The work presents training system which provides a structured, simple and practical approach to triage training, for first response paramedic and emergency medical services personnel, as implementation of the triaging procedures in mass casualty accidents. The proposed training system allows to train the procedures at all three levels of hierarchical chain of strategic, tactical and executive command management. It provides reliable connectivity at the scene based on Bluetooth Low Energy standard or Internet connection with the use of mobile 4G LTE communication networks infrastructure. In training system we use simulators of vital human signs based on mobile devices, which generate so-called the victim's life cycle chart, consisting of the heartbeats and respiratory rates, systolic and diastolic blood pressure, and capillary refill time, used a the basis for triage categorization. Presented training system increases trainees competence level in executive as well as control and governance skills.
