Improvement of the quality of cardiopulmonary resuscitation performed with Real CPR Help® device among medical students and medical workers.

Introduction: This study aimed to compare the quality of CPR performed with real-time feedback device with CPR delivered without it by medical students and practising medical workers. Material and methods: Studied group consisted of 96 participants. Real CPR Help® technology providing real-time feedback was used. The following parameters were measured: mean depth, mean frequency, adequate depth rate, adequate frequency rate, and general compressions quality. Participants performed one-minute cycles of CPR with and without the feedback. Results: Mean compression depth lowered with the feedback (6.1 ± 1.3 cm vs. 5.3 ± 0.4 cm; p < 0.001) and the number of participants with adequate depth increased (25% vs. 78,1%; p < 0.001). Mean compression frequency lowered after the use of the device (119.8 ± 16.8 cpm vs. 111.9 ± 6.9 cpm; p < 0.001) and the number of participants performing CPR with recommended compression frequency increased (50% vs. 86.5%; p < 0.001). Overall quality increased significantly with the feedback (0.0; IQR: 0.0–13.7 vs. 55.1; IQR: 31.5–78.8; p < 0.001). Similar CPR quality was observed in the student group vs. medical workers without the feedback (0.81; IQR: 0.0–16.2 vs. 0.0; IQR: 0.0–12.7; p = 0.27) and after the device implementation (61.26; IQR: 38.16–80.0 vs. 49.54; IQR: 30.06–65.84; p = 0.21). Conclusions: The use of the Real CPR Help® device in the simulated test improved the overall quality of CPR. There were no differences concerning CPR quality between students and medical workers after the device implementation.
