Problem statement

Every minute is crucial when providing aid to someone who has an out-of-hospital cardiac arrest (OHCA). The highest survival rates are achieved when the patients receive defibrillation as fast as possible. The time it takes for an ambulance to arrive, however, is usually too long to ensure good survival odds for the patient. In order to reduce the average time between an arrest and defibrillation, automatic external defibrillators (AEDs) are placed in public areas. These AEDs are placed in cabinets that are often locked, so they are protected from acts like vandalism. The people that can access them are usually the owner(s), their employees, and citizen responders. Citizen responders are people who have followed CPR and AED courses and are registered in a national database. When an OHCA occurs, nearby citizen responders are alerted via text message to the location of the closest AED and the place of the incident. They have an app on their phone which provides them with the code that unlocks the cabinet. However, because the situation is both stressful and extremely time-sensitive, the time and effort it takes to read and input a code correctly is unwanted. The aim of this project is to remove this process and thereby reduce the average time between an arrest and defibrillation.

Objectives

The main objective is to design a new locking system for a publicly placed AED. First, anyone with the right clearance has to be able to access the AED as fast as possible, without having to do any additional actions like filling in a code. Second, the AED must be protected from incidents like vandalism and should not be accessible to anyone that is not authorized to. To meet these requirements, the design will include an app on the smartphone of someone who should have access and a way to determine the distance between this person and the AED. When someone has the app and is physically close to the AED, the cabinet should be unlocked automatically without any other user input needed.
