    INPUT: No prior studies are available for comparison . The film is noted . An ET tube is identified 2 .8 cm from the carina and is in adequate position . There is cardiomegaly . The mediastinum is difficult to evaluate . It appears widened , which may be due to positioning . The pulmonary vasculature appears somewhat crowded likely due to poor inspiratory effort and there are no definite pleural effusions . An NG tube is identified and is seen with its sidehole in the stomach , although the tip is not visualized .
    OUTPUT:
    
1 . ET tube in adequate position . 2 . Widening of the mediastinum is likely due to positioning . A repeat AP and lateral chest radiograph is recommended once the patient has recovered from the acute process to exclude underlying pathology such as lymphadenopathy .
