Google is beginning to roll out its Loss of Pulse Detection feature to Pixel Watch 3 owners in the U.S.
Loss of Pulse Detection, the smartwatch’s marquee health feature, calls emergency services if the Pixel Watch 3 can’t pick up your heartbeat while wearing it.

However, because this is a high-stakes feature, it requires regulatory clearance — something Google didn’t get from the Food and Drug Administration until late February. Google says in a fact sheet that it tested the algorithm with over 100,000 hours of data to minimize false alerts, and has published a peer-reviewed study in Nature.
