Google's Pixel Watch 3 is rolling out Loss of Pulse Detection in the US, following FDA clearance and a European launch last year. The feature, accessible through updated Wear OS and companion apps, uses multiple sensors and AI to detect a loss of pulse, potentially indicating a medical emergency. If no response is detected, the watch automatically contacts emergency services with location details. Google emphasizes that this feature isn't a replacement for medical monitoring and may not detect all instances of a loss of pulse.
