<p>&nbsp;</p><p>Google is taking its health tracking ambitions a step further with Health Guardian, a new set of features designed to spot subtle changes in the body that may not be obvious day to day. The tools are coming to the Google Health app for eligible Pixel Watch and Fitbit devices. Google says they can work quietly in the background around the clock, analysing physiological data and highlighting important changes over time.

Insulin resistance trends analyse multi-week physiological data to track changes in metabolic health without requiring a blood sample, according to Google. Blood pressure trends use pulse and movement patterns collected over time to estimate changes without requiring a traditional blood-pressure cuff. There is also sleep breathing quality, which looks at breathing patterns during sleep and shows how much of the night was spent with optimal breathing. The fourth feature is breathing emergency detection. It is designed to detect a critical drop in blood oxygen and, if the person becomes unresponsive, can automatically contact emergency services and emergency contacts.

Google's new Health Guardian features will use Pixel Watch and Fitbit data to track subtle changes in insulin resistance, blood pressure and sleep breathing. The tools provide longer-term health insights, but Google says they are for wellness and are not medical diagnostic tools.
