Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Slightly rotated positioning . Tubing overlies the extreme upper right lung apex . An ET tube is present . The tip lies approximately 2 .0 cm above the carina . An OG type tube is present , tip beneath diaphragm , off film . The patient is status post sternotomy , with mediastinal clips . There is a moderately large left pleural effusion , which obscures the left heart border and left hemidiaphragm and which tracks along the left chest wall and into the left lung apex . The aortic knob is not well delineated , in part due to rotation , but also due to the left apical fluid . The cardiomediastinal silhouette remains midline . On the right , there is possible minimal upper zone redistribution . Patchy opacity at the right cardiophrenic angle is noted . No frank consolidation is identified . No effusion . No pneumothorax is detected . No displaced rib fracture is identified .
    OUTPUT:
    
1 . ET tube tip 2 .0 cm above the carina . 2 . OG tube tip beneath diaphragm , off film . 3 . Moderately large left effusion with obscuration of the aortic knob , cardiac silhouette , and left hemidiaphragm . If there is an appropriate history of trauma , this would be compatible with apical capping and would raise concern for aortic injury . 4 . Underlying left lower lobe collapse and / or consolidation . 5 . Patchy opacity in right cardiophrenic region -- question atelectasis , but early infectious infiltrate or area of aspiration can not be excluded . 6 . No significant CHF or right - sided pleural effusion . 7 . Sternotomy with mediastinal clips , consistent with prior cardiac surgery .
