Abstract

To evaluate the effect of a mental metronome on chest compression rate at the point of training and 10 weeks later. A prospective observational study was performed using veterinary students without training in CPR. Students received a lecture and demonstration of CPR. The "Song group" (SG) listened to "Stayin' Alive" performed by the Bee Gees and were asked to think about the tempo during chest compressions. The "No Song group" (NSG) was given no guidance on achieving the correct chest compression rate. After the demonstration, both groups were instructed to perform chest compressions at a rate of 100 compressions per minute on a canine manikin, and the actual rate of compressions administered was calculated (Assessment 1). This task was repeated approximately 10 weeks later (Assessment 2). Eighteen students were in the SG and 12 in the NSG. Seventy-eight percent of the SG performed chest compressions between 90 and 110 per minute during Assessment 1, compared with 50% during Assessment 2. The NSG had an 8% success rate at both assessments. Compression rate variance did not change in in either group over time. Mental metronomes are valuable teaching tools that can help students to perform chest compressions at the recommended rate.

Summary

Methods

Gees’ “Stayin’ Alive”[2] while practicing chest compressions and were instructed to being promoted by the British Heart Foundation hands‐only CPR campaign and had an of 100 compressions per minute (CPM) Those in the SG listened to the chorus of the Bee synchronize their compressions with the beat of the song. The song was chosen as it was discernable rhythm of 103/min.[7] Participants in the NSG did not listen to a song during practice and instead were instructed to perform compressions at 100 CPM with no specific instructions on how to do so. As needed, with their compression rate being measured in real time with software The their compressions.[3] Following a short break both groups were asked to perform chest instructed to think about the song during this period. As this target differed from the current effect of changing the target rate to match the guideline recommended compression rate of
