Vigor has developed a game-changing, patented spirometer with no moving parts which has been clinically validated at Duke University Medical Center as (1) equivalent to "gold-standard" pulmonary function testing machines in the US and (2) meeting the internationally recognized American Thoracic Society (ATS) and European Respiratory Society (ERS) accuracy standards for pulmonary function testing. Beyond this, Vigor is developing a digital intervention incorporating evidence-based care protocols and behavioral economics principles to improve the management of respiratory disease.
