All the preparation in the world may help reduce choking incidents, but choking prevention methods are not always effective. In those cases, it is important that you know what to do. This starts with recognizing the signs of trouble, acting quickly to restore breathing and prevent or minimize damage to the brain, and knowing the steps of the Heimlich maneuver so you can dislodge the blockage. 

Learning CPR and the Heimlich maneuver can help save lives, and so can calling 9-1-1 immediately.
