- The ICU BIS
Range Guidelines are included in the set of pocket cards that
accompany the A-2000 BIS XP Monitor.
- The BIS
Index is a single number, ranging from 0 to 100, and scaled to
correlate with important clinical endpoints during the administration
of sedative agents.
- Various
places within the BIS range guidelines may be ideal targeted ranges
based on different treatment goals for your patient at different
points during care.
- Awake, alert
patients will have BIS values in the 90’s. With light sedation,
the BIS will generally descend into the 70’s and 80’s.
- A BIS value
below 60 indicates an extremely low probability that the patient
will recall unpleasant events.
- BIS readings
in the 20’s and 30’s indicate very deep sedation.
- BIS values
below 20 correlate with patterns of burst suppression,
- And at a
reading of zero, with an isoelectric EEG.
