Clinical Trial[Ventilatory response at maximal exercise in patients with chronic obstructive pulmonary disease].
To compare the difference in the ventilatory equivalent for carbon dioxide (EqCO(2)) between the patients with chronic obstructive pulmonary disease (COPD) and normal adults at maximal exercise, and to identify the factors inducing the abnormal change of EqCO(2) in COPD patients. ⋯ Increased V(D)/V(T) may play an important role causing increase in EqCO(2) during exercise in patients with COPD.
