Abstract
Exercise-induced oxygen desaturation (EID) is related to mortality in patients with chronic obstructive pulmonary disease (COPD). We investigated: (1) the prevalence of EID; (2) the relative-weight of several physiological determinants of EID including pulmonary emphysema, and (3) the relationship of EID with certain patients' clinical characteristics. Data from 2050 COPD patients (age: 63.3 +/- 7.1years; FEV1: 48.7 +/- 15.7%pred.) were analyzed. The occurrence of EID (SpO(2)post = 30 kg/m(2)), impaired FEV1 (
