摘要: The objective of this study was to investigate whether some activities daily living (ADLs) usually related dyspnea sensation in patients with chronic obstructive pulmonary disease (COPD) are associated dynamic lung hyperinflation (DH) and the use simple energy conservation techniques (ECTs) might reduce possible hyperinflation. Eighteen (mean age: 65.8 ± 9.8 years) moderate-to-severe COPD performed six ADLs (walking on a treadmill, storing pots, walking 56 meters carrying 5-kilogram weight, climbing stairs, simulating taking shower, putting shoes) had their inspiratory capacity (IC) measured before after each task. were moderately obstructed forced expiratory volume 1 second (FEV1): 1.4 0.4 L (50% 12.4); FEV1/forced vital capacity: 8.1; residual volume/total 52.7 10.2, reduction IC seen all (p < 0.05): (1) going upstairs, 170 mL; (2) 5 kil...
