An Intraoperative Neurophysiological Monitoring (IONM) job involves monitoring a patient's nervous system during surgery to help prevent neurological damage. IONM professionals use specialized equipment to assess electrical activity in the brain, spinal cord, and peripheral nerves. They work closely with surgeons, anesthesiologists, and other medical staff to provide real-time feedback on nerve function. This role requires expertise in neurophysiology, anatomy, and electrophysiology, often necessitating certification and specialized training. IONM is most commonly used in spine, brain, vascular, and orthopedic surgeries to enhance patient safety and surgical outcomes.
