The Pixel Watch 3 Is Finally Getting Its 'Loss of Pulse” Update

Pixel Watch 3's Life-Saving Pulse Detection Feature Now Available in the US

Google's Pixel Watch 3 has received an FDA-approved update, enabling its crucial Loss of Pulse Detection feature. This AI-powered functionality monitors heart rate, alerting users and potentially contacting emergency services if a pulse is not detected.

Initially launched without this key feature pending FDA approval, the Pixel Watch 3 now offers enhanced heart rate monitoring. The update addresses a previous limitation, providing more consistent readings, particularly beneficial for fitness tracking and emergency situations.

The watch employs sophisticated algorithms: a passive sensor checks the pulse every second, while active sensors verify readings, minimizing false alarms. A multi-stage alert system notifies the user; if no response is received, emergency services are contacted.

Google's AI analyzes heart rate and movement data to identify pulse loss, going beyond basic pulse monitoring. While not foolproof (false positives and negatives are possible), users can easily dismiss false alarms.

Important Note: This feature is not a replacement for professional medical devices. It's not intended for individuals with pre-existing heart conditions or those needing continuous cardiac monitoring. Emergency calling relies on sufficient signal strength and battery life, with Wi-Fi-only models requiring a phone connection.

The Loss of Pulse Detection is activated through an update to the pre-installed "Personal Safety" app, accessible under "Safety & Emergency." This is separate from a recent bug-fixing update.
