Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube tip terminates at the thoracic inlet , approximately 5 .2 cm from the carina . An orogastric tube tip and side port are both below the diaphragm , within the stomach . The patient is status post median sternotomy and CABG . Mild to moderate cardiomegaly is demonstrated . Aortic knob calcifications are present . Diffuse alveolar opacities are noted in both lungs , most reflective of moderate to severe pulmonary edema . There are likely trace bilateral pleural effusions . No pneumothorax is seen . Retrocardiac opacity could reflect atelectasis , though aspiration or infection can not be excluded . There are no acute osseous abnormalities .
    OUTPUT:
    
1 . Standard positioning of the endotracheal and orogastric tubes . 2 . Moderate to severe pulmonary edema with probable small bilateral pleural effusions . 3 . Retrocardiac opacity may reflect compressive atelectasis though infection or aspiration can not be excluded .
