    INPUT: Endotracheal tube terminates 4 cm above the carina . Nasogastric tube courses below the diaphragm and inferiorly beyond the field of view . Lung volumes are low , with bibasilar atelectasis . Moderate cardiomegaly persists , with a tortuous and unfolded aorta and probable right aortic arch . There is probable central venous congestion , pulmonary vascular plethora , and small bilateral pleural effusions .
    OUTPUT:
    
1 . Endotracheal tube in standard position . 2 . Nasogastric tube courses towards the right abdomen , which may reflect gaseous distention versus patient rotation . 3 . Mild heart failure . Right aortic arch 4 . Low lung volumes with bibasilar atelectasis .
