研究目的:

1.同时探索相较稳定期COPD患者,PRISm阶段人群经体外膈肌起搏治疗后肺功能、膈肌形态与功能、全身炎症的改善效果。 2.EDP是否可以改善PRISm人群受损的肺功能。 3.探索使用体外膈肌起搏治疗前后保留比值受损肺功能(PRISm)状态到慢性阻塞性肺疾病(COPD)发展的互相关联性。

测量方法:

超声检查前受试者休息30分钟,受试者取平卧位,选择低频凸阵探头,置于右侧锁骨中线至右侧腋前线之间肋缘下,探头方向尽量垂直于膈肌头尾轴。采用B型超声选择取样线,定位于膈肌活动幅度最大的膈顶部,分别测量吸气末膈肌厚度与呼气末膈肌厚度,重复测量3次取平均值,并计算膈肌增厚分数(DTF)。测量平静呼吸及深吸气时的膈肌移动度,同样重复测量3次取平均值。

Measure time point of outcome:

Measure method:

Before the ultrasound examination, the subject rests for 30 minutes. The subject is placed in a supine position. A low-frequency convex array probe is selected and placed below the costal margin between the right midclavicular line and the right anterior axillary line, with the probe direction as perpendicular as possible to the craniocaudal axis of the diaphragm. In B-mode ultrasound, a sampling line is positioned at the dome of the diaphragm where the diaphragmatic excursion is greatest. The d
