The LifeVac is a non-invasive, non-powered, portable ACD (Airway Clearance Device) developed to remove an object/food from a victim with an airway obstruction when standard choking protocol has been followed without success. It is designed with a patented one-way valve that prevents air from pushing the object/food 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 3 times greater than the highest recorded choke pressure.
