Abstract
In a clinical and physiological abnormality monitoring apparatus, and blood pressure monitoring apparatus detects a blood pressure abnormality and the like of a body by employing a pulse wave signal. A frequency analysis is carried out with respect to a pulse wave signal, while this pulse wave signal corresponds to time sequential data of pulse waves. As a result, both a C-frequency component indicative of a fluctuation component of a base line of the pulse wave signal, and also an A-frequency component representative of the respective pulse waves are acquired. A ratio C/A of power of a peak contained in the C-frequency component with respect to power of a peak contained in the A-frequency component is calculated to determine abnormality of the blood pressure.
