The BISx is intended for use under the direct supervision of a licensed healthcare practitioner or by personnel trained in their proper use. The BISx, 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 BISx 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.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
