The LifeVac is a non-powered, non-invasive, single-use-only airway clearance device developed for resuscitating a victim with an airway obstruction when current choking protocols have been followed without success. LifeVac has a one-way valve that does not allow any air to enter a choking victim on the downward motion. The duration of the suction is minimal which makes LifeVac safe and effective. LifeVac is easy to use in an obstructed airway emergency. Free replacement LifeVac when used in a choking emergency! Free online training is available.
