The aim of the study was to assess the influence of chest compressions feedback devices on the quality of chest compressions (CC) in healthcare providers. Materials and methods. Study was performed in 40 healthcare professionals in Moscow Federal hospital in 2017-2018. Chest compressions were assessed in 2 steps by means of CPR-challenge tool: 2 mins of CC without feedback then 2 mins of CC with feedback on rate, depth and CC release velocity (CCRV) (ZOLL R-series defibrillator). The ERC Guidelines for Resuscitation 2015 were used as reference criteria for CC quality. The analysis was performed using the ZOLL RescueNet Code ReviewR software. Statistical analysis was done by Statistica 7.0 (Student T-test). Data were presented as mean±SD. Difference was considered significant at P<0.05. Results. Without feedback devices the quality of CC was extremely low (rate 124,9±22,3 cpm; depth 4,6±1,1 cm; CC in target 5,4±18,3%; CCRV 324,5±93,5 mm/s), but it significantly improved with feedback devices (rate 111,9±7,3 cpm; depth 5,2±0,4 cm; CC in target 68,3±26,4%; CCRV 352,1±40,2 mm/s). CCRV was moderate and did not improve with feedback devices. Conclusions. Chest compression feedback devices positively influence the quality of CC in simulated environment in healthcare providers. Improvement of CC depth, rate and CC in target without any improvement of CCRV was detected.
