Google has recently received FDA clearance for its loss of pulse detection feature, which is available on the Pixel Watch 3. This innovative technology is designed to monitor a user’s pulse continuously. When the system detects a potential loss of pulse, it activates infrared and red lights to search for additional pulse signals while a motion sensor checks for any movement. An AI algorithm then analyzes both the pulse and movement data to confirm whether there is a true loss of pulse.
If the watch determines that there is no pulse and the user does not respond during a subsequent countdown, it automatically calls emergency services and sends an automated message with the user’s status and location. Google first unveiled this life-saving technology at its Made by Google event last year alongside the Pixel Watch 3 launch.
Currently available in 14 countries, the FDA clearance means that the feature will soon be accessible to U.S. users of the Pixel Watch 3, with availability expected at the end of March. Jake Sunshine, a research scientist at Google, highlighted the significance of this milestone, stating that their extensive research and testing confirmed the potential of wearable devices to detect emergencies and improve health outcomes. He emphasized that this safety feature could make a meaningful difference, particularly in situations where individuals are alone and immediate assistance is critical.
In a discussion with MobiHealthNews at Google’s Bay View headquarters during the Made by Google event, Sunshine explained that the loss of pulse condition can affect anyone, regardless of age, and may arise from various causes, both cardiac and non-cardiac. Recognizing the time-sensitive nature of such emergencies, Google designed this feature to quickly connect users with help when needed the most. According to Sunshine, this loss of pulse detection technology is the first of its kind and represents a significant step forward in wearable health monitoring.
