There is a new mobile device being developed that can help asthma sufferers prevent an attack. Called the Wing, the asthma sufferer attaches a palm-sized sensor into their phone and blows into it. The accompanying app measures lung volume – specifically Forced Expiratory Volume (FEV) – how much air is exhaled during a forced breath, and Peak Expiratory Flow (PEF), the rate at which a person exhales. These measurements can detect bronchial narrowing in people with asthma and other respiratory diseases. Along with the prevention of  asthma attacks, access to tracked lung measurements is also meant to help users over time better understand their triggers and manage symptoms.

The Centers for Disease Control and Prevention estimates that one in twelve people in the United States suffers from asthma. During an asthma attack  airways tighten, and the lining inside becomes inflamed resulting in less air getting in or out of the lungs. The Roman philosopher Seneca aptly described asthma as a “rehearsal for death.”

Featured currently on Indiegogo, the global crowdfunding site, the Wing device also promotes its ability to help athletes, singers and musicians track their lung volume. Read more here, and watch how it works.
