We have http://lifeflight.org in the Rocky Mountain West. $85 a year. I wish they would expand into ground service in my area so I didn't have to worry about ambulance bills.
I was curious since I'd never seen that thing, so I watched the video: that looks useful only if you have someone to apply it to you. Seems like there'd be a market for an automatic one where all you have to do is push a button and then smash it into your face.
Maybe pick up a personal anti choking device (https://www.amazon.com/anti-choking-device/s?k=anti+choking+...) as well.
