When Google launched the Pixel Watch 3 this past August, one of the more unique tools introduced on the lineup was the device's new Loss of Pulse detection. A potentially life-saving health feature, Loss of Pulse detection can identify if a user's heart stops beating due to an emergency like cardiac arrest, poisoning, or respiratory arrest. The tool then notifies emergency services automatically to ascertain help. However, Loss of Pulse detection originally landed with only regional availability and a vague promise of further expansion in the months to follow. Today, Google rolled out the feature to users in Belgium, Italy, and Spain, but left US Pixel Watch 3 users still waiting.
