01Overview

Every Minute Before Arrival Matters

Despite calls to 120, many cardiac arrest victims perish before arrival. The critical Golden 4 Minutes before hospitalization significantly enhance survival chances, yet cardiac arrest's prevalence as a societal issue demands a rescue system that works across varied environments, from semi-closed spaces to open settings. This project streamlines pre-hospital emergency response, maximizing the potential to save lives.

02Design Objectives

What the System Had to Deliver

01

Design a rescue system that is accessible and usable in various environments, including semi-closed and open settings, to ensure widespread applicability.

02

Develop a system that enables prompt response to cardiac arrest incidents, minimizing the Golden 4 Minutes delay and maximizing the chances of survival.

03

Provide training and educational resources for users, including rescuers, bystanders, and healthcare professionals, to ensure proper use of the rescue system and optimize outcomes.

03High-Fidelity Design

A Control-Room View for Dispatch Operators

Built for backend operators, the interface pairs an intuitive map display with clear information indicators so they can precisely locate people in need and monitor the situation in real time. A concise, clear control panel lets operators execute rescue steps quickly, improving response speed.

04Product Design & Improvement

Built on the Existing AED, Made Easier to Use

This rescue device is designed based on the existing AED, providing user instructions and an added layer of usability assurance, allowing both trained volunteers and ordinary individuals to easily operate it in emergency situations.

05Blueprint

From Collapse to Hospital, Step by Step

When someone collapses, passersby scan a nearby emergency code to alert the control center, which confirms the incident and dispatches the response. Warning screens and AED signage draw in personnel and bystanders alike, improving response within the Golden 4 Minutes.
