A biological data observation apparatus includes a measuring unit (26) including at least a photoelectric sensor (26) including a light emitting element (26A) for emitting light with a predetermined wavelength onto a blood vessel of a subject (5) and a light detecting element (26B) for detecting, as a photoelectric volume pulse wave, a change in an amount of transmitted or reflected light resulting from the light emitted from the light emitting element (26A), a storage area (13) in which pressure conversion data correlating a pulse wave area and a blood pressure value in order that the pulse wave area may be converted to the blood pressure value as an absolute value, the pulse wave area being obtained by integrating a waveform of the photoelectric volume pulse wave per heartbeat, an operational unit calculating the pulse wave area on the basis of the photoelectric volume pulse wave obtained from the subject (5) and further calculating the blood pressure value of the subject on the basis of the calculated pulse wave area and the blood pressure conversion data, and a display unit (30) displaying a result of calculation performed by the operational unit (10). <IMAGE> |
