STUDY OBJECTIVE To detect dynamic hyperinflation by comparing reduction in inspiratory capacity (IC) during both paced hyperventilation and cycle ergometry in patients with moderate-to-severe COPD, studied before and after acute bronchodilation. METHODS IC and FEV(1) were measured before and after metronome-paced hyperventilation at twice the resting respiratory rate for 20 s in 16 patients with COPD before and after 54 microg aerosolized ipratropium bromide (IB). We also studied the same 16… CONTINUE READING
