Spent last Monday night at my gun club getting rectified in CPR. It has been a good 10 or 15 years since I took the class. Now it covers the use of AEDs too.
Folks I cant say it enough. Go learn CPR. It was about a 3 hour class and it could save someones life. They tell us that for every minute a person is down without CPR their chances drop 7%-10%. . . That is quick.
We like to say we are the first responders, we are the ones who call the fire or police for help. Well if you really want to be useful as a first responder you should know CPR and First Aid. (going for my certs in a week or so for First Aid) The life you save may be a family member.
And once you go, get the stuff you need to be ready. You can get breathing shields and such for small money on Amazon. Some will even come in a pouch you can hang on a key chain so you always have it. If you go camping or hunting it is even more important to have a good First Aid kit and training to use it when help is not a simple quick 911 call away.
As an NRA instructor I felt it was important to take the course, but I would have taken it instructor or not. This is a critical skill that is easy to pick up. Everyone should be trained to save a life.
