In a blog post today, Google announced that it received FDA approval for the loss of impulse detection.

Follow your heartbeat

The function works by tracking your heartbeat. If your heart stops beating -due to cardiac arrest, airways or circulatory failure, overdose or poisoning -your watch will automatically switch on more precise infrared LEDs and search for movement data.

If the clock determines that you do not react, it starts a countdown and audio alarm. If you still do not answer, the clock will be called up to emergency services with your LTE or telephone connection, inform you that you have no pulse and share your location.

According to Google, the watch can recognize the difference between an actual heart event and the user who simply deprives the watch.

Safety functions such as autumn recognition and crash recognition are not new, but they are not at the level of this (which is why it first needs the FDA release). Other watches have a heartbeat tracking, but they pursue much less frequently than the Pixel 3.. The Apple clock, for example, follows every 3 to 7 minutes by default.

Google worked with cardiologists

In conversation with The Verge in August, Sandaich, Senior Director of Product Management at Pixel Wearables, explained that the impulse detection is a combination of pulse, heartbeat, contact with skin and “a number of other things like movement”.

To develop the function, Google worked with cardiologists to find out what a pulse loss on Watch Insights looks like. This data was used to create an AI algorithm, which was then tested by a hundreds of thousands of real user data by a diverse group of people. Google then used stunt actors who wore tourniquets who artificially create a shortage of pulse, and simulated the types of storms that a person would suddenly imitate to lose their pulse.

The impulse detection should be available in the United States by the end of March and will arrive via an update.
