Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal supine view of the chest was obtained . Detailed evaluation is limited by overlying trauma board and numerous overlying external medical devices . An endotracheal tube terminates in the proximal left main stem bronchus . The right lung is atelectatic with an elevated right hemidiaphragm , likely related to ET tube position . Low lung volumes exaggerate the heart size . No focal consolidation , large pleural effusion , or pneumothorax . Multiple likely acute bilateral rib fractures .
    OUTPUT:
    
1 . Endotracheal tube terminates in proximal left main bronchus . ET tube should be withdrawn at least 4 cm for optimal positioning . Right lung atelectasis and elevation of right hemidiaphragm are likely related to ETT position . 2 . Multiple bilateral rib fractures , likely related to resuscitation . Findings were paged to Dr . ___ at the time of study , which was the time of discovery , with subsequent reply page stating that the patient had expired due to unrelated causes .
