呼吸肌疲劳是呼吸衰竭的常见原因。电刺激膈神经还可促进膈肌收缩以维持通气国外大多采用植入膈神经刺激电极进行膈肌起搏。体外膈肌起搏器是近年来我国自行研制的一种无创伤性膈肌起搏装置。对健康人,体外膈肌起搏(EDP)能增强膈肌活动幅度,增加经膈压,改善通气,提高氧分压和降低 Respiratory muscle fatigue is a common cause of respiratory failure. Electro-stimulation of the phrenic nerve can also promote diaphragmatic contraction to maintain ventilation in most countries using implanted phrenic nerve stimulation electrodes for diaphragmatic pacing. In vitro diaphragmatic pacemaker is a non-invasive diaphragmatic pacemaker developed by our country in recent years. In healthy individuals, extracorporeal diaphragmatic pacing (EDP) increases diaphragmatic muscle activity, increases diaphragmatic pressure, improves ventilation, increases oxygen partial pressure, and decreases
