    INPUT: A small amount of aerated lung is seen in the left chest laterally . A few air bronchograms are visualize . Otherwise , the left chest is opacified . There continues to be mediastinal shift to the left indicating that the left lung is at least partially collapsed . The more distal trachea and proximal left mainstem bronchus are now aerated , which is improved compared to the prior study however , the right mainstem bronchus is poorly visualized as are the more distal left - sided airways . There continues to be hazy opacity projecting over the right lung . Is unclear how much of this is due to patient 's soft tissue or if there is an effusion layering posteriorly or and alveolar infiltrate on the right .
    OUTPUT:
    
A small amount of improved aeration on the left with continued near complete opacification of the left hemi thorax
