When a small baby chokes on a foreign body, there is usually an acute obstruction of the airway and breathing difficulties. This situation can be treated with the Heimlich maneuver, which is currently recognized worldwide as an effective method of treating acute airway obstruction by foreign bodies. If the infant is one year old or younger, the operator usually holds the infant’s chest with the forearm of the left hand, then let the infant face down, it must be noted that the head should be lower than the chest and abdomen, and then the right hand pats the back of the child, so that the thorax has a contraction pressure, so that the airway has an outward impact, which can impact the foreign body blocked in the airway, so that it can be discharged from the mouth and then vomited out. In the case of older infants, the chest shock method or abdominal shock method can also be used to achieve the above effect. In any case, it is necessary to ensure that the trachea is open, avoid choking, and go to the hospital for imaging or bronchoscopy in time to remove the foreign body.
