Mobile intensive care units (MICU) will take care of all real emergency patients with presumed or proven disturbances of vital functions. These vehicles are equipped according to standardized criteria, and usually stationed at emergency hospitals. MICU's are accompanied by one rescue assistant, one emergency medical technician (EMT) and one physician.

Eighty-five to 90% of the total number of emergency calls were primary emergency calls, where the emergency patient had to be treated at the scene; 10% to possibly 20% were emergency patients who had already received treatment by medical or paramedical personnel.
