Symptoms Foreign body stuck in the throat is commonly seen in children who laugh, play or cry while eating or holding a foreign body in their mouth. As the foreign body is embedded in the voice box or falls into the trachea, it can cause choking or severe breathing difficulties, or even respiratory and cardiac arrest. First aid measures Never pat the back! Learn the “Heimlich maneuver”! This method is suitable for children over 2 years old. The specific steps are: 1. Stand behind the child. 2, with two arms around the patient’s waist, one hand clenched fist against the lower edge of the rib cage and navel, the other hand holding the fist. 3.Tighten both arms and quickly press the child’s chest inward and upward, forming a percussive airflow to flush out the hard pieces of food blocking the trachea and throat. 4.Continue to squeeze and press several times until the blockage of the trachea is lifted and the foreign body is discharged.
