New app detects opioid overdose

Spotted: Researchers at the University of Washington have developed a phone app that monitors a person’s breathing rate and detects signs of an overdose. The algorithm for a smartphone, called Second Chance, monitors changes by sending out inaudible sound waves from the phone. The waves detect the person’s breathing rate and sends that information back to the phone. If there are no signs of breathing, or if a person’s breathing has slowed to seven breaths a minute or less, the app detects an overdose. It can monitor someone’s breathing from up to three feet away.

In tests at a supervised injection facility in Canada, the app was 90 percent accurate. It was even more successful at UW Medical Center, where the anaesthesiology teams “stimulated” overdoses in an operating room on patients. The effect of the anaesthetic mimics the symptoms of an overdose.

The team is still working on the app. There are plans to eventually include an alarm to call for help when an overdose is detected. Plans to commercialise the technology are underway with an application for approval made to the US Federal Drug Administration.

Takeaway: Opioid overdoses claim 130 lives every day in America, but they don’t have to be fatal if the person receives help in time. The Second Chance app is a good example of how technology can offer simple solutions to serious issues. Similar innovations are already being developed to tackle other health challenges, like glowing paper to detect infectious disease, and a headset to treat depression.  We expect more such breakthroughs in the future. The UK government has announced plans to invest £50 million in five new technology centres aimed at using the latest in artificial intelligence to, amongst other things, improve early diagnosis of diseases.
