    INPUT: Portable semi-supine radiograph of the chest demonstrates low lung volumes with resulting bronchovascular crowding . Slight improvement in small right pleural effusion and adjacent atelectasis . Interval collapse of the left lower lobe . No significant pleural effusion or pulmonary edema is seen . Cardiomediastinal and hilar contours are unchanged . There is no pneumothorax . Tracheostomy tube ends 1 .5 cm from the carina . Left - sided subclavian central venous line ends in the cavoatrial junction . Nasogastric tube is seen ending in the stomach . A second enteric tube is seen also ending in the stomach . Large bore right - sided internal jugular central venous line ends at the mid SVC . A right - sided midline ends in the axilla .
    OUTPUT:
    
1 . Interval collapse of the left lower lobe . 2 . A relatively long appearing tracheostomy tube ends less than 2 cm from the carina . Suggest clincal evaluation if this is optimal .
