Loss of Pulse Detection was announced last August as the Pixel Watch 3’s latest safety feature, and it has finally been approved by US regulators, with a rollout set for next month.
At launch last year, the feature was available in several European countries, but was awaiting Food and Drug Administration (FDA) clearance in the US. Today, Google announced that the approval has been granted.
A loss-of-pulse (“your heart stops beating”) event can be due to a cardiac arrest, respiratory or circulatory failure, overdose, or poisoning. When detected, the Pixel Watch 3 will prompt users to confirm they are okay, similar to Car Crash and Fall Detection.
If there’s no response or motion, the Pixel Watch 3 will call emergency services and provide your location, as well as the context.
Loss of Pulse Detection makes use of the Pixel Watch 3’s multipath heart rate monitor, other sensors, and a “multi-check, AI-based algorithm,” which has been tested with over hundreds of thousands of hours of data.
Officially, “Loss of Pulse Detection may not detect every instance of a loss of pulse and is not intended for users with pre existing heart conditions or those who require cardiac monitoring. It does not diagnose or treat any medical condition or provide follow-up care.”
Once rolled out, you have to enable it from the Pixel Watch app on your phone > Safety & emergency.
Loss of Pulse Detection is currently available in 14 European countries (full list below) and will “begin rolling it out in the U.S. at the end of March.” It joins other features on the Pixel Watch 3 like Irregular Heart Rhythm Notifications and the ECG app.
