Abstract Evaluation of contributing factors to successful CPR following out- of-hospital cardiac arrest Oleksandr Opanasenko, Eva Havlikova, Volodymyr Kizyma Falck Zachranna, Kosice, Slovakia Corresponding author: kizyma@falck-zachranna.sk Keywords: out-of-hospital cardiac arrest, successful resuscitation, high-quality chest compressions Aim: ERC Guidelines define effective bystander BLS, high-quality chest compressions and early defibrillation as the main contributing factors to improve survival after cardiac arrest. Falck Zachranna, the leading EMS provider in Slovakia, uses a Physio-Control software to abstract from defibrillator recordings and analyze parameters of the real CPR such as chest compressions and ventilation parameters. The aim of our study was to evaluate the abovementioned factors influence on survival odds in patients after out-of-hospital cardiac arrest (OHCA). Methods: Authors analyzed 193 cases of shockable OHCA where patients developed sustained return of spontaneous circulation (ROSC) and were transported to hospitals. The data were gathered from September 2015 till December 2017. Authors focused on such parameters as bystander BLS, chest compressions ratio and rate, ETCO2 concentrations and time to first shock. The chest compressions ratio and rate and ETCO2 concentrations before ROSC were chosen as the indicators of uninterrupted, high-quality chest compressions. Results: The median figures for the chosen parameters were the following: compression ratio 85%, compression rate 111/min, pre-ROSC ETCO2 30 mmHg, time from OHCA confirmation to first shock 20.50 sec. The average results for the compression parameters were the following: compression ratio 82.5±11%, compression rate 112±10/min. Contraversively, 14.5% of the patients (n=28) had no bystander BLS. Conclusion: Authors believe that the acquired figures of compressions ratio and rate and pre-ROSC ETCO2 could be considered as possible performance targets for high-quality chest compressions. Yet, a study needs to be fulfilled about relationships of the factors and long-term patient survival following OHCA.
