The investigation of the pathophysiological mechanisms and potential applications of impaired ventilatory efficiency in cardiopulmonary exercise testing has received considerable attention in the field of chronic obstructive pulmonary disease (COPD) research worldwide. A growing body of evidence supports the notion that impaired ventilatory efficiency is an important indicator of exertional dyspnea, reduced exercise capacity, and mortality in patients with COPD. As a result, ventilatory efficiency is emerging as a promising therapeutic target for alleviating dyspnea in COPD patients. This review aims to provide a comprehensive summary of the research progress into impaired ventilatory efficiency in patients with COPD. The primary objective of this review is to improve the understanding of COPD patients with impaired ventilatory efficiency, with the ultimate goal of facilitating the comprehensive assessment and management of COPD.
运动心肺试验中低通气效率的相关病理生理学机制及临床应用是目前国内外慢性阻塞性肺疾病的研究热点之一，越来越多证据证明低通气效率与慢阻肺劳力性呼吸困难、运动耐量下降和死亡高风险有关。通气效率有望成为缓解慢阻肺患者呼吸困难症状的新的治疗靶点。本文就低通气效率在慢阻肺中的研究进展进行综述，以增加对低通气效率的慢阻肺患者的认识，更好地为这类患者提供综合全面的评估和管理。.
