Abstract: The incidence of spinal cord injury is becoming higher and higher, of which more than half are cervical spinal injury. The main cause of death in high cervical spinal injury is respiratory function failure. The patients who survived must rely on ventilators to sustain life. In view of the shortcomings of ventilators, many researchers tried to use diaphragm pacing technology instead of ventilator to reconstruct the function of respiratory. This article introduced the application of diaphragm pacing technology in patients with cervical spinal injury.
