Purpose: An adequate chest compression rate during CPR is associated with improved hemodynamics and primary survival rate. The purpose of this study was to compare performance based measures of chest compression (CC), including compression rate and depth, from two versions of a CPR course: Instructor-led (IL) training, and the same IL training but augmented with rhythmic music.
Methods: Ninety-one medical students having completed the BLS provider course, 4 months prior, participated in
CPR quality improvement education. Participants performed 2 min of CC on a manikin utilizing an accelerometer-based system that measured both rate (CC/min) and depth (cm) of CC. CC parameters were evaluated three times: prior to the education, immediately after the education, and again after four months. CPR quality was analyzed using the manikin/accelerometer system. The primary outcome measures included: (1) compression rate, (2) compression depth, (3) percentage of compressions performed with adequate rate, (4) percentage of compressions performed with adequate depth, (5) absolute deviation from 100 in terms of compression rate, and (6) each 2 minute test was divided into 4 30 second sections, and any rate differences between the 4 sections were assessed. For the augmented IL study, popular music with a tempo of 100 beats per minute was utilized.
Results: There were no differences in CC rate and depth between the two IL trainings. However, students offered IL training augmented with musical rhythm performed CC with a higher percentage of adequate rate and depth. They also
had less absolute deviation and variation of CC rate difference between the four, 30 second sections, than students
instructed without the use of rhythmic music.
Conclusion: Students receiving IL training augmented with music performed adequate, standardized CC with a steadier rate than those who received IL training without the benefit of music. This result provides evidence to support the
use of rhythmic music in improving BLS education results.
