Abstract
A system and method for correcting a living subject's measured blood pressure when the living subject's actual blood pressure changes during an oscillometric blood pressure measurement detects oscillometric pressure pulse waves produced by a cardiac muscle of the living subject, measures a blood pressure of the living subject based on the amplitudes of the oscillometric pressure pulse waves, and corrects the measured blood pressure when the living subject's blood pressure changes during the blood pressure measurement. The system and method of this invention preferably determine an estimated blood pressure of the living subject, monitor the estimated blood pressure, and determine that the living subject's blood pressure changed during the blood pressure measurement when the estimated blood pressure changes by a predetermined amount during the blood pressure measurement. When the living subject's blood pressure is determined to have changed during the blood pressure measurement, the system and method of this invention display an estimated systolic blood pressure for the time at which the living subject's diastolic blood pressure was measured.
