Abstract
An electronic blood pressure meter, comprising: a cuff adapted to be placed on a subject person; a pressurizing pump for pressurizing air inside the cuff; a vent valve for removing air from the cuff; a pressure sensor for detecting air pressure in the cuff; cardiovascular information detector for detecting cardiovascular information on the subject person from the pressure sensor and computing a parameter from the cardiovascular information; a membership function storage unit storing a plurality of membership functions using a relative pressure of the air pressure in the cuff to a blood pressure value as its input variable; a membership function selecting unit for selecting one of the membership functions corresponding to the parameter from the membership functions stored in the membership function storage unit; and a control unit for controlling operation of the electronic blood pressure meter according to the membership functions. Thus, blood pressure measurement can be completed in a very short time period, and it is also possible to detect insufficiency of initial cuff pressurization and the extent of insufficiency immediately after starting the measurement.
