fix the head, and place the child's arms on the first responder's thighs. Then use the palm of the other hand to hit thechild's back between the shoulder blades 4-6 times to suddenly increase the pressure in the respiratory tract,

used interchangeably with the above method if necessary. Wait until

the foreign body is expelled or the child loses consciousness. Product features:
