If you're delivering CPR and are wondering at what tempo you should be doing the chest compressions, just run the song "Stayin' Alive" through your head, (or instruct the DJ at the club you're in to play it) since it runs at the right speed.

I suppose this assumes that your mental mp3 player will run at the right speed when you're in a life-or-death situation... that could be a possible direction for future research.
