Lateral cervical spine x-ray showing King LT-D Airway not placed correctly with tip folded up against the larynx. (click to enlarge)
As you can from the cross table radiograph, the distal tip of the King Airway has wedged itself in the pharynx and folded against itself. It is not seated properly against the hypopharynx. While this was providing ventilation, it also stented open the esophagus leading to a large amount of gastric insufflation.
