Out-of-hospital cardiac arrest (OHCA) is a leading cause of sudden death in India, hindered by low survival rates, lack of public awareness, and a shortage of automated external defibrillators (AEDs). Socio-cultural barriers also impact timely aid for female victims. This project designed a holistic ecosystem of solutions to improve cardiac arrest survival by addressing challenges across detection, emergency response, and bystander CPR knowledge. Through secondary research and interviews with survivors and professionals, insights were mapped across the rescue journey to identify critical pain points. An iterative approach led to a suite of solutions targeting specific problems at each stage of the rescue flow. The resulting ecosystem is scalable and culturally sensitive, aiming to strengthen India’s emergency response landscape. By empowering everyday people to act quickly and confidently, these solutions reduce response times and increase the likelihood of survival. Ultimately, the project demonstrates the potential of design to save lives through public emergency preparedness.
