Abstract
In an electronic blood pressure meter for measuring blood pressure from a finger, there is provided a photoelectric sensor including a light emitting element and a light receiving element for detecting pulse wave components from a finger placed in a cuff. Since the variation of the DC component of the pulse wave from one person to another may exceed the linear range of pulse wave measurement, the brightness level of the light emitting element is adjusted according to the level of the DC component contained in the output from the light receiving element. Thereby, favorable extraction of the variational component of the pulse wave is made always within an accurate range of pulse wave measurement.
