Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An overlying trauma board and support devices obscure the radiograph . The endotracheal tube ends 7 cm above the carina . A right internal jugular line ends in the upper superior vena cava . The cardiac silhouette is markedly enlarged . Mild widening of the mediastinum is likely positional . There is no right pleural effusion . The left costophrenic angle is not included on the film . Diffused increased opacity in the left lung may be due to positioning or a layering pleural effusion . There are right - sided rib fractures . There are no focal opacities . No pneumothorax identified . The cardiac and mediastinal contours are stable .
    OUTPUT:
    
1 . The endotracheal tube ends 7 cm above the carina and could be advanced . 2 . Multiple right - sided rib fractures are of undetermined chronicity . No definite pneumothorax . Repeat radiograph could be obtained once the patient is stable . 3 . Enlargement of the cardiac silhouette could represent underlying cardiomyopathy or a pericardial effusion . 4 . Possible small layering left pleural effusion
