A comment on the article mentions a competitor at http://lifevac.net:

"There is another version of this type of device that has been around (FDA approved) for a couple of years now. It's called LifeVac and it has been adopted by several fire departments, schools, skilled nursing facilities and families all across the eastern seaboard as well Europe and Canada. Only costs $69.95 and even that number can come down with different promotions that are offered."
