The Anesthesia Depth (AI) Module monitors patients' cerebral functions by detecting the spontaneous rhythmic electrical activities of cerebral neuronal clusters. It accurately acquires and processes EEG and EMG signals, synchronously outputting monitoring parameters such as AI (Anesthesia Depth Index), BSI and SQI. Suitable for all age groups, it manages the consciousness level of anesthetized/sedated patients in OR and ICU, aids in optimizing anesthetic regimens, and effectively reduces the risk of intraoperative awareness. Standard electrode positioning, skin preparation and application ensure the reliability and accuracy of monitoring data.
