What should the impedance levels be monitored for during a surgical procedure?

Monitoring impedance levels during a surgical procedure is critical to ensure optimal grounding. Proper grounding minimizes the risk of electrical interference and helps to establish a stable baseline for the neurophysiologic data being collected. High impedance levels can indicate poor connections, which may lead to increased noise and inaccurate readings of the neural signals. This can adversely affect the monitoring process and potentially compromise patient safety. Ensuring optimal grounding contributes directly to the reliability of the data obtained, facilitating effective intraoperative monitoring and allowing for timely interventions if necessary. Thus, maintaining appropriate impedance levels is fundamental to achieving predictable and accurate neurophysiologic measurements during surgery.
