    INPUT: A portable AP radiograph of the chest depicts a new orogastric tube coursing through the esophagus and terminating within the stomach . The endotracheal tube is unchanged in position , no less than 3 .8 cm above the carina . A right internal jugular introduction sheath terminates in the upper SVC . There is persistent mild cardiomegaly and mediastinal widening . The left retrocardiac opacity has not markedly changed from the most recent study approximately six hours ago . Atelectasis at the right base has improved somewhat . The lungs are otherwise clear , and the pulmonary vascularity is normal , without edema . There is no pneumothorax or large pleural effusion .
    OUTPUT:
    
1 . Orogastric tube terminates within the stomach . 2 . Considerable left lower lobe atelectasis persists . In the setting of infectious symptoms , pneumonia in this region can not be excluded .
