Abstract：Objective An increased compression rate always delivers an inadequate depth during the cardiopulmonary resuscitation (CPR) performance.The proportion of subjects compressing at the correct rate and depth is very important to a successful CPR operation .In this study, we aimed to determine whether listening to music during CPR training increase the compliance of effective external chest compression .Methods One hundred and thirty -one residents were randomized into two groups ( music group vs .no -music group ) to perform CPR training .Participants in music group perform continuous external chest compressions on a manikin accompanied by “Radetzkymarsch” and were asked to time compressions to the musical beat , meanwhile no-music group accompanied by no music .After two weeks , the participants were retested of one minute continuous external chest compressions without listening to the music .Rates and depth of external chest compressions were delivered by the manikin . Results The average compression rates in music group were significant lower than no -music group . But the average compression depths were not significantly different between two groups .Differences in proportions of correct compression rate were significant for music ( 65%) and no -music ( 48%) groups, but there was no significant difference in proportions of correct compression depth .There was a significant negative correlation between compression rates and depths in no -music group, but not in music group.Conclusion Listening to music significantly increases the compliance of effective external chest compression .Because of the convenient use and rapid operation , we think listening to music during CPR training would prompt the effective delivery of external chest compression at an appropriate rate and depth.
