Abstract
An electronic blood pressure meter includes a cuff, an inflation control unit that controls a pump for outputting a fluid into the cuff so that a pressure in the cuff is increased at an inflation speed target in accordance with a driving voltage, a pressure detection unit that detects a cuff pressure signal indicating a cuff pressure, a blood pressure calculation unit that calculates a blood pressure value based on a pulse wave superimposed on the detected cuff pressure signal, and a target changing unit that varies the inflation speed target during an inflation process in which the cuff pressure begins to increase at an initial inflation speed target and continues to increase. The target changing unit varies the inflation speed target so that the driving voltage measured during the inflation process stays within a voltage range corresponding to a range in which the pump is capable of output.
