Abstract
An electronic device for measuring blood pressure, according to which either systolic pressure may be derived from mean pressure and diastolic pressure, or diastolic pressure may be derived from systolic pressure and mean pressure, whereby the time duration of the application of pressure to the patient's arm may be reduced because the pressure to be applied may only range substantially over between mean pressure and diastolic pressure or between systolic pressure and mean pressure. Additionally proposed is a means for improving the accuracy of the above-mentioned derivation of systolic pressure or diastolic pressure. As a result, considerable reduction in the time duration required for measurement may be reduced without any increase in measurement errors.
