This is a case of a misplaced nasogastric tube, which needs to be urgently re-sited. Feeding through a nasogastric tube situated in the airway will cause significant morbidity, and potentially death.
The weighted tip of the nasogastric tube should project below the left hemi-diaphragm - a minimum of 5-10 cm beyond the gastro-esophageal junction. Any side holes should also be positioned distal to the gastro-esophageal junction.
