Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present approximately 6 .2 cm above the Carina . An NG tube is present , tip extending beneath diaphragm , off the film . A left subclavian central line is present , tip over mid SVC . 2 left - sided chest tubes are present , 1 with a pigtail configuration . The cardiomediastinal silhouette is grossly unchanged . Again seen are is upper zone redistribution , interstitial edema , and mild vascular blurring , consistent with mild CHF and similar to the prior film . There is patchy opacity at both lung bases . There is also retrocardiac density , consistent with left lower lobe collapse and or consolidation . Triangular opacity at the right lung base is more pronounced and could represent subsegmental atelectasis minimally displaced left posterior sixth rib fracture again noted . No gross pneumothorax , though a subtle pneumothorax might not be apparent on this film . Prominent subcutaneous emphysema along the left chest wall an overlying pectoralis muscle . A smaller amount of subcutaneous emphysema is seen along the right chest inferiorly and in the right pectoralis muscle . Multiple bilateral rib fractures , left clavicular fracture , an left scapular fracture are again noted .
    OUTPUT:
    
No definite pneumothorax detected , though small pneumothorax might be obscured by overlying tubing and subcutaneous emphysema . More pronounced triangular opacity at the right base --___ subsegmental atelectasis . Otherwise , doubt significant interval change .
