ABSTRACT:
An apparatus for automatically measuring a blood pressure of a subject, including a pressing device for pressing a body portion of the subject, such as an upper arm; a first blood pressure measuring device for detecting pulse sounds which are produced from the body portion as the pressing force of the pressing device is varied, and determining a first blood pressure (BP) value of the subject based on at least one of an appearance and a disappearance of the pulse sounds; a second blood pressure measuring device for detecting an oscillatory pressure wave which is produced from the body portion in synchronization with heartbeat of the subject as the pressing force of the pressing device is varied, and determining a second BP value of the subject based on variation in magnitude of the oscillatory pressure wave; and a judging device for judging at least one of the first and second blood pressures to be abnormal if a degree of inequality between the first and second blood pressures exceeds a reference value.
