Abstract:
Objective To evaluate the effect of inhaling Ipratropium bromide to patients with chronic obstructive pulmo- nary disease(COPD)on resting pulmonary function,ventilation and exercise capacity during exercise.Methods All 12 stable patients were diagnosed as COPD.Before and after inhaling single-dose lpratropium bromideis,resting pul- monary function and Symptom-limited progressive cycle ergometer exercise tests were proceed.Results No obvious change in resting pulmouary function after inhaling Ipratropium bromide solution of four times the standard dose,but the maximal rate of work,maximal oxygen uptake,the maximal volume of ventilation per minute and the maximal ratio of tidal volume to inspiratory capacity increase significantly.The maximal dead space/tidal volume ratio and the maximal ventilatory equivalent for CO_2 have no change.There is a significant correlation between the amount of the maximal ratio of tidal volume to inspiratory capacity improved and amount of maximal oxygen uptake improved(r=0.598,P
