Patent ID: 7952425

Claim:
A system for adaptively filtering patient monitoring signals, comprising: a plurality of adaptive signal filters individually having a filtering bandwidth and filtering characteristics including at least one of, (a) cut-off frequency, (b) center frequency and (c) bandwidth programmable in response to received programming data, said plurality of adaptive signal filters being used to filter a received patient monitoring signal to provide a filtered signal; a noise detector for automatically identifying noise components in said received patient monitoring signal and generating noise data indicating different noise source frequencies are present in said received patient monitoring signal; and a filter controller, electrically coupled to said noise detector and said plurality of adaptive signal filters for providing said programming data adaptively determining said filtering characteristics and determining the number of, and individual filter bandwidth of, said plurality of adaptive signal filters to be used in filtering a plurality of bandwidths within an encompassing signal filtering bandwidth of said received patient monitoring signal to filter noise at said noise source frequencies, in response to, (a) said noise data indicating said noise source frequencies and (b) configuration data determining patient monitoring signal or noise source characteristics.
