Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP erect portable view of the chest was obtained . The patient is rotated to the right and the chin overlies the right upper lung . Radiology technologist indicated best image possible , the patient nonresponsive and unable to move chin up . The patient 's chin overlies the right upper lobe , obscuring the view . There are low lung volumes which accentuate the bronchovascular markings . Low lung volumes also likely accentuate the mediastinum , which appears widened but likely unchanged compared to prior radiographs . Difficult to exclude trace bilateral pleural effusions . No focal consolidation is seen .
    OUTPUT:
    
Suboptimal study due to low lung volumes with the patient 's chin overlying the right upper lobe . Low lung volumes accentuate the bronchovascular markings and likely cardiomediastinal silhouette . Suggest repeat radiographs with better positioning / inspiratory effort when / if the patient is able .
