Hyperinflated lungs can be caused …
WebAug 20, 2015 · Static hyperinflation is due to the reduced elastic recoil of the lung. Dynamic hyperinflation (DH), which occurs independently or in addition to static hyperinflation, refers to the increase of lung volumes above their resting value that occurs with increases in respiratory rate due to expiratory flow limitation.
