Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Study is slightly limited by patient rotation . Endotracheal tube tip terminates approximately 3 cm from the carina . Enteric tube courses below the diaphragm with tip off the inferior borders of the film . Right internal jugular central venous catheter tip is noted within the proximal right atrium . Left - sided dual - chamber pacemaker device leads terminate in the right atrium and right ventricle . Heart size is mildly enlarged . Mediastinal and hilar contours are grossly unremarkable . Lung volumes are low with crowding of the bronchovascular structures . Elevation of the right hemidiaphragm is chronic . Patchy opacities within the lung bases , more so on the right , likely reflect areas of atelectasis . No pleural effusion or pneumothorax is seen . No acute osseous abnormality is visualized .
    OUTPUT:
    
1 . Standard positioning of support lines and tubes . 2 . Low lung volumes with patchy bibasilar opacities , likely atelectasis . Early infection or aspiration is not completely excluded .
