Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A supine portable frontal chest radiograph demonstrates an endotracheal tube with the tip obscured by overlying support lines and tubes , but appears to terminate 2 .5 cm above the carina . The nasogastric tube courses below the diaphragm and off the inferior edge of the image . Metallic clips are again seen in the right axilla . Lung volumes are low , resulting in increased prominence of the cardiac silhouette and bronchovascular crowding . No definite focal consolidation is seen . There is a small left pleural effusion . No pneumothorax is identified . Free air seen under the right hemidiaphragm on the prior radiograph is not well as well appreciated on this exam .
    OUTPUT:
    
1 . Endotracheal tube terminating 2 .5 cm above the carina . 2 . Small left pleural effusion . 3 . Free air seen under the right hemidiaphragm on the prior radiograph is not as well appreciated on this exam .
