膈神经以上水平损伤的四肢瘫痪患者,由于通气不足需要长期机械通气或膈肌起搏。基本成功的膈肌起搏需要能产生足够的潮气量。作者观察1例用双侧膈肌起搏器加用持续气道正压通气(continuous posi-tive airway pressure,CPAP)对产生潮气量的影响,了解以这种方式刺激时的膈肌功能。患者70岁。因第2颈椎骨齿状突骨折脱位致第2 Patients with paralyzed limbs above the phrenic nerve that suffer from insufficient ventilation require long-term mechanical ventilation or diaphragmatic pacing. Basic successful diaphragmatic pacing needs to produce enough tidal volume. The authors observed the effect of a bilateral diaphragter pacemaker with continuous posi-tive airway pressure (CPAP) on the tidal volume produced and the effects of diaphragmatic muscle stimulation in this manner. The patient is 70 years old. Due to the second cervical vertebra odontoid fracture dislocation caused by 2
