IONM Alert
Neurophysiology Safety Standards
Motor (MEP) Amplitude
Reflects corticospinal tract integrity.
Sensory (SSEP) Amplitude
Sensory (SSEP) Latency
Systemic Factors
Rule out systemic causes before surgical maneuvers:
1. MAP < 80 mmHg
2. Anesthetic bolus (Propofol/Fentanyl)
3. Hypothermia or Anemia
Guidelines for iatrogenic injury prevention.
Pulse Signal Probe
Input significant electrophysiological waveform changes across MEP and SSEP modalities to determine if surgical safety thresholds have been breached.
