Depending on the circumstances, rice can be removed by coughing, Heimlich maneuver, or bronchoscopy. 1. Coughing up: the trachea has a protective reflex, and if rice enters the airway, coughing often occurs, and small food residues can be expelled. 2. Heimlich method: If the rice ball is relatively large, resulting in obvious respiratory difficulties, at this time, you can stand behind the patient, clench your fist, put it on the abdomen below the thorax and above the navel, and exert a little force to dislodge the foreign body through a rapid upward impact. 3. Bronchoscopic removal: If the rice into the trachea, continued to be unable to exclude and cause obvious symptoms of dyspnea, should be promptly to the hospital, by the doctor in the bronchoscopy of the foreign body out. Rice into the trachea, to take timely treatment to avoid danger, do not dispose of their own, so as not to delay the condition of the subsequent treatment difficulty.
