AMPDS

AMPDS is the system used by ambulance services across the world, and organises calls in order of priority. For example, if there was one ambulance and two people need it, it's not organised on a first-come-first-served basis. If a 65 year old man with chest pain needs it, and so does a 7 year old girl with a suspected broken leg, the AMPDS system would prioritise it so that the 65 year old gets it.
