A wireless solution for intraoperative monitoring

Intraoperative neurophysiological monitoring (IONM) is a useful tool for monitoring the human nervous system during surgery. Current IONM systems use wired electrodes to record neural signals. However, these wires subject IONM waveforms to electromagnetic interference (EMI) from operating room (OR) equipment, which distorts recorded signals. A recording system that can be placed near the electrodes would reduce EMI significantly, and clear obstructions due to wires in the OR. In this work, we developed a wireless module for recording IONM signals, and demonstrated that the wireless system has improved resilience to EMI over traditional wired recording systems.
