Aim The Aim of the research is to determine the connection between EtCO2 and pulse-oxymetry and surviving and favourable outcome of OHCA victims,as an upgrade from OHCA International Studies ' EuReCa_ONE ",in Indjija's emergency service. Methodology: The study was conducted as a prospective-observational study out-of-hospital cardiac arrest between 01.10.2015-31.12.2016., according to the methodology EuReCa_ONE study in 2015.,which followed next 15 months. Data on the SCD are administered in a questionnaire "Utstein" Style. In addition to the questionnaire EtCO2 and SaO2 value were monitored:the initial-EtCO2 and SaO2 , EtCO2 and SaO2 in the second minute, the final EtCO2 and SaO2 and average value of EtCO2 . Results: In the victims who did not achieve ROSC initial EtCO2 was 7.1mmHg, 12,9mmHg the average and final 11,7mmHg. Average EtCO2 after 2-minutes was 11mmHg. When the victims achieved ROSC initial EtCO2 was 14.65mmHg,average 23,1mmHg and 26.71mmHg final. Average EtCO2 after 2 minutes was 25.77mmHg. In the victims who did not achieve ROSC initial SaO2 was 14.1%,78,5% the average and final 45,3%. Average SaO2 after 2 minutes was 69%.When achieved ROSC initial SaO2 was 21,2 %, average 79,4% and 82,1% final.Average SaO2 after 2 minutes was 71,1. Conclusion: The trend of increase in EtCO2 after 2-minutes is the most important predictor of ROSC. The upward trend in EtCO2 after 2 minutes could be a good indicator of the outcome and further research is needed. Values of EtCO2 and SaO2 are not in correlation during resuscitation, also the values of SaO2 does not predict outcome but SaO2 is sign of good resuscitation.
