Berkeley student’s startup aims to detect stroke signs and save lives

In the United States, someone suffers a stroke every 40 seconds, and every three minutes, a life is lost to this medical emergency. Recognizing the critical need for prompt detection and intervention, UC Berkeley undergraduate Ashmita Kumar has founded Code Blue, a startup harnessing artificial intelligence (AI) to identify early signs of stroke using everyday devices like smartphones and computers.​

The Genesis of Code Blue

Ashmita Kumar, a third-year student majoring in electrical engineering and computer sciences, was inspired to develop Code Blue after observing the widespread adoption of telehealth and the ubiquity of smart devices. She envisioned leveraging existing technology to provide timely alerts for stroke symptoms, thereby facilitating quicker medical responses and potentially reducing long-term disabilities.

How Code Blue Works

Designed for individuals at elevated risk of stroke, Code Blue operates seamlessly on devices such as smartphones, computers, and smart TVs. Once activated, the program periodically analyzes the user’s speech and facial expressions, monitoring for indicators like slurred speech or asymmetrical facial movements. If potential stroke symptoms are detected, Code Blue alerts the user and can notify emergency services, ensuring that patients receive prompt and appropriate medical attention.

Pilot Testing and Future Aspirations

Currently, Kumar is collaborating with medical professionals at UC San Francisco to pilot Code Blue with a select group of patients. Plans are underway to expand the testing cohort and pursue approvals from the U.S. Food and Drug Administration (FDA). Such endorsements would facilitate broader adoption of the technology, akin to other consumer health innovations like the Apple Watch’s heart monitoring features.

Support from UC Berkeley’s Entrepreneurial Ecosystem

Kumar’s journey has been bolstered by UC Berkeley’s robust support for student entrepreneurs. She has participated in programs at the Sutardja Center for Entrepreneurship and Technology and secured the grand prize in the Blum Center’s Big Ideas Contest. Additionally, her involvement with the National Science Foundation I-Corps boot camp and the UC Launchathon at Berkeley Haas has provided valuable resources and mentorship, underscoring the university’s commitment to fostering innovation with societal impact.
