Researchers at the University of Washington have developed an algorithm for a smart speaker or smart phone to identify cessation of breathing or gasping of air that most people experiencing a cardiac arrest will display, and raise the alarm. In tests, these so-called agonal breathing events were detected 97% of the time from up to 20 feet away.
Dr Jacob Sunshine, an assistant professor of anaesthesiology and pain medicine at the UW School of Medicine, said: “This kind of breathing happens when a patient experiences really low oxygen levels. It’s sort of a guttural gasping noise, and its uniqueness makes it a good audio biomarker to use to identify if someone is experiencing a cardiac arrest.”
“Cardiac arrest fatalities could be reduced by Smart speakers“
Shyam Gollakota, an associate professor in the UW’s Paul G. Allen School of Computer Science & Engineering, said: “A lot of people have smart speakers in their homes, and these devices have amazing capabilities that we can take advantage of. We envision a contactless system that works by continuously and passively monitoring the bedroom for an agonal breathing event, and alerts anyone nearby to come provide CPR. And then if there’s no response, the device can automatically call 911.”
