    INPUT: A tracheostomy is in - situ , unchanged in appearance compared to the prior study . Lung volumes are low , this limits assessment . A right - sided PICC terminates in the mid to distal SVC . A ventriculoperitoneal shunt is incompletely visualized . An IVC filter is seen in the upper abdomen . A gastrostomy tube is incompletely visualized . Even allowing for the projection , the heart is enlarged . Bilateral airspace opacities are again seen . This is more confluent in the right upper lobe than on the prior study . Appearances remain concerning for infection .
    OUTPUT:
    
Airspace opacity now appears more confluent in the right upper lobe . Bilateral airspace opacities persist . Otherwise , no significant interval change .
