The Effect of EDP on Diaphragmatic Function and Neural Respiratory Drive in Patient With AECOPD

Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory disease characterized by airflow limitation that is progressive and not fully reversible. Patients with acute exacerbation of COPD must be hospitalized, as for further increase in airway resistance, pulmonary alveolar excessive expansion, diaphragm fatigue and neural respiratory drive. In recent years, Pulmonary rehabilitation is recognized as a core component in the comprehensive management of COPD, EDP as a means of rehabilitation can alleviate diaphragmatic fatigue, improve ventilation function, reduce the neural respiratory drive in patients with COPD during hospitalization, but still lack of evidence based medicine. Surface EMGdi can accurately evaluate neural respiratory drive, its detection is non-invasive, simple and safety .Therefore,Neural respiratory drive by surface EMGdi can be used as an important index for evaluating the therapeutic efficacy of AECOPD patients during hospitalization. In the present study, about 40 patients with COPD will be recruited as research subjects .And the investigators aim to explore the effect of EDP on diaphragmatic function and neural respiratory drive in patient with AECOPD.Contrast analysis will be conducted to evaluate the effects of EDP on patients with AECOPD, which may provide a reasonable basis for the clinical application of EDP to AECOPD patients.
