We've all been taught the importance of performing CPR when someone near you is in trouble, but frankly, most people still have no idea what they should do. A few critical minutes can be the difference between life and death, so having knowledge on what can be done can have a life changing impact. There are also many other first-aid scenarios that you could encounter, but again many of us just aren't prepared to deal with those either. Anyone looking to be a bit more prepared when on of life's many unexpected situations arises should look into installing the "Red Cross First Aid" app on their smartphone. The Red Cross has created a resource with lots of critical advice for many common medical situations so that you can have it in the palm of your hand whenever you are in a critical situation. The content is sotred within the app itself, so you won't need a cellular signal to look things up for many common medical situations. This, hopefully, isn't going to be an apps you will use every day, but when the time comes, it's a pretty good app to have on your phone. I posted the link to download the free apps at DataDoctors.com/radio http://www.redcross.org/mobile-apps/first-aid-app
