Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An enteric tube courses inferiorly in the midline , with distal side port seen approximately 3 .5 cm distal to the GE junction , with tip projecting over the approximate location of the gastric body in the left upper abdominal quadrant . There are low lung volumes and a suboptimal inspiratory effort . There is at least moderate cardiomegaly . There are aortic arch calcifications . The bilateral hila are within normal limits . There is bibasilar atelectasis . There may be mild pulmonary vascular congestion . There is no pleural effusion or pneumothorax . There is no focal lung consolidation .
    OUTPUT:
    
1 . Enteric tube in grossly appropriate location , with tip likely in the gastric body . 2 . Moderate cardiomegaly and likely some component of pulmonary vascular congestion . No focal lung consolidation . 3 . Bibasilar opacities likely reflect relaxation atelectasis in the setting of low lung volumes .
