MONITORING
Overview
The BISx pod provides a Bispectral Index
™
(BIS
™
) number that represents the
patient’s level of consciousness. The BIS number may be used as an aid in monitoring
the effects of certain anesthetic agents. Use of BIS monitoring to help guide anesthetic
administration may be associated with the reduction of the incidence of awareness
with recall in adults during general anesthesia and sedation.
The pod uses a sensor on the patient’s forehead to collect the patient’s EEG. BIS
monitoring translates the EEG into a single number representing the patient’s level of
consciousness. A BIS value of 100 indicates that the patient is awake. A BIS value of
0 indicates a flatline EEG.. This number may be used as an aid to the clinician in
monitoring the effects of certain anesthetic or sedative agents. Use of BIS monitoring
to help guide anesthetic administration may be associated with the reduction of the
incidence of awareness with recall during general anesthesia and sedation.
Precautions
Refer to the “Safety Considerations” section starting on page 6, at the beginning of these
Instructions for Use, for general precautions regarding safe device operation.
CAUTION:
Use clinical judgment in conjunction with other clinical vital signs to interpret
BIS values. Reliance on BIS values alone for intraoperative anesthetic or
sedative management is not recommended.
Due to limited clinical experience, BIS values should be interpreted cautiously
in patients with known neurological disorders, those taking psychoactive
medications, and in children below the age of one.
Artifact and poor signal quality may lead to inappropriate BIS values. Potential
artifact 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.
The impedance checking signal from the BISx pod may interfere with other
devices (for example, evoked potential monitors).
