How to Activate and Optimize Loss of Pulse Detection on Your Google Pixel Watch 3

The Google Pixel Watch 3s Loss of Pulse Detection is a groundbreaking safety feature designed to automatically alert emergency services if a sudden pulse cessation is detected. To use it, ensure the watch is snugly fastened, enable the feature in the Fitbit apps safety settings, and confirm LTE connectivity for emergency calls. The system employs a multi-stage algorithm using green PPG sensors, infrared and red lights, and accelerometers to detect pulselessness, followed by escalating haptic, visual, and auditory alerts to verify responsiveness. If unaddressed, the watch shares the users location and triggers an automated emergency call. Rolling out globally after FDA approval, this feature enhances safety during cardiac events, respiratory arrests, or poisoning incidents where immediate intervention is critical. Proper setup and situational awareness help minimize false alarms while maximizing its lifesaving potential for unwitnessed medical emergencies. --- Note: The actual content from the provided URL is not available in the search results.
