If your heart stops, this smartwatch-AI can call for help

00:47 A ‘smart’ way to quickly detect cardiac arrest

Google researchers have developed an AI for a smartwatch that will call for help if its wearer is having a cardiac arrest. Trained, in part, on data gained when patients had their hearts deliberately stopped during a medical procedure, the team’s machine learning algorithm can automatically detect the telltale signs of cardiac arrest. The team think this system could save lives, although more testing is required. "Our hope is that as these capabilities expand it provides a new way to keep people safer,” says Jake Sunshine, one of the researchers behind the study.
