WebStudy Design and Methods: We retrospectively analyzed data from 2,269 tobacco-exposed participants in the Subpopulations and Intermediate Outcome Measures in COPD Study with or without COPD. We used various BDR definitions: change of ≥ 200 mL and ≥ 12% in FEV1 (FEV1-BDR), change in FVC (FVC-BDR), and change in in FEV1, FVC or both (ATS-BDR). WebThe patient does a constant level of work on a treadmill or cycle ergometer for 6 to 8 minutes at an intensity selected to produce a heart rate of 80% of predicted maximum heart rate. The FEV1 and FVC are measured before and 5, 15, and 30 minutes after exercise. Exercise-induced bronchospasm reduces FEV1 or FVC ≥ 15% after exercise. hallmark cards by mail
