It's a great advert and what a great tune to help remeber. I did my PSC1 just before Chrismas with the Croix Rouge and we were taught mouth to mouth but one of the things that came up was the fact that as of 2012, mouth to mouth was no longer part of the syllabus. Times have changed - they did teach us how to use a defibrilator!
Advice on how to perform CPR has changed.
Please also remember that we call 18 or 112 in France for emergency services.
