Abstract: A system having preclinical emergency care modules which produce a complex condition dependent control system that is as integral as possible in combination with a human emergency worker. At the system level, an intelligent decision-making system is provided which leads to measures that are optimized for the situation with and without the emergency worker. The modules exhibit a different behavior depending on the situation and interaction. In the process, the emergency worker can be utilized as an additional sensor/actuator module. Based on all obtained sensor data, which is weighted differently, decision-making support is proposed to the emergency worker, or the system makes decisions automatically. The protected communication of the modules is of particular importance for this purpose.
