Approximately 90% of those suffering an out-of-hospital cardiac arrest will die. (but see the figures from @mloxton ) For each minute of delay in CPR/AED survival chances decrease by 10%. Speed is of the essence.

The AED will talk you through what to do, and it will only administer a shock if the person has a shockable rhythm.

And if you are on your own - GET HELP, there is nothing as lonely or intimidating as attempting CPR/defib on your own.
