Following the beat of some songs have been recommended to help people hit the right number of chest compressions, but the depth of each push is wrong. A new study calls for an end to this field.
Following the beat of that song has been recommended in the past to help people perform the correct number of chest compressions each minute. But this can lead to inadequate compressions that are too shallow.
Researchers argue that better alternatives are available and that research into music’s role in CPR should come to an end. The BBC reports.
Cardiopulmonary (or mouth-to-mouth) resuscitation is thought to triple the survival rates of people when their hearts stop beating. That’s with about a 2-inch compression at a rate of 100-120 compressions per minute.
For Americans, the Bee Gees’s Stayin’ Alive – which contains 103 beats per minute – was recommended. In the UK, it was Nellie the Elephant.
While there were increases in the number of people getting the right rate, there were drops in those hitting the correct depth, according to a 2009 study.
This new study investigates Achy Breaky Heart (by Billy Ray Cyrus) and Disco Science (by Mirwais). More than a third of compressions were still too shallow.
The study authors are unconvinced that music provides any benefit in improving the quality of CPR compared with a metronome or audible feedback, suggesting that “this interesting but unproductive area of resuscitation research should be discontinued.”
However, "anything that encouraged people to intervene was a good thing,” says study author Malcolm Woollard of Coventry University in the UK. "Any form of CPR is better than none at all.”
The technique could still be useful if paired with devices that can sense the pressure and rate of chest compressions, even some smartphones nowadays.
The new work was published in Emergency Medicine Journal last week.

That is indeed the best fix that comes to mind. Their evidently shallow (npi) investigation makes no mention of the efficacity of using music vs. having no devices at all to pace the compressions. Further, they used neither of the songs that were mentioned as recommended for this use, but seemingly picked musical selections based more on thematic titles. I have to question the credentials (and intelligence, and motives) of researchers calling for ANY ethically sound research to be discontinued based simply on their dislike of the methods being investigated. Perhaps we should mandate that henceforth all heart stoppage must occur in a conservatory of music?
If that is the results of "their" study then maybe they should review "their" study to determine what needs to be done to correct the flaw in the application. Better yet, I will save them the time. Trainers, emphasis on depth of compression is vital to the proper training of cpr students. No one is going to carry a metronome in their back pocket, associating the rate of chest compressions to a particular song allows for a built in metronome. Focus on the training, that is the fix.
