    • 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.
    • 确定患者的血压的方法包括确定多个压力脉冲,其中多个压力脉冲的每个压力脉冲包括具有最大轮廓高度的轮廓。 该方法还包括确定与多个压力脉冲相关联的脉搏评分,其中基于压力脉冲的轮廓和最大轮廓高度来确定脉搏分数。 所述方法还包括确定所述脉搏得分高于脉搏评分阈值,并且响应于确定所述脉搏得分高于脉搏得分阈值,产生基于最大轮廓高度的脉冲曲线。 该方法还包括确定患者的血压而不完全闭塞患者的血管,其中基于对应于脉搏曲线上的各个点的多个值来确定血压。
