Bispectral Index (BIS) Monitoring

Bispectral Index (BIS) monitoring is a medical tool used during anesthesia to assess a patient's level of consciousness. It analyzes brain wave patterns via a sensor placed on the forehead, providing a numerical score from 0 to 100. Lower scores indicate deeper sedation or unconsciousness, while higher scores suggest the patient is awake. This helps anesthesiologists adjust medication doses to ensure patients are neither under- nor over-anesthetized, promoting safety, reducing the risk of awareness during surgery, and enabling better management of anesthesia depth.
