LifeVac is a non-powered, non-invasive, 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. LifeVac has been designed to be easy to use in an emergency. The LifeVac Home Kit is the perfect addition to your household safety.
