Respiratory electrophysiological studies are useful in the investigation and monitoring of respiratory failure. Phrenic nerve conduction studies and needle electromyography of the diaphragm are invaluable in establishing the diagnosis, determining the severity, and following the progression of peripheral respiratory muscle dysfunction. In addition to these established methods, repetitive phrenic nerve stimulation is of diagnostic value in patients with neuromuscular transmission defects and dyspnea. The diagnosis of impaired central respiratory drive can often be accomplished by the newly-developed techniques of transcortical magnetic stimulation of the motor cortex with recording of the diaphragm and phrenic nerve somatosensory evoked potentials. These studies are of particular value in critically ill patients where both the central and peripheral lesions may impair respiration.
呼吸电生理研究在呼吸衰竭的调查和监测中很有用。膈神经传导研究和膈肌针极肌电图在确立诊断、确定严重程度以及跟踪周围呼吸肌功能障碍的进展方面具有重要价值。除了这些既定方法外，重复膈神经刺激对患有神经肌肉传递缺陷和呼吸困难的患者具有诊断价值。中枢呼吸驱动受损的诊断通常可通过新开发的经皮质磁刺激运动皮层并记录膈肌和膈神经体感诱发电位的技术来完成。这些研究在危重症患者中具有特殊价值，因为中枢和周围病变都可能损害呼吸。
