Effectiveness of different music tempos in guiding cardiopulmonary resuscitation training.

Abstract

This study aimed to compare the effectiveness of different musical tempos on the quality of cardiopulmonary resuscitation (CPR). A total of 150 untrained intern doctors and nurses were randomly assigned to three groups: No Music (NM group), Slow tempo Music (AS group), and Fast tempo Music (BR group), with 50 participants in each group. Following the theoretical study of CPR, three groups of trainees were assessed. Trainees in the NM group performed CPR without any music, whereas the AS group practiced with the background music of "All Star" (104 bpm) and the BR group utilized "Bad Romance" (119 bpm) during their assessments. Outcome measures included overall compression scores, compression rate, compression depth, rate of adequate compression depth and rate of adequate chest recoil. The overall compression score for the AS group was 86.0 (interquartile range [IQR] 59.0-93.0), which was significantly higher than the BR group's score of 57.0 (IQR 40.0-84.0) and the NM group's score of 54.0 (IQR 39.5-72.0) (P < .05). The AS group demonstrated significant differences in both compression rate and depth compared to the BR and NM groups (P < .05). However, there were no significant differences in the rate of adequate chest recoil among the three groups (P > .05). In CPR training for untrained medical students, using music with a tempo of 104 bpm enhances CPR effectiveness. However, it does not increase the rate of adequate chest recoil.
