Abstract：Objective To analyze the feasibility of body surface electrodes instead of multipair esophageal electrodes for the evaluation of neural respiratory drive in patients with COPD. Methods Diaphragm electromyo-gram(EMG)from body surface electrodes and multipair esophageal electrodes,was recorded in 29 patients with stable COPD recruited from outpatient clinic. Changes of neural respiratory drive of two kinds of electrodes during resting and maximal isocapnic ventilation (MIV) were observed before and after inhalation of bronchodilators. Results Ventilation significantly improved ,RMS-sur and RMS-eso significantly decreased after the inhalation of bronchodilators during resting and MIV. RMS-sur and RMS-eso were significantly correlated(r=0.660,P<0.01). Conclusion EMG from the surface electrodes may be a useful and noninvasive technique to evaluate neural respi-ratory drive in patients with COPD.
