If after choking, the person is conscious and there is no sign of complete airway obstruction and insufficient gas exchange, coughing is the preferred method to exclude foreign bodies from the airway. First of all, you should remain calm and avoid overstressing and hyperventilation leading to rice particles into the deeper airways, then inhale slowly and cough hard, which can be repeated several times until the rice particles are discharged. If you still can’t expel it, you can go to the ear, nose and throat department of a regular hospital for further consultation and ask for professional doctor’s help. For patients with airway obstruction or insufficient gas exchange, the Heimlich abdominal shock method can be used to expel the meal.
