According to today's article the timing for the Bee Gee's popular disco song, "Stayin' Alive" is almost exactly the right timing to use when chest compressions giving someone CPR.
"Stayin' Alive" is good because "...Everybody's heard it at some point in their life. People know the song and can keep it in their head."
The article does not mention if you need to inhale helium to make your voice go as high as the Bee Gee's lead singer when giving the mouth-to-mouth portion of CPR.
BTW: Don't use the version played in Airplane (the movie). It is over 10 beats per minute faster than the record version.
