On Wednesday, Google received FDA clearance for the Pixel Watch 3’s “loss of pulse detection” feature, and announced it will be released in the US at the end of March.
This feature can detect events like primary cardiac arrest, respiratory or circulatory failure, overdose, or addiction that cause the user’s heart to stop beating. If the clock detects loss of pulses, the user will ask if it is OK. If they do not respond, the watch will automatically call emergency services to save lives.
The loss of pulse detection, first launched in the EU in September 2024, is currently available in 14 countries.
When Google announced the feature created at last year’s Google Event, the company said it decided that the clock would determine the loss of the pulse event by not only checking the user’s pulse but also considering other physiological and motion data. Next, we link these factors together via smart AI-driven algorithms.
Google says, “The loss of pulse detection does not detect all instances of pulse loss and does not target users with existing heart disease or those requiring cardiac monitoring. It does not diagnose or treat a medical condition or provide follow-up care. Emergency calls rely on call features such as the phone or clock being charged and having the right mobile phone connectivity.”
New features will take part in other safety and health features on the Pixel Watch, including car accident detection, fall detection, irregular cardiac rhythm notifications, and an ECG app.
