    INPUT: Single frontal view of the chest was obtained with comparison to the examination from one day previously . The endotracheal tube tip is approximately 7 cm above the carina , which seems high . Suggest advancement of the tube by approximately 3 cm . Right - sided IJ central venous catheter is present , with the tip in the upper - to - mid SVC . Left - sided IJ central venous catheter is present , with the tip in the region of the brachiocephalic vein . A feeding tube remains present , extending into the abdomen , but with the distal tip not visualized . The cardiac and mediastinal silhouettes remain enlarged but unchanged . Again there are no focal pulmonary opacities , pleural effusions , or pneumothorax . Slight increased opacity of the left hemithorax compared to the right persists . This may represent some asymmetric pulmonary edema , or a superimposed component of atelectasis . The possibility of an infection can not be excluded . There is no evidence of pneumothorax . Pleural effusion is difficult to evaluate on this supine radiograph .
    OUTPUT:
