Why should raw EEG be available for review during quantitative EEG monitoring?

Raw EEG should be available for review during quantitative EEG monitoring because it plays a crucial role in identifying asymmetries or focal abnormalities in brain activity. By examining the raw EEG data, a technologist or clinician can detect specific patterns that may indicate pathological changes or areas of concern within the brain. This visual assessment allows for a more accurate interpretation of the quantitative data, which relies on sophisticated algorithms and processing techniques.

The availability of raw EEG can reveal subtle variations and anomalies that quantitative measures alone may overlook. For instance, if there is a suspected lesion or irregularity in a specific brain region, closely analyzing the raw EEG can provide insights into the electrical activity there, aiding in the decision-making process during surgery.

In addition to identifying abnormalities, having immediate access to the raw data supports real-time clinical judgments and interventions, which are vital in an intraoperative setting where dynamic changes can occur rapidly. This comprehensive approach enhances the quality of monitoring and ensures patient safety, thereby making it essential for raw EEG to be readily available during quantitative EEG monitoring.
