Extracorporeal diaphragmatic pacing therapy refers to the contraction of the diaphragm caused by functional electrical stimulation of the phrenic nerve, thereby improving diaphragm contractility, relieving diaphragm fatigue, increasing thoracic volume and expanding tidal volume, etc. Extracorporeal diaphragm pacemaker can improve respiratory function, and make diaphragm type II muscle fibers into type I muscle fibers with anti-fatigue effect through functional electrical stimulation. Increase the blood supply and energy of the diaphragm, so that the anti-fatigue effect of the diaphragm is enhanced. Treating intractable eructation, interfering with the reflex arc of abnormal excitation and contraction of phrenic nerve, thus restoring its normal contraction rhythm. It is suitable for central alveolar ventilation insufficiency, respiratory muscle paralysis caused by central lesions of the brainstem and spinal cord, nocturnal dyspnea syndrome, intractable hiccups, and chronic obstructive pulmonary disease. Patients with active tuberculosis, pleural adhesion thickening or pneumothorax are prohibited. It is recommended that patients go to a regular hospital to consult a professional doctor’s opinion.
