INTRODUCTION: Cardiac arrest represents one final cascade of adverse events during many emergencies, often in the prehospital settings. Institute for Emergency Medical Care Niš enroled international prospective EuReCa (EUropean REgistry of Cardiac Arrest) ONE study with the aim to follow up and investigate the problem of out-
AIM: The aim of this study was to evaluate the activation patterns of emergency medical service from dispatch call to defining factors in decision to resuscitate in cases of OHCA.
METHOD: Prospective data of the occurrence of OHCA, EMS activation data and factors determining decision to start cardiopulmorary resuscitation (CPR) during the period 01. October 2014. -
RESULTS: The average trigger time for all calls was 3 minutes 5 seconds: 13 seconds for 1st, 1 minute 56 seconds for 2nd, 12 minutes 14 seconds for 3rd and 10 minutes 50 seconds for 4th order of priority of emergency calls (p<0.05). When receiving calls, a level of consciousness was possible to specify in 88.9% of cases, while the presence/absence of respirations was determined in 46.0% of cases (p<0.001). CPR measures were initiated in 53.97% of cases with confirmed OHCA. Using multivariate analysis of parameters which may affect the use of CPR measures in OHCA, order of priority of emergency calls (p<0.001), information on time of respiration cessation (p<0.001), the initial rhythm on the defibrillator monitor (p<0.05), information about terminal illness (p<0.05) and the time from departure to arrival at the scene (p < 0.001) were identified as important factors.
CONCLUSION: The trigger time for 1st order of emergency calls is impressive. Triage of emergency calls was done with insufficient data about the quality of breathing. Cases that are triaged to the highest priority of emergency calls, with information about the short time from the breathing cessation, with the initial schockable rhythm, with no bystander information about terminal illness and with shorter time from departure to arrival of the EMS team at the scene, had a significantly greater chance of CPR measures to be initiated
Key words:out of hospital cardiac arrest, cardiopulmonary resuscitation, CPR, EURECA ONE, emergency, ZHMP Niš.
