摘要： It is desirable to minimize discomfort of a living body due to pressing by a blood pressure monitoring system of a type which monitors the blood pressure of the living body for a long period of time. The present invention is constituted by including pulse wave detecting device for detecting pulse waves of an arterial vessel of a living body, blood pressure measuring device for measuring an actual blood pressure of the living body, and control device for determining a relationship between the pulse waves detected by the pulse wave detecting device and the actual blood pressure measured by the blood pressure measuring device, determining blood pressures according to the thus-determined relationship and based on the pulse waves, and commanding a display to continuously display the thus-determined blood pressures thereon. In accordance with the present invention, blood pressures are determined according to the relationship between the actual blood pressure and the pulse waves, which is determined by the control device, and based on the pulse waves, and the thus determined blood pressures are continuously displayed, thereby eliminating the operation of successively obtaining measurements of the actual blood pressure by using a cuff, for example, and minimizing discomfort felt by the living body.

摘要： From a fluctuation of pulse periods of a subject continuously measured by a pulse period measuring device, a first pulse period fluctuation signal HFC.sub.RR which corresponds to a first pulse period fluctuation component produced in substantial synchronism with a respiration of the subject and a second pulse period fluctuation signal LFC.sub.RR which corresponds to a second pulse period fluctuation component having a predetermined frequency lower than a frequency of the first pulse period fluctuation component are extracted by a pulse period fluctuation signal extracting means. Then, based on a ratio (HFC.sub.RR /LFC.sub.RR) of the first pulse period fluctuation signal HFC.sub.RR to the second pulse period fluctuation signal LFC.sub.RR, an anesthetic depth of the subject is calculated by an anesthetic depth calculating means. Thus, the present apparatus can objectively or quantitatively calculate the anesthetic depth of the subject. Additionally, the apparatus can accurately measure the anesthetic depth of the subject without needing operator's skill or the like.
