U.S. Google Pixel Watch 3 users can now access a new feature designed to detect a loss of pulse, potentially aiding in life-threatening medical emergencies. Recently cleared by the FDA, this innovative tool utilizes an AI-based algorithm alongside a multipath heart rate sensor to identify conditions such as cardiac arrest, poisoning, or respiratory failure.
When the watch detects a loss of pulse, it activates additional sensors to search for signs of pulse or movement. If these signals are absent, the device prompts the wearer with alerts. Should there be no response, the watch emits a loud sound and begins a countdown before automatically calling emergency services via its LTE connectivity or a paired smartphone. This feature aims to address instances where emergency assistance may be delayed, particularly in unwitnessed events where bystanders are unavailable to intervene.
The development of this feature involved collaboration with cardiologists and emergency medical professionals to ensure its effectiveness and reliability. Google emphasizes that this tool is not intended for individuals with preexisting heart conditions or those needing continuous cardiac monitoring.
Originally announced in August, the pulse detection feature was first available in select countries, including the U.K. and several European nations, before its rollout to 14 countries, culminating in its availability to U.S. users. This expansion showcases Google's commitment to enhancing personal safety through technology.
