Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present --___ tip lies in satisfactory position approximately 3 .2 cm above the carina . An NG tube is present --___ tip overlies the gastric fundus . A left subclavian central line is present --___ tip lies at the expected site of confluence with the proximal SVC . No pneumothorax is detected . There is background hyperinflation suggestive of COPD . There is probable mild cardiomegaly , not significantly changed . There is increased retrocardiac density consistent with left lower lobe collapse and / or consolidation . There is probable left - sided volume loss , as the cardiomediastinal silhouette is shifted to the left . There is upper zone redistribution , but no overt CHF . There is atelectasis at the right lung base . Possibility of changes due to aspiration would be difficult to exclude in this setting . No gross effusion . No pneumothorax detected . Density seen in the left upper zone are probably related to overlying materials .
    OUTPUT:
    
1 . ET tube tip 3 .2 cm above the carina . 2 . NG tube tip over gastric fundus . 3 . Left lower lobe collapse and / or consolidation , with apparent leftward shift of the mediastinum . 4 . Patchy opacity right base , likely atelectasis . However , it is there clinical concern for aspiration ?
