    INPUT: Endotracheal tube tip terminates approximately 7 cm from the carina , in standard position . An electronic device is seen projecting over the aortic arch and main pulmonary artery . The heart is top normal in size with left ventricular predominance . There is no pulmonary vascular congestion . Streaky opacity in the left lung base with mild tenting of the diaphragm suggests atelectasis with volume loss . Blunting of the costophrenic angles bilaterally likely reflects the presence of small bilateral pleural effusions . No pneumothorax is identified . There are no acute osseous abnormalities .
    OUTPUT:
    
Endotracheal tube tip in standard position . Retrocardiac opacity likely reflects atelectasis . Infection is not completely excluded . Small bilateral pleural effusions .
