    INPUT: The patient is intubated . The endotracheal tube terminates approximately 4 cm above the carina . A right vascular introducer sheath terminates near the junction between the right internal jugular and subclavian veins . A left subclavian central venous catheter terminates in the lower superior vena cava . An orogastric tube terminates in the stomach . The cardiac , mediastinal and hilar contours appear unchanged . The aortic arch is calcified . Although the right lung appears clear , there is opacification of the left lower hemithorax suggesting , most likely , a combination of atelectasis and pleural effusion , although not specific . There is no pneumothorax .
    OUTPUT:
    
Lines , tubes , and drains as above . Opacification of the left lower hemithorax suggestive of atelectasis and perhaps pleural effusion .
