Abstract:
Objective To investigate the role of resting pulm on ary function (FEV 1,FVC,VC) and diffusing capacity (D LCO) on exercise limitation in patients with chronic obstructive pulmonary disease (COPD).Methods During the period of 2002-04~12 the results of resting pulmonary function test which were and diffusing capacity test performed on 26 subjects with stable COPD were reviewed.The symptom-limited maximum exercise (S LME) were performed.Dyspnea index (DI) and oxygen consumption (V? O 2/kg) were determined with a metabolic cart during exercise.Borg Scale s (BS) was used for counting degree of exertional dyspnea which appeared during exercise.At the end of SLME,arterial blood gas analysis was performed to determi ne PaO 2max,PaCO 2max and Phmax at that time.Results In stepwise multiple regression analysis,the variables significantly contributing to V?O 2max/kg were D LCO % and FEV 1/VC.Conclusion Lung function and diffusing capacity can be importan t determinants of exercise capacity in COPD.
