Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable radiograph of the chest demonstrates an appropriately positioned endotracheal tube , 5 .3 cm above the carina . An orogastric tube enters the stomach , though side port appears above the gastroesophageal junction . Lung volumes are markedly low . This causes exaggeration of the cardiomediastinal contour as well as crowding of pulmonary vasculature . Bibasilar airspace opacities most likely reflect atelectasis . There is no pneumothorax or pleural effusion .
    OUTPUT:
    
Appropriately positioned endotracheal tube . Side port of orogastric tube appears just above the gastroesophageal junction and should be slightly advanced . Low lung volumes with bibasilar atelectasis .
