This master's thesis analyzes interventions and responses of the Dispatch Service of the University Medical Center (UKC) Ljubljana Emergency Medical Station from 2005 to 2014. It also presents the legislation and other regulations pertaining to the medical emergency services in Slovenia and abroad. Based on various analyses the subdivision of interventions was displayed in terms of days, weeks, and years. Certain assumptions regarding standard response times, call received times, the emergency medical attention teams response times and others were verified. Global autocorrelation statistics was used in determining and confirming the spatial interconnection of the data. It was verified autocorrelation of travel time. The kriging method was used to make emergency medical teams travel time charts. Based on statistical spatial analyses the probability of emergency occurrences in areas covered by the UKC Ljubljana Emergency Medical Station was displayed along with areas that merited a greater coverage with emergency medical assistance station branches. It was verified, based on the automatic external defibrillator locations and locations of events of cardiac arrest, coverage of the analyzed area with installed defibrillator, and additionally which areas suffer from a poor or an inadequate access to a defibrillator.
