"Stayin' Alive" may turn out to be closer to the truth than the BeeGees might have thought when they penned the disco classic in 1977.

In study from the University of Illinois medical school, doctors and students maintained close to the ideal number of chest compressions doing cardiopulmonary resuscitation while listening to the catchy, sung-in-falsetto tune from the movie "Saturday Night Fever."

"Stayin' Alive" pulses at 103 beats per minute. The ideal rhythm for CPR is 100 compressions per minute, according to research to be presented later this month at the annual meeting of the American College of Emergency Physicians.

Properly performed CPR can triple survival rates for cardiac arrest, but many people hesitate to jump in because they don’t feel confident about maintaining the proper rhythm, according to researcher Dr. David Matlock.

Research subjects reported feeling more confident about performing CPR after the musical training, he said.
