    INPUT: Single AP upright portable view of the chest was obtained . There are relatively low lung volumes , which accentuate the bronchovascular markings , particularly at the lung bases . Given this , no focal consolidation is seen . There is no large pleural effusion or evidence of pneumothorax . The cardiac and mediastinal silhouettes are unremarkable . No overt pulmonary edema is seen .
    OUTPUT:
    
Low lung volumes without definite acute cardiopulmonary process . Dedicated PA and lateral views of the chest would be helpful for further evaluation if patient able .
