Final answer:
Dispatch Triage is the system used to evaluate and prioritize emergency calls for EMS response, ensuring critical cases receive the fastest response by using call classification and priority coding.
Step-by-step explanation:
The system that helps categorize emergency calls for EMS response is known as Dispatch Triage. Dispatch triage involves evaluating and prioritizing incoming emergency calls based on the severity and nature of the reported incident. This process ensures that the most critical cases receive the quickest response. A dispatcher will typically ask a series of questions aimed at classifying the urgency and type of assistance required.
By using a standardized system such as the Emergency Medical Dispatch (EMD) protocols, dispatchers can provide call classification which directly impacts the type and speed of the response dispatched to the scene. A priority coding system within the triage method often categorizes incidents into different levels of response, ranging from life-threatening emergencies to non-critical services.
