1. A system for delivering anesthesia or sedation comprising an electrical system for acquiring signals from a subject in the presence of high frequency (HF) electrical interference comprising:
at least 2 electrodes adapted to be attached to a subject; and
physiological signal acquisition circuitry adapted to reject HF electrical interference, said circuitry comprising:
at least one front-end active input filter, and
an isolation barrier, and
a transmitter adapted to transmit data across the isolation barrier; and
an anesthesia or sedation drug delivery system adapted to deliver at least one anesthesia or sedation drug to the subject during surgery to reach and maintain a predetermined desired level of anesthesia or sedation using a closed-loop controller receiving output from a processor
wherein the physiological signal acquisition circuitry is further adapted to measure a level of remaining HF electrical interference across the isolation barrier and transmit measured physiological signals and the level of remaining HF electrical interference to the processor.
