Congratulations, it's a wonderful feeling. I'm a relatively new Call Taker with the South Australian Ambulance Service, and I had my first 'successful' CPR instruction over the phone the other night. I got a call from one of the two crews that attended wanting to pass on thanks from the wife (who I was instructing to do CPR) for the help, and from themselves, as it kept him close enough to alive for them to be able to pump him full of adrenaline and electricity, to keep him alive until the hospital. Unfortunately his outlook won't be that good, as he had undergone a triple bypass the week before, but at least he should be able to say goodbye :(
