Blood pressure monitor apparatus

A blood pressure monitor apparatus for monitoring a blood pressure of a living subject, comprising:

• pulse-wave-propagation-velocity-relating information obtaining means for successively obtaining pulse-wave-propagation-velocity-relating information which relates to a pulse-wave propagation velocity at which a pulse wave propagates in an artery of the subject;
• pulse-period-relating information obtaining means for successively obtaining pulse-period-relating information which relates to a pulse period of the subject;
• peripheral-blood-volume-relating information obtaining means for successively obtaining peripheral-blood-volume-relating information which relates to a volume of blood which flows in a peripheral body portion of the subject;
• and
• abnormality judging means for judging that said blood pressure of the subject is abnormal when at least one of said pulse-wave-propagation-velocity-relating information, and pulse-period-relating information, and said peripheral-blood-volume-relating information does not fall within a corresponding one of a first, a second and a third reference range,
• wherein said first, second, and third reference ranges have a first, a second, and a third lower limit value, respectively each of said first, second, and third lower limit values being a common value.
