Chewing gum that gets stuck in the windpipe begins to show up as an irritating cough. If the jam is mild and the gum is not very large, it is usually accompanied by mild dyspnea. If the gum is large and the jam is severe, there will be severe dyspnea, resulting in cyanosis of the skin on the face and all over the body, and listening for widespread rales in both lungs, and even rales can be emitted through the larynx. In this case, consider applying the Heimlich maneuver by shocking the epigastrium inward and upward to see if the gum can be flushed out of the mouth and thus spit out. If the Heimlich maneuver is unsuccessful, then you must go to the hospital to have the gum removed with a bronchofiberscope.
