Biospectral Index or BIS monitoring is a new way of measuring how 'asleep' or sedated a patient is in the Operating room or in the ICU.
Example monitor
This machine picks up the electrical patterns of the brain from a band that goes across the patient's head. This information is translated to a number that indicates the patient's level of awareness.
Sometimes patients may need treatment where they should not move and deep sedation is required. This machine allows the Intensive Care staff to give special drugs to make sure the patient is kept fully sedated or is able to rest comfortably between medical and nursing treatments.
All Intensive Care interventions and procedures carry a degree of potential risk even when performed by skilled and experienced staff. Please discuss these issues with the medical and nursing staff who are caring for the patient.
Of course, if you have any questions or concerns, please discuss them with the ICU nurses and doctors.
