I qualified as an Emergency First Responder as part of my rescue diving course.
Definitely worth doing any kind of CPR/First Aid course - particularly for the training / constant drumming in of not acting without thinking. i.e. Don't dive in with cpr straight off, but call for an ambulance first.
And as for making things worse. if somebody's heart has stopped and he is not breathing; he's dead. You can't make anything worse by giving CPR while waiting for help.
