Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip is low lying , terminating approximately 1 .8 cm from the carina , and should be withdrawn . Orogastric tube is seen with tip appearing to terminate in the distal esophagus , and should be advanced for optimal positioning . Lung volumes remain low . The heart size remains moderately enlarged . There is unchanged mediastinal widening , likely related to low lung volumes . There is worsening pulmonary edema , now mild to moderate in extent with probable small bilateral pleural effusions . Focal opacity is seen within the periphery of the right mid - to - upper lung field , could reflect an infectious process . No pneumothorax is clearly evident .
    OUTPUT:
    
1 . Low - lying endotracheal tube , terminating approximately 1 .8 cm from the carina , and should be withdrawn slightly . 2 . Orogastric tube tip appears to terminate within the distal esophagus and should be advanced . 3 . Interval worsening of mild to moderate pulmonary edema with probable small bilateral pleural effusions . Continued opacification within the peripheral right upper - to - mid lung field .
