The influence of real-time feedback on the quality of resuscitation: a prospective study comparing bystanders, paramedic course participants, and emergency physician trainee

The aim of this study was to analyze the potential benefits of real-time feedback in resuscitation training for participants in the prehospital emergency chain and to compare differences in the quality of chest compressions (CC) with and without feedback. The primary endpoint was to analyze the proportion of CC achieving the recommended depth (5-6cm) and frequency (100-120 / min) during two minutes of CC. This prospective cohort study compares bystanders (N = 75), paramedic trainees (N = 75), and emergency physician trainees (N = 75) with and without the feedback system of the Zoll X-Series®. Without feedback, paramedics (P) achieved the target compression frequency in 82.7 %, bystanders (B) in 49.8 % and emergency physician trainees (EP) in 75% (P vs. B, p < 0.001; EP vs. P, p = 0.759; EP vs. B, p = 0,217). There were no significant differences in target compression depth without feedback. With feedback, P achieved the compression frequency in 90.7%, B in 72.8% and EP in 91.4% (P vs..., *Study design
*The prospective cohort study was approved by the ethics committee of “Medizinische Hochschule Brandenburg” (E-01-20200403).
*Participants/study population
*The recruitment and data collection were conducted at the state-recognized emergency medical school in Berlin. A total of 225 participants from first aid classes (B), paramedic classes (P), and emergency classes for physicians (EP) voluntarily participated in the study outside of class hours. Before the start of the study, the B participants acquired theoretical knowledge on performing chest compressions (CC). At the time of data collection, the P cohort had completed four weeks of theoretical and practical instructions and was about to begin hospital and ambulance internships. The EP cohort consisted of licensed physicians participating in an emergency physician class.

## Description of the data and file structure

This dataset contains quantitative performance data on chest compressions (CC) obtained from a prospective cohort study conducted at the state-recognized emergency medical service school “NAW Berlin.” The study investigated whether real-time feedback improves resuscitation quality across three participant groups: bystanders, paramedic course participants, and emergency physician trainees.

Each of the 225 participants performed two standardized 2-minute chest compression trials on a resuscitation simulator (AmbuMan®) with a real-time feedback system (Zoll X-Series®):

1. One trial without feedback (WoF)
2. One trial with feedback (WF)

Both trials were performed under identical, standardized conditions. The feedback system displayed and recorded compression dept...,
