    INPUT: A portable frontal chest radiograph again demonstrates a right chest wall port with the catheter terminating in the low SVC . Bilateral surgical clips are again noted , reflecting prior breast surgery . Lung volumes are slightly lower compared to prior exam , accentuating cardiac size and bronchovascular crowding . Allowing for this , the cardiomediastinal silhouette is normal and there is no focal consolidation , appreciable pleural effusion , or pneumothorax . The visualized upper abdomen is unremarkable .
    OUTPUT:
    
No acute cardiopulmonary process . Slightly low lung volumes .
