Abstract:
1. A method of measuring and displaying the blood pressure of a patient using a non-invasive blood pressure (NIBP) monitor having an inflatable and deflatable blood pressure cuff, a central processor, and a pressure transducer, the method comprising the steps of: obtaining a plurality of oscillometric data values from the pressure transducer; processing the oscillometric data values with the central processor that uses a first processing technique to construct a first oscillometric envelope; processing the oscillometric data values with the central processor that uses a second processing technique separate from the first processing technique to construct a second oscillometric envelope; determining with the central processor a signal quality value for the first and second oscillometric envelopes with the central processor; calculating, with the central processor, the blood pressure from the first and second oscillometric envelopes based on the signal quality value; and displaying the calculated blood pressure.
