  • Systems and methods for blood pressure measurement
    Patent number: 9750419
    Abstract: A method of determining a blood pressure of a patient includes determining a plurality of pressure pulses, wherein each pressure pulse of the plurality of pressure pulses comprises a profile having a maximum profile height. The method also includes determining a pulse score associated with the plurality of pressure pulses, wherein the pulse score is determined based on the profiles of the pressure pulses and the maximum profile heights. The method further includes determining that the pulse score is above a pulse score threshold, and generating, in response to determining that the pulse score is above the pulse score threshold, a pulse curve based on the maximum profile heights. The method also includes determining the blood pressure of the patient without completely occluding a blood vessel of the patient, wherein the blood pressure is determined based on a plurality of values corresponding to respective points on the pulse curve.
