Total atelectasis The chest x-ray shows total atelectasis of the right lung due to mucus plugging. Notice the displacement of the mediastinum to the right. Re-aeration on follow-up chest film after treatment with a suction catheter. The mediastinum has regained its normal position. A common cause of total atelectasis of a lung is a ventilation tube that is positioned too deep and thus obstructing one of the main bronchi. #Clinical #Radiology #CXR #Total #Lung #Collapse #RadiologyAssistant
