If your baby is choking, you can use the Heimlich maneuver to provide first aid and call 120 emergency immediately. Babies who are choking are usually having their airways blocked by a foreign body, which usually manifests itself as acute airway obstruction and respiratory distress, and can be treated with the Heimlich maneuver. For infants one year old or younger, the operator usually uses the left forearm to pass through the infant’s chest, then supports the infant’s head and neck with the hand, and then lets the infant face down. It is important to note that the head is lower than the chest and abdomen, and then the baby’s back is tapped firmly with the root of the right palm so that there is constrictive pressure on the chest, which causes outward impact on the airway and promotes the expulsion of foreign bodies from the airway. In the case of babies over one year of age, chest impingement or abdominal impingement can also be used to achieve the above effect. For conscious children, the rescuer stands behind the child’s side and wraps both arms behind him or her, placing them midway between the navel and the ribs. The rescuer makes a fist with one hand and wraps the other around the fist, and rapidly and forcefully pushes inward and upward until the foreign body is expelled. After the first aid, even if the foreign body has been eliminated, the baby should be examined in time to see if there are any other injuries.
