ABSTRACT:
In an electronic blood pressure meter, pressurization requirement of the cuff is minimized by predicting a systolic blood pressure level from blood vessel information which may be obtained with an initial cuff pressure which is lower than the systolic blood pressure. The prediction of the systolic blood pressure may be based on a diastolic blood pressure, a maximum pulse wave amplitude value, on other pulse wave amplitude value, a cuff pressure value corresponding to the other pulse wave amplitude value and an empirically obtained parameter. Thus, since the cuff pressure is not increased any more than required, the discomfort to the subject person and the time period required for blood pressure measurement are both minimized and the accuracy of blood pressure measurement is improved.
