    INPUT: Portable frontal semi-erect chest radiograph demonstrates an endotracheal tube terminating in the mid thoracic trachea . Upper sternal wires are fractured and new plating from both sides of what looks like sternal dehiscence . There are low lung volumes , with exaggeration of the cardiac silhouette and bronchovascular crowding . Even allowing for this , there is at least moderate cardiomegaly . Diffuse bilateral opacities consistent with mild pulmonary edema . No focal consolidation or appreciable pleural effusion or pneumothorax is visualized .
    OUTPUT:
