Automated External Defibrillators (AED’s) are lifesaving devices that can greatly improve the survival rates of cardiac arrest when used quickly. There are publicly accessible AED’s on the UNM campus, and each device has an effective range based on how quickly a responder can retrieve the AED and return it to the site of the cardiac emergency. The ranges of the AED’s on UNM central campus are analyzed using GIS, interior building measurements, and various retrieval speeds. This helps evaluate the current placement of AED’s on campus and helps reveal where future coverage is needed. This focus on the combined navigation of both interior and exterior spaces creates unique considerations from a geographic theory perspective. Coverage at UNM varies according to the retrieval speed, but using American Heart Association guidelines, less than a quarter (~11-24%) of the exterior space on central campus is covered by an AED.
