Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube is low lying , at the level of the carina and approaching the right mainstem bronchus . Enteric tube tip is within the stomach . Lung volumes are low . Mild enlargement of cardiac silhouette is demonstrated . The aorta appears tortuous . Pulmonary vasculature is not engorged . Apparent widening of the superior mediastinum is likely due to supine positioning and low lung volumes . Linear and streaky opacities in the lung bases most likely reflect areas of atelectasis . Aspiration can not be completely excluded . No large pleural effusion or pneumothorax is detected on this supine exam . The stomach demonstrates mild gaseous distention .
    OUTPUT:
    
1 . Endotracheal tube tip at the carina , approaching the right mainstem bronchus orifice and should be retracted by approximately 5 cm . 2 . Enteric tube tip within the stomach . 3 . Streaky and linear opacities in the lung bases , likely atelectasis though aspiration can not be completely excluded .
