Blowing into this gadget could help asthma sufferers recognize the signs of an attack According to the team behind this interesting new Indiegogo campaign, nearly every death, ER visit, or hospitalization in the U.S. due to asthma is preventable. Because it can be difficult for sufferers to recognize the signs of an impending attack, an early warning system that could be carried around each day was needed. Thus they came up with Wing, a sensor that links up with a companion app on your phone to help manage and understand what asthma is doing to your body. By blowing into the Wing sensor, it measures how much air you can blow in a single second, and how fast it flows, the results of which give a picture of how your lungs are working. The app presents the data in a simple to understand traffic light system, helping asthma sufferers understand if they’re in danger of having an attack.
