia . No other acute cardiopulmonary abnormalities .
