HemoHelper

An app that notifies emergency services when a user's blood oxygen levels are low.

Inspiration

In light of the pandemic, we wanted to create a product that would reduce fatalities related to Covid-pneumonia. One of our member's fathers suffered from suddenly low blood oxygen levels and we quickly learned the importance of blood oximeters in caring for the sick, elderly, and even athletes.

What it does

This is an Android app that connects via bluetooth to a wearable blood oximeter (such as an Apple watch, Fitbit, or ring). The app immediately calls 911 and notifies an emergency contact in the event that the user's blood oxygen level dips below a risk threshold. Additionally, the app tracks the user's location.

How I built it

We used an Arduino Uno with a bluetooth module to generate blood oximeter data and built the app through Android Studio and various Android APIs.

Challenges I ran into

We are 3/4 emerging and 3/4 non-CS engineers, so we had a lot to take in! The workshops and mentors at this event were extremely helpful.

What's next for HemoHelper

Ideally we would have liked to include a more seamless user interface. We also would like to be able to allow users to create personalized texts and play audio on outgoing calls. A resource page, including nearby healthcare providers and patient history would also fulfill the user's medical needs.
