Google Pixel 3 Launches Loss-of-Pulse Detection Feature in the US
The much-anticipated Loss-of-Pulse detection feature for the Google Pixel 3 smartwatch is being rolled out in the United States starting today. This innovative safety enhancement is designed to identify instances where a user’s pulse is no longer detected and can automatically initiate a call to emergency services if the wearer becomes unresponsive. Users can expect a notification prompt on their device to enable the functionality. The complete rollout is projected to span several weeks, so patience is advised if the feature is not immediately available.
Background and Regulatory Approval
Google initially unveiled the Loss of Pulse Detection feature in 2024 for select European Union countries. Following this initial launch, the feature received clearance from the Food and Drug Administration (FDA) in the US in February, paving the way for its introduction to American users.
How Loss-of-Pulse Detection Works
This sophisticated feature leverages an advanced AI-driven algorithm and data from the existing multipath heart rate sensor – the green light on the watch’s underside – to continuously monitor the wearer’s pulse. Should the system suspect a loss of pulse, it promptly activates additional sensor signals to verify the condition and check for any body movement.
Emergency Response Protocol
If no pulse is detected and no movement is registered, the Pixel watch will initially prompt the user with a check-in notification. If there is no response to this message and no motion is sensed, the device will trigger a loud audible alarm, and a countdown timer will appear on the screen. Subsequently, an emergency services call will be automatically placed via the user’s LTE-enabled smartwatch or paired phone. A pre-recorded message detailing the loss of pulse incident and the user’s location will then be conveyed to emergency dispatchers.
Expanding Pixel’s Health and Safety Capabilities
While the Loss of Pulse Detection capability is not specifically targeted at any particular medical condition, it represents another significant addition to the Pixel 3’s comprehensive suite of health and safety features. These existing features include fall detection and irregular heart rhythm notifications, underscoring Google’s commitment to user well-being. For Google Pixel users, this new feature provides added peace of mind, particularly in situations where rapid medical intervention is crucial.
