Evaluating Auditory Feedback for Accurate Compression Rates

Abstract

...In this study, candidates were screened for eligibility and randomly assigned to one of four groups: a control group receiving no auditory feedback, a metronome group set to exactly 110 beats per minute (BPM), a Music A group using music with an average tempo of 104 BPM, and a Music B group using music with an average tempo of 114 BPM. These groups were specifically designed to evaluate not only the effectiveness of auditory feedback but also whether the type of auditory feedback influenced performance. Music tracks were selected based on their tempo, recognizability, and prior association with CPR training materials endorsed by the American Heart Association³. A Laerdal QCPR manikin was used to evaluate the chest compression rate for each group.

The results demonstrated that auditory feedback made no clinically significant difference in the ability of professional rescuers to achieve an appropriate chest compression rate. Candidates in all three audio feedback groups maintained standard deviations that kept them within the currently recommended compression rates but did not show statistically significant improvement compared to the control group.

Based on these findings, these findings suggest that routine use of auditory feedback during CPR by professional rescuers may not be warranted. This study demonstrated no significant impact of auditory feedback on chest compression rates. Additionally, the potential for increased background noise associated with auditory cues may warrant consideration, as such interference could hinder communication during resuscitation, an element previously linked to medical errors in high-stakes clinical environments.The implementation of crew resource management principles, including maintaining a sterile cockpit environment during critical phases, has consistently demonstrated a reduction in medical errors during critical medical interventions.⁴
