CANNE

What it does

CANNE provides a corrugated cardboard learning kit and basic life support application to motivate laypeople to learn CPR at a low cost. It saves time and medical resources and has a minimum requirement for the learning environment.

Your inspiration

More than 540,000 Chinese people die from sudden cardiac death each year. The survival rate of out-of-hospital cardiac arrest is less than 1% in China. Some main problems cause this low rate: The lay public has less motivation to join a CPR course because of fewer interests and a fast-paced lifestyle. The less qualified full-time instructors are other significant barriers to teach quality life-saving skills. Besides, the CPR training equipment is too expensive for this vast population. My project focused on providing a flexible self-directed CPR learning solution to encourage more laypeople to learn and improve their life-saving skills.

How it works

A corrugated cardboard basic life support (BLS) learning kit that allows laypeople to practice CPR, such as cardiac arrest identification, chest compression and ventilation by themselves. The cardboard manikin includes a compact chest and head. The accessories include paper lungs, recycled plastic mouthpieces and a card with a learning App's QR-code. The BLS self-directed application on the smartphone can enhance the learning experience by simulating cardiac arrest scenarios with AR technology, also it guides the user to perform chest compression in the right position and accurate gestures. Besides, the artificial intelligence dispatcher provides conversations like emergency medical services (EMS) for laypersons. The built-in front camera and microphone on the smartphone can provide real-time feedback of compression and ventilation. Once the practice's time reaches a standard level, the user can join a final examination and get an online BLS certificate.

Design process

The project started with a CPR learning course to learn how to perform CPR. To get holistic insights about cardiac arrest and CPR training situations in China, I conducted multi interviews with different stakeholders such as instructors in the Redcross and training centres, ambulance doctors and CPR learners. The ideation ran in parallel with interviews, rapid prototyping, user journey map and scenario exploration. It helped evaluate the different directions and clear the design opportunities during the expert interviews. During the concept development phase, multi cardboard manikins iteratively improved the solution over time, increasing the user experience such as compact cardboard manikin assembly and feasible visual guidance printed on the cardboard. To make the functions such as the AR scenario more tangible, a functional prototype of the UI/UX was created using Figma, Adobe Aero and After Effects. A usability test was conducted with different laypersons by observing and discussing the assembly of cardboard manikins and chest compression with a UI/UX prototype. The feedback of manikin assembly and chest compression is super reliable and uplifting because the feeling of performing CPR with CANNE is close to an advanced manikin such as Little Anne.

How it is different

In developing countries, it is difficult to increase the survival rate of out-of-hospital cardiac arrest because of the low implementation rate of CPR training. The cost and amount of CPR training products far limited the number of participators who can join a CPR course. Currently there is no solution which is supporting self-directed quality CPR learning for the lay public in developing countries. This way CANNE provides an ecosystem to motivate more laypeople to learn CPR by themselves and it can be accessible to all the regions where people have a smartphone. The laypeople can pick CANNE from local Redcross or their company, as well as ordering them online at a low cost. When comparing to today's onsite CPR training, CANNE even enhances the cardiac arrest scenario simulation with AR and AI technologies. CANNE could raise the survival rate of out-of-hospital cardiac arrests, particularly in China, by addressing the local, societal and cultural needs.

Future plans

I am currently looking into how I can move forward with this project and would love to reach the market and improve the life-saving skills of the lay public in China. As a designer, I have highly valued the final design in a sustainable vision. The next steps are iterating the physical and digital product, such as simplifying the assembly process and decreasing the colour of prints on cardboard for a sustainable and lower cost purpose. Besides, working with the collaborated company to test it in a current process.
