The ActFast training vest is an excellent aid to teach the proper Abdominal Thrust Manuever, commonly known as the Heimlich Manuever. CPR instructors, hospitals, EMS, fire departments, or any other safety organization will find this a very effective teaching tool.
It provides students with instant feedback on proper placement of their hands and technique for the upward thrust needed to dislodge obstructions in the victim's airway. It can even be used to teach self rescue.
