Computers can control Intensive care Unit ventilators more successfully than doctors, an expert in computerised medicine has told the American Association for the Advancement of Science. A computer was also found to make better medical decisions than doctors when it came to prescribing antibiotics.The Latter day Saints Hospital at Salt Lake City found that survival rates for patients with a severe form of pneumonia increased from 30 per cent to 60 per cent when the ventilators were controlled by a computer using information provided by monitoring devices.
