    INPUT: The patient is intubated . The endotracheal tube terminates approximately 3 .5 cm above the carina . An orogastric tube courses into the stomach . A right internal jugular central venous catheter terminates in the upper superior vena cava . The cardiac , mediastinal and hilar contours are probably unchanged allowing for differences in technique . There is new mild to moderate central vascular hilar congestion and , at the left lung base , volume loss with a new pleural effusion probably including atelectasis . Known carcinoma is not visible on this study .
    OUTPUT:
    
Findings suggest mild to moderate pulmonary edema . Volume loss and opacification of the left lung base , probably due to a pleural effusion with atelectasis .
