FDA clears Google smartwatch tech that calls 911 when a user’s heart stops

Google has received U.S. Food and Drug Administration (FDA) for Loss of Pulse Detection, a new smartwatch feature that detects when a person’s heart stops beating and then automatically alerts emergency services.

Loss of Pulse Detection asks the user if they are OK when it first detects the loss of pulse. If no response is provided, it triggers an audio alarm and countdown to when emergency services will be notified. If the countdown reaches zero, the alert is officially sent out.
