The feature, also coming to the Pixel Watch 4, is currently available only in some European countries and has not been cleared by the U.S. Food and Drug Administration, with no U.S. release date announced. Google says it could assist during severe pneumonia, accidental drug overdose, or choking, but experts like Dr. Lindsey Rosman of the University of North Carolina School of Medicine warn it may increase health anxiety.", "body_md": "A new feature on the [Pixel Watch 5](https://www.cnet.com/tech/mobile/google-pixel-watch-5-hands-on/) isn’t designed to give users additional routine health data. Instead, it’s intended to help them when they’re unable to help themselves.\n\nGoogle’s newly announced breathing emergency detection feature uses AI to analyze signals from the watch’s heart rate, motion and altitude sensors to detect signs of a breathing emergency. If it detects one, the wearer has 30 seconds to cancel the alert before the watch automatically calls emergency services and alerts their emergency contacts.\n\nGoogle says the feature could provide life-saving assistance during incidents such as severe pneumonia, an accidental drug overdose, or choking. In addition to the Pixel Watch 5, the feature will also be available on the [Pixel Watch 4](http://I Tested the Pixel Watch 4: Design and Function, Working in Harmony) when the feature rolls out.\n\nBut Americans will have to wait. The feature has not yet been cleared or evaluated by the Food and Drug Administration and is currently only available in some European countries. A US release date has not yet been announced.\n\n## How the breathing emergency detection works\n\nThe feature combines data from sensors in the watch and an AI-based algorithm.\n\n“The optical sensor uses green, red and infrared light to estimate blood oxygen levels and identify severe, persistent drops,” Pramod Rudrapatna, Google senior product manager for health, told CNET in an email. “The accelerometer looks for prolonged low movement, while the barometer helps account for environmental factors such as high altitude, where oxygen saturation can naturally be lower. These signals are analyzed together by on-device machine learning models to determine whether they are consistent with a potential breathing emergency while minimizing false alerts.”\n\nTo reduce false positives, [Google says](https://blog.google/products-and-platforms/devices/pixel/pixel-watch-breathing-emergency-detection/) the feature will also ensure the wearer hasn’t been asleep for more than 30 minutes during the detected incident so that conditions such as sleep apnea won’t interfere with the readings.\n\n“That combination is a smart way to cut down false alarms,” says [Dr. Lindsey Rosman](https://www.med.unc.edu/medicine/cardiology/people/lindsey-a-rosman-phd/), assistant professor of medicine in the division of cardiology at the University of North Carolina School of Medicine. She adds that photoplethysmography (or PPG, the light sensors often found in wearables) has known limitations that can affect readings, but “requiring stillness alongside the oxygen drop likely helps reduce these issues [and] improves reliability.”\n\nRosman, who also studies the psychological impacts of cardiac wearables, warns that alerting people to a life-threatening event they can’t independently verify is a double-edged sword.\n\n“It can save lives, but it may also drive real health anxiety and hypervigilance, even when the alert is a false positive,” she said.\n\nIf users don’t want to use this feature, they can turn it off in their settings.\n\nBreathing emergency detection is one of four new features that come under the Pixel’s Health Guardian umbrella. The other three monitor trends for insulin resistance, blood pressure, and sleep breathing quality.\n\nIn 2025, Google rolled out a feature called [loss of pulse detection](https://www.cnet.com/health/medical/loss-of-pulse-detection-alerts-on-the-pixel-watch-3-are-finally-here/) on the [Pixel 3 Watch](https://www.cnet.com/tech/mobile/google-pixel-watch-3-review-still-my-favorite-android-watch/) in the US. That feature tracks the wearer’s pulse, while breathing emergency detection focuses on blood oxygen levels and patterns. However, if they work as promised, both features could work together to detect the same type of health emergency, such as an accidental overdose. Loss of pulse detection has been cleared by the FDA and is available now.", "url": "https://wpnews.pro/news/pixel-watch-5-will-call-emergency-services-if-it-detects-a-breathing-emergency", "canonical_source": "https://www.cnet.com/health/medical/pixel-watch-5-will-call-emergency-services-if-it-detects-a-breathing-emergency/", "published_at": "2026-08-13 21:51:01+00:00", "updated_at": "2026-08-13 22:35:01.427709+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-ethics"], "entities": ["Google", "Pixel Watch 5", "Pixel Watch 4", "Food and Drug Administration", "Pramod Rudrapatna", "Dr. Lindsey Rosman", "University of North Carolina School of Medicine", "CNET"], "alternates": {"html": "https://wpnews.pro/news/pixel-watch-5-will-call-emergency-services-if-it-detects-a-breathing-emergency", "markdown": "https://wpnews.pro/news/pixel-watch-5-will-call-emergency-services-if-it-detects-a-breathing-emergency.md", "text": "https://wpnews.pro/news/pixel-watch-5-will-call-emergency-services-if-it-detects-a-breathing-emergency.txt", "jsonld": "https://wpnews.pro/news/pixel-watch-5-will-call-emergency-services-if-it-detects-a-breathing-emergency.jsonld"}}
