Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single semi-erect portable view of the chest was obtained . The cardiac and mediastinal silhouettes are grossly unremarkable . Endotracheal tube terminates approximately 4 cm below the level of the carina . Enteric tube courses below the level of the diaphragm , terminating in the left upper quadrant in the expected location of the stomach . There are low lung volumes . Subtle patchy right upper lobe opacity may be due to low lung volumes , though underlying contusion is not excluded . No large pleural effusion is seen . There is no evidence of pneumothorax . There appears to be a mildly displaced fracture of the lateral right third rib .
    OUTPUT:
    
1 . Endotracheal and nasogastric tubes appear in appropriate position . 2 . Low lung volumes accentuate the bronchovascular markings . Subtle hazy opacity over the right upper lung may be due to low lung volumes , although underlying pulmonary contusion is not excluded . Lateral third right rib fracture .
