Choking on saliva usually results in a stressful coughing reaction and a violent cough, which can be helped by patting the patient on the back to see if the saliva can be coughed up. If not, then the Heimlich maneuver can be used, which is a special treatment for acute obstruction of the airway by a foreign body. It usually involves rapid inward and upward impact on the patient’s upper abdomen, causing the diaphragm to lift up, so that there is a sudden contraction pressure in the thoracic cavity, thus causing an impact force on the airway and shocking the foreign body out toward the mouth. If by this method or unsuccessful, then to avoid their aspiration pneumonia, or to avoid their breathing difficulties, they should go to the hospital for bronchoscopy to suck out the saliva.
