Actually Sapph you're not far off with the song for performing CPR properly! The one that is typically used is Staying Alive by the Bee Gees! I've actually been doing CPR (for real) with a doctor singing the song while the line of us did compressions!
Angela, I know Stayin' Alive is much used. In fact all five songs I brought in this series, including this one is taken from a Spotify playlist of 40 songs the NewYork-Presbyterian has put together, allowing each of us to find a song we can remember should we ever get into a situation where we need to give CPR. :-)
