Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube terminates 3 .5 cm from the carina . Enteric tube and side port are within the stomach . Lung volumes are low . This accentuates the size of the cardiac silhouette which appears mildly enlarged . Apparent widening of the superior mediastinal contour also is likely due to low lung volumes . There is crowding of the bronchovascular structures without overt pulmonary edema . Patchy and linear opacities in the lung bases likely reflect areas of atelectasis . No large pleural effusion or pneumothorax is present . No acute osseous abnormalities are visualized .
    OUTPUT:
    
1 . Standard positioning of the endotracheal and enteric tubes . 2 . Low lung volumes with bibasilar atelectasis .
