While at the CDC, Van Sickle tried to track asthma outbreaks by getting hospital emergency room statistics about asthma treatments, but the key piece of information -- figuring out where the attacks began -- remained a mystery. The goal of the Madison project is to learn something about asthma exposures, but it also is helping individuals better understand what triggers their own symptoms. "We had this one guy who was using his inhaler every day at work, and he was fine the rest of the time. He had never put it together that he had workplace-related asthma. It's funny what people miss when they're so close to stuff," Van Sickle said. GPS-endowed medical devices are a new but growing part of GPS applications, according to Oregon-based Glen Gibbons, who has been tracking the industry since 1989. "There's a system being developed to track Alzheimer patients and one that can track when someone takes a fall," he said. Related Links: |
