    INPUT: Semi-upright portable chest radiograph demonstrates an endotracheal tube with its tip located at least 3 .5 cm from the level of the carina , right upper extremity PICC with its tip in the mid SVC , and an NG tube , the tip of which is not seen below the level of the diaphragm . A dual - lumen hemodialysis catheter tip projects in the lower SVC . There is little change in low lung volumes , with linear atelectasis of the right lung base and improvement in retrocardiac atelectasis , which remains large . A left lower lobe nodular opacity likely reflects focal residual atelectasis . Surgical clips project over the gallbladder fossa . There is no pneumothorax , the cardiac silhouette and mediastinal contours are unchanged . There is mild edema ; pleural effusions are small if any .
    OUTPUT:
    
Unchanged low lung volumes with atelectasis , and mild edema .
