    INPUT: Lung volumes are low exaggerating prominence of the cardiac silhouette and vascular crowding , although compared to prior exam there is haziness of the pulmonary vasculature suggestive of a component of pulmonary edema . Low lung volumes are associated with bibasilar atelectasis . A tracheostomy tube is in proper positioning . A right PICC is again seen with the tip terminating in the right atrium . There is no large pleural effusion or pneumothorax .
    OUTPUT:
    
Interval development of mild pulmonary edema . No focal consolidation to suggest pneumonia .
