Feather Sensors is a medical instrumentation company working in pulmonary medicine space on technology to advance spirometry measurement of lung functions with particular focus on those persons having asthma or COPD. The consensus of opinion is that more frequent/daily monitoring could likely reduce the severity of exacerbations, yielding fewer deaths, with less need for emergency room visits and hospitalizations. However, current technology for monitoring lung function at home requires those persons involved to follow strict protocols for collecting information. The firm's flagship product -- the FeatherTone-FOT⢠-- is designed to allow Users to breath normally during the period when the data re. their lung function is acquired making the likelyhood of regular/frequent readings far better
