BURST SUPPRESSION MONITOR FOR INDUCED COMA
First Claim
Patent Images
1. A method of maintaining a subject at a desired state of sedation using a logic processor comprising:
- receiving digital data representing said subject'"'"'s EEG at said processor;
using said processor to determine one or more burst onsets;
using said processor to determine one or more suppression onsets;
using said processor to determine one or more interburst OR burst suppression intervals by comparing one or more burst onsets to one or more suppression onsets;
using said processor to determine a mean burst suppression (BS) interval for a specified time length wherein said BS interval indicates time between burst onsets, regardless of burst duration;
using said mean burst suppression (BS) interval to adjust therapy to said subject to maintain said desired state of sedation.
