Summary

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.

Detailed description

Patients with AECOPD will participate in a rehabilitation program for one week. Participants in the proposed study will be randomly divided into two intervention groups:controlgroup and EDP therapy group. Before using EDP,the investigators will measure the relevant parameters of lung volume , diaphragm electromyogram, diaphragm activity and other basline index. Then EDP will be applied to investigate the effects of EDP on the above mentioned respiratory mechanics parameters.

Conditions

• Acute Exacerbation of Chronic Obstructive Pulmonary Disease

Interventions

Type	Name	Description
DEVICE	control group	No EDP treatment
DEVICE	EDP	Turn on the device, and clean the skin where the patch will be located according to the screen tip. Paste the two groups of small electrodes to the inferior 1/3 of the outer edge of bilateral sternocleidomastoid, and the large electrodes are pasted to the corresponding 2nd intercostal skin surface of pectoralis major at midclavicular line.Adjusting the stimulus intensity according to the daily maximum tolerance (patients with no pain and tension).30 minutes continuous stimulation each time, twice a day, a total of one weeks of treatment .
