EEG processing by the Cerebral Function Monitor (CFM)

Ann Anesthesiol Fr. 1979;20(3):170-4.


The Cerebral Function Monitor (CFM) is a machine designed to monitor EEG over long periods of time from hours to several days. It produces on a slow speed chart recorder a write-out of a processed EEG signal in parallel with a continuous measurement of electrode impedance. A description is given of the way in which the CFM processes both EEG and electrode impedance information. Some CFM applications are mentioned.
