  • Patent number: 7783343
    Abstract: The invention relates to a method and apparatus for monitoring the cerebral state of a subject. At least one of a first and second parameters is derived from the physiological signal data obtained from the subject, wherein the first parameter is indicative of the sum of spectral values of the physiological signal data in a first frequency band lying above high frequency EEG activity and the second parameter is indicative of the relative magnitudes of a first sum of k-th order spectral values and a second sum of n-th order spectral values. The second sum is calculated over a frequency band lying above high frequency EEG activity (k>2 and n>1). A state index is then formed, which is dependent on the at least one parameter and indicative of the cerebral state of the subject. The first and second parameters may be used in the Bispectral Index (BIS™) algorithm.

  • Patent number: 7775987
    Abstract: A blood pressure measurement system that utilizes a non-invasive blood pressure (NIBP) monitor having a blood pressure cuff and pressure transducer. The measurement system provides a plurality of separate processing techniques that each receive a plurality of oscillometric data values from the pressure transducer. Each of the processing techniques separately constructs an oscillometric envelope based upon the oscillometric data values. Based upon the plurality of separate oscillometric envelopes, the system compares the envelopes and develops a calculated blood pressure from the plurality of envelopes. The calculated blood pressure is then displayed by the NIBP system. The plurality of oscillometric envelopes can be compared and combined in different manners to calculate the patient's blood pressure from the plurality of different processing techniques.
