1.2. Introducing the BIS™
Complete Monitoring System
The BIS™ complete monitoring system is a user-configurable patient
monitoring system designed to monitor the hypnotic state of the brain
based on acquisition and processing of EEG signals. The BIS™ complete
Note:
Introducing the BIS™ Complete Monitoring System
12
BIS™ Complete Monitor
system processes raw EEG signals to produce a single number, called the
Bispectral Index™, or BIS, which correlates with the patient's level of
hypnosis.
The BIS Complete monitor display consists of:
• The current BIS™ number
• Raw EEG waveforms in real time
• Various signal quality indicators (EMG, SQI)
• Trend graphs of processed EEG parameters (including various
options)
• Suppression Ratio (SR, displayed upon activation by the user)
• Suppression Time (ST, a new feature, displayed upon
activation by the user, available for SW revision 3.50 and
higher)
• Alarm Indicator and Messages
• Burst Count number (when a 4-channel BIS™ system and a BIS™
bilateral sensor are in use)
The system performs self-tests to ensure that the monitor and its
components are functioning properly and that impedance levels of
patient sensors are within acceptable limits. Touch screen menus allow
the user to change the data display and review stored data.
The BIS™ system also includes a number of methods for downloading
data from the system.

Important Information about Using BIS™ Monitoring
The BIS™ EEG complete monitor system is intended for use under
the direct supervision of a licensed healthcare practitioner or by
personnel trained in its proper use. The system, and all its
associated parameters, is intended for use on adult and pediatric
patients within a hospital or medical facility providing patient care
to monitor the state of the brain by data acquisition of EEG signals.
The BIS™ index, one of the Complete Monitor output parameters,
may be used as an aid in monitoring the effects of certain anesthetic
agents; and its usage with certain anesthetic agents may be
associated with a reduction in primary anesthetic use and a
reduction in emergence and recovery time.
Use of the BIS™ index for monitoring to help guide anesthetic
administration may be associated with the reduction of incidence of
awareness with recall in adults during general anesthesia and
sedation.
BIS™ is a complex monitoring technology intended for use as an
adjunct to clinical judgment and training. Clinical judgment should
always be used when interpreting BIS™ in conjunction with other
available clinical signs. Rel iance on BI S™ alone for intraoperative anestheti c management is not recommended. As with any monitored parameter,
artifacts and poor signal quality may lead to inappropriate BIS™
values. Potential artifacts may be caused by poor skin contact (high
impedance), muscle activity or rigidity, head and body motion,
sustained eye movements, improper sensor placement and unusual
or excessive electrical interference. BIS™ values should also be
interpreted cautiously with certain anesthetic combinations, such
as those relying primarily on either ketamine or nitrous
oxide/narcotics to produce unconsciousness. Due to limited clinical
experience in the following applications, BIS values should be
interpreted cautiously in patients with known neurological
disorders and those taking other psychoactive medications.
