    INPUT: ET tube present , tip approximately 7 .5 cm above the carina , at the mid clavicular heads . NG tube present , tip beneath diaphragm over stomach . Right IJ central line tip over mid SVC . No pneumothorax detected . Compared to the prior film , the cardiomediastinal silhouette is unchanged . The degree of engorgement and alveolar opacity has improved . However , this appearance is likely accentuated by differences in technique between the 2 films . Allowing for this , there is considerable residual interstitial and some basilar alveolar edema . No gross effusion . Bibasilar atelectasis also present .
    OUTPUT:
    
Interval improvement in CHF findings , though there continues to be interstitial edema and some areas of alveolar edema . No gross effusions . Bibasilar atelectasis .
