Bispectral Index - StatPearls - NCBI Bookshelf
Nov 6, 2023 · The bispectral index (BIS) monitor is pivotal in this process. Maintaining BIS values within the range of 40 to 60 is essential to prevent anesthesia awareness and mitigate potential long-term psychological consequences.
Bispectral index - Wikipedia
Bispectral index monitor indicating a nearly isoelectric pattern of electroencephalographic activity. The bispectral index is a statistically based, empirically derived complex parameter. It is a weighted sum of several electroencephalographic subparameters, including a time domain, frequency domain, and high order spectral subparameters. [5]

Jul 7, 2024 · the resulting algorithm generates a bispectral index (BIS) it has been validated on healthy and now other patient populations; COMPLICATIONS. Benefits. BIS < 60 results in very low levels of post-op recall; shown to lower anaesthetic consumption; slightly quicker awaking; safe with diathermy and defibrillation; Problems
Bispectral Index - an overview | ScienceDirect Topics
The bispectral index is a statistical numeric value based on bispectral processing of the last 15 to 30 seconds of the harmonic and phase relationship of the frontal lobe EEG data. A score of 90 to 100 represents an awake state; 70 to 80, a moderate sedation state; 60 to 70, a deep sedation state; 40, general anesthesia; and 0, consistent with ...
