Vienna has a modern ambulance service/rescue mission system that I had experienced first hand. First was when I gave birth to my youngest, it was the red cross ambulance that came, I was attended by a younger crew who were finishing their Civil Service requirements. Then the next time I dialled 144 was 10 days ago.
There is a wide distribution of the ambulance stations in each of Vienna's 23 districts. There are 12 stations of the Viennese Rescue and 7 more of the Red Cross, Arbeiter Samariter Bund and Johanniter Unfall Hilfe. The stations are in such a way distributed over the city that the vehicles usually reach the place of work within twelve minutes after the alert.
Apart from the very prompt response, hats off to the very friendly attendants who would give a joke or two to put the patients at ease.
