The discussion was conducted focusing on the two rendezvous methods that cannot be missed on air ambulance dispatches.
Based on the dispatch recording of air ambulance in the Hokusoh hospital, the flight time of air ambulance from the request to the arrival on the Rendezvous point was verified by each municipality. And the sphere, which is close to the current state of air ambulance dispatches by region, is analyzed and visualized. Hence the basic data was developed, that is available for building the existing area by collaboration of emergency vehicles and air ambulance for the emergency medical system.
