Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal view of the chest demonstrates ET tube terminating along the upper margin of the clavicles , located no less than 3 .5 cm above the carina , appropriate in location . A left basal approach pleural catheter traverses medially with tip terminating at the margin of the mediastinum . The lung volumes remain low , with mildly increased bibasal atelectasis since two days ago , but stable since one day prior . Dense retrocardiac opacities persist , compatible with left lower lobe collapse . A small left pleural effusion is unchanged . There is no evidence of pneumothorax . Mild bronchovascular crowding is accentuated by low lung volume . The heart is top normal in size . The mediastinal and hilar contours are within normal limits .
    OUTPUT:
    
1 . New small right pleural effusion since one day prior . 2 . Stable left lower lobe collapse . 3 . Similar right basilar atelectasis since yesterday but increased since two days prior .
