The US rollout for the Loss-of-Pulse detection feature on the Google Pixel 3 starts today. The feature identifies when your pulse is lost and can automatically call emergency services if you’re unresponsive. You can expect a prompt will pop up on your watch to enable it. Don’t worry if it hasn’t happened just yet — the roll-out is estimated to last a few weeks.
Google announced the Loss of Pulse Detection feature in 2024 for select EU countries and received FDA clearance in the US in February.
The watch uses an AI-based algorithm and signals from the existing multipath heart rate sensor (the flashing green light on the back of the watch) to monitor your pulse. If it suspects your pulse was lost, additional sensor signals will be activated to search for the pulse or identify movement.
When nothing is detected, the watch prompts you with an initial check-in. If you don’t respond to the message on the watch and no motion is detected, a loud alarm will play, and a countdown will appear on the screen. Then, an emergency services call is placed on your LTE smartwatch or phone. An automated message about the loss of pulse and your location will be shared with emergency operators.
While the Loss of Pulse Detection feature wasn’t made for any one specific health condition, this is another feature added to the Pixel 3’s impressive catalog of safety and health features, such as fall detection and irregular heart rhythm notifications. As a Google Pixel user, I’m happy to see another feature in the medical safety space, especially for one in which immediate intervention is necessary.
