Bispectral Index Monitor
The Bispectral Index Monitor (BIS) is a device used during surgery or sedation to assess a patient's level of consciousness. It analyzes brain activity through electrodes placed on the forehead, providing a numerical score that reflects how deeply a person is sedated. A lower score indicates deeper sedation, while a higher score suggests higher awareness. This helps anesthesiologists ensure that patients receive the right amount of anesthesia, avoiding both under-sedation, which can cause discomfort, and over-sedation, which can lead to complications. The BIS monitor enhances patient safety during procedures requiring anesthesia.
