BIS™ Advance Monitor
Figure 1. BIS Range Guidelines
This chart reflects a general association between clinical state and BIS™ values.
Ranges are based on results from a multi-center study of the BIS™ monitor involving
the administration of specific anesthetic agents. BIS™ values and ranges assume that
the EEG is free of artifacts that can affect its performance. Titration of anesthetics to
BIS™ range should be dependent upon the individual goals established for each
patient. These goals and associated BIS™ ranges may vary over time and in the
context of patient status and treatment plan.
For more detailed clinical information, reference the clinical quick guide cards
supplied with your monitor. EEG data provides a real-time indication of brain status.
The EEG waveform data recorded by the system data is used to create the processed
variables BIS, SQI, SR, ST, Burst Count, SEF, MF, DSA, and ASYM. In addition, the raw
EEG data is provided as a trend waveform on the BIS™ Advance monitor home
screen.
More details about the BIS™ Advance processed variables are listed in Table 1. The
BIS™ Advance Monitor Parameters, below. For display of these variables, reference 3.9
