FDA Clears Pixel Watch 3's Life-Saving Loss of Pulse Detection for U.S. Users

The feature, already available in 14 European countries, will roll out to U.S. devices by the end of March.

Google's Pixel Watch 3 has received FDA clearance for its Loss of Pulse Detection feature, enabling automatic emergency calls if a user's pulse stops and they are unresponsive.
The feature uses AI and multipath heart rate sensors to detect pulse loss due to events like cardiac arrest, respiratory or circulatory failure, overdose, or poisoning.
If no pulse is detected, the watch initiates a series of checks, sounds an alarm, and, if no response is received, calls emergency services and shares the user's location.
Developed with input from cardiologists and tested using stunt actors and clinical data, the feature has been available in 14 European countries since late 2024.
The rollout in the U.S. is scheduled for the end of March and will join other Pixel Watch safety features like Fall Detection and Car Crash Detection.
