    INPUT: No definite interval radiographic change . Inspiratory volumes are low , similar to the prior study . Again seen are extensive opacities throughout both lungs . More confluent opacity at the right lung apex is again noted , similar to the prior study . There could be very slight interval improvement in the left mid-zone , but any differences quite minimal . The cardiomediastinal silhouette is obscured by the parenchymal findings , but not clearly changed . Again noted is a tracheostomy tube , right IJ line with tip over proximal / mid SVC and a left - sided PICC line , with tip over mid SVC .
    OUTPUT:
    
Extensive opacities in both lungs again noted . Possible minimal increased aeration in the left mid zone , but the overall pattern is quite similar to the 2 most recent films ( both from ___ ) .
