Abstract
Passive monitoring of bioelectric signals is made in the presence of active electrical anesthesia stimulation signal such that the bio-electric signals have interference artifacts from the active signal. The interference artifacts are determined and suppressed to produce a processed bio-electric signal from which can be derived quantitative values for evaluating the neurological state.
Claims15
An apparatus for passive monitoring of bioelectric signals in the presence of active electrical anesthesia stimulation, the apparatus comprising;
- a Neurological State Monitoring (NSM) system adapted to passively monitor bio-electrical signals;
- an Electrical Anesthesia Stimulation (EAS) system adapted to actively generate an EAS signal to potentiate anesthetic agents by brain stimulation of the person with repetitive electrical pulses,
- where the EAS signal creates EAS interference artifacts upon the monitored bio-electric signal;
- a Signal Interface Module (SIM) adapted to determine EAS signal interference artifacts in the monitored bio-electrical signal monitored by the NSM system
- where the EAS signal interference artifacts are suppressed in the detected bio-electrical signal to produce a processed bio-electrical signal that can be used to produce quantitative values for evaluating neurological state.
An method for passive monitoring of bioelectric signals in the presence of active electrical anesthesia stimulation, the method comprising;
- passively monitoring bio-electrical signals;
