Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest was obtained . The patient 's chin obscures the lung apices , particularly the right lung apex , obscuring the view . There are low lung volumes . No focal consolidation , pleural effusion , or evidence of pneumothorax is seen . The cardiac and mediastinal silhouettes are stable . The bones are diffusely osteopenic , making evaluation for subtle fracture suboptimal .
    OUTPUT:
    
No definite acute fracture is seen , although if concern for rib fracture is high , suggest rib series .
