Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided PICC terminates in the distal SVC . The patient is intubated , the endotracheal tube is positioned 4 cm above the level of the carina . A nasogastric tube is in - situ , the tip terminates below the diaphragm . Lung volumes are slightly low resulting crowding of the bronchovascular structures . Mild prominence of the interstitial markings and bilateral hila is likely related to this . No frank pulmonary edema . The cardiomediastinal contour is unchanged compared to the prior study . No consolidation or pneumothorax .
    OUTPUT:
    
Low lung volumes . No acute cardiopulmonary process seen .
