How hospitals are using AI to save their sickest patients and curb 'alarm fatigue'

From interpreting CT scans to diagnosing eye disease, artificial intelligence is taking on medical tasks once reserved for only highly trained medical specialists — and in many cases outperforming its human counterparts.

Doctors who have used the new systems say AI may be better at responding to the vast trove of medical data collected from ICU patients — and may help save patients who are teetering between life and death.

From 2012 to 2014, researchers tested a “smart” electronic medical record system — sort of a precursor to true AI — across 15 ICUs in the U.S. and found that it radically transformed them.

The death rate fell more than 12 percent, meaning patients whose treatment involved the system were 58 percent less likely to die in the ICU.

For the most part, medical AI systems are designed to sit quietly in the background of the hospitals' computer systems, diligently tracking vital sign monitors and then sending doctors a text message or other notification at the first sign of trouble.

'We're at a point of being able to predict the likelihood of a cardiac arrest in 70 percent of occasions, five minutes before the event occurs,' Laussen said, adding that Toronto's Hospital for Sick Children should have an AI system for heart attack prediction up and running within the next two years.

Christopher Barton, an emergency medicine doctor at the University of California-San Francisco Medical Center who has championed the hospital's AI initiative, said that in addition to improving medical care for patients, AI systems make life in the ICU less chaotic for doctors and nurses.

As a bonus, AI models can hunt for meaningful patterns among massive databases of electronic medical records — absorbing far more data than a human would ever be able to review.

Intelligent control of high energy efficient two-stage battery charger topology for electric vehicles

The energy efficiency of the battery charging system directly affects the distance which electric vehicles can get with per charge process.

In the first stage, for low harmonics of input current, high power factor and high efficiency, the average current mode controlled ac/dc boost power factor (pf) correction method constructed and analyzed with 98% efficiency and the power factor is achieved higher than 0.99.
