  • Mitigation of respiratory artifact in blood pressure signal using line segment smoothing
    Patent number: 5752919
    Abstract: A blood pressure monitoring apparatus which reduces the effects of respiration artifacts in the blood pressure samples prior to display by determining, for each heart beat detected in the blood pressure samples, the blood pressure at a median point of a line connecting a systolic, diastolic, or mean value for a current heart beat with a corresponding systolic, diastolic, or mean value for a heart beat N-1 heart beats prior to the current heart beat. The median blood pressure value for the current heart beat is then averaged with the blood pressure values of the median points of numerous previous heart beats to the current heart beat, and the resulting average is output to the display as indicative of the systolic, diastolic, or mean pressure for the current heart beat. This process is repeated for each heart beat, as desired, until the systolic, diastolic, and mean pressures are determined for each heart beat.
