Current situation of emergency medical assistance indicates the need to organize faster and more efficient system of linking all the parts of the Republic of Croatia. The solution can be found in the implementation of aviation as the fastest and therefore the best method of transporting the injured, diseased and other persons who need urgent transport. The use of military helicopters for the purposes of emergency aviation does not satisfy the needs of the Republic of Croatia from the organizational and legal aspect. There were 597 fatalities on the Croatian roads in 2005 and with the establishment of emergency helicopter medical service, the number of fatalities may be reduced by one third.
