Summary Summary: Main problems of the emergency medical team in a changing environment are inadequate docu-mentation and data-interpretation as well as the deficit in cooperation with all other participants in the res-cue-process. The article describes experience with improved documentation by computer-systems and gives an overview of current solutions in Germany.The increased use of computers in emergency medical services is a requirement for further integration of the medical team on the scene. Other current projects show how this can be realised in the future. By taking data from the ecg/defibrillator, by exchanging data with the headquarters, by sending information to the hospital and by retrieving emergency data sets via internet the emergency physician will be enabled to become the manager of the patient and will be able to pick the most adequate therapy for the patient and for the health system.
