Abstract：
Chronic Obstructive Pulmonary Disease (COPD) is a prevalent condition that poses a significant burden on individuals and society due to its high morbidity and mortality rates. The diaphragm is the main respiratory muscle, its function has a direct impact on the quality of life and prognosis of COPD patients. This article aims to review the structural measurement and functional evaluation methods through the use of diaphragmatic ultrasound and relevant research on its application in clinical practice for COPD patients. Thus, it serves to provide valuable insights for clinical monitoring of diaphragm function in COPD patients, facilitating early clinical intervention and aiding in the recovery of diaphragm function.
摘要：
慢性阻塞性肺疾病（COPD）是一种普遍存在的疾病，由于其高发病率和死亡率，给个人和社会带来了巨大的负担。膈肌是主要的呼吸肌，其功能直接影响COPD患者的生活质量和预后。本文旨在通过使用膈肌超声及其在COPD患者临床实践中的应用，对其结构测量和功能评估方法进行综述。因此，它可以为COPD患者膈肌功能的临床监测提供有价值的见解，促进早期临床干预和帮助恢复膈肌功能。
