Patients with chronic obstructive pulmonary disease have abnormal respiratory mechanics, respiratory muscle function, gas exchange, and cardiovascular function during exercise. Their impaired exercise tolerance is at least partly due to altered respiratory mechanics, but factors that increase ventilation during exercise indirectly contribute to exercise limitation. Clinical exercise testing is a very important tool in the assessment of exercise capacity, assessment of factors that contribute to exercise limitation, and differential diagnosis of cardiopulmonary disease.
慢性阻塞性肺疾病患者在运动期间存在呼吸力学、呼吸肌功能、气体交换及心血管功能异常。其运动耐力受损至少部分归因于呼吸力学改变，但运动期间增加通气的因素也间接导致运动受限。临床运动测试是评估运动能力、导致运动受限的因素以及心肺疾病鉴别诊断的重要工具。
