This simple device- Lifevac – claims to be able to save a choking person when the Heimlich Maneuver doesn’t work.
The device uses a patented air release and vacuum technology to pull a lodged item from a person’s windpipe. It is simple to use-according to the product’s website, you can even use it on yourself.
If it works, so many children, adults and elderly will be saved by keeping one of these in every school, restaurant, business and home.
