Inspiration

When someone calls 911 for a cardiac emergency, the time before the ambulance arrives is often the most critical — and sometimes, the most wasted. Many bystanders don’t know how to perform CPR or where to find an AED nearby. Some might struggle with language barriers or have difficulty following audio instructions over the phone. This inspired us to create a web-based tool that bridges this gap — allowing 911 responders to send callers a link that instantly guides them through CPR and shows the nearest AED locations.

What it does

Our platform provides clear, visual CPR instructions through a short video and an interactive AED locator map. The map not only uses Google Maps to guide users to the closest building with an AED but also includes an indoor navigation feature that visually directs users step-by-step to the AED’s exact location inside the building.

How we built it

We developed a mobile-friendly web application using web design and AI-assisted tools. We integrated Google Maps APIs to display real-time locations and AED markers and designed a responsive user interface that prioritizes speed, clarity, and accessibility during emergencies.

Challenges we ran into

Creating detailed indoor navigation maps was one of the biggest challenges. While outdoor navigation is easily supported by APIs, accurate indoor mapping requires building-specific data, layouts, and path planning, which we plan to improve in future iterations.

Accomplishments that we're proud of

We’re proud that our project directly addresses a real-world problem — reducing the response time in emergencies and potentially saving more lives. By turning the critical waiting minutes into active rescue time, we can help bystanders become immediate responders.

What we learned

We learned that in medical emergencies, every second counts — time truly is gold. Designing for clarity and speed under pressure requires thinking from the perspective of someone panicking yet determined to help.

What's next for SOS

Our next step is to expand the system with accurate, building-specific indoor maps and real-time AED databases. We also hope to collaborate with emergency response centers to integrate our platform into existing 911 workflows.
