    INPUT: Left - sided central line terminates in the upper SVC . ET tube terminates appropriately approximately 3 .2 cm above the carina . Small bilateral pleural effusions are persistent . Mild cardiomegaly is stable , with prominence of the hilar and mediastinal contours , likely secondary to low lung volumes . There has been slight interval increase in mild bibasilar atelectasis . An enteric tube extends below the diaphragm with the tip in the body of the stomach . There is no evidence of pneumothorax .
    OUTPUT:
    
Lower lung volumes compared to the prior exam resulting in an increase in mild bibasilar atelectasis . ET tube terminates approximately 3 .2 cm above the carina .
