Cranial Nerve Monitoring

Hinweis der Redaktion

  1. CN I, II & VII are sensory only. All others have motor components.
  2. MUAP – Free Run EMG Muscle fibers range from 10 in the eye muscles to 3000 in larger muscles like the gastronemius.
  3. CMAP – Triggered EMG
  4. Typical peaks: N1, N2, N3; P1, P2, P3
  5. Rarefaction causes sudden excitation (ear drum moves away from ear).
