LifeVac is non-invasive, non-powered, portable airway clearance device that is used in a choking emergency if standard. The device uses a patented one-way valve which prevents air from pushing the obstruction downward. This creates a one-way suction to remove the obstruction and clear the airway of the victim. The negative pressure generated by the force of the suction is three times greater than the highest recorded choke pressure.
