ABSTRACT:
An electronic blood pressure meter, equipped with the functions of computing at least a single relative pulse wave amplitude value in relation with a maximum pulse wave amplitude value, computing a blood pressure value from the cuff pressure when an amplitude of the pulse wave signal has coincided with the relative amplitude value during a change in the amplitude value of the pulse wave signal, and using the reference pressure value thus obtained in accordance with a certain arithmetic formula. If desired, a different process may be selected for determining a blood pressure depending on an initial cuff pressure. This electronic blood pressure allows a measurement to be completed in a very short time and minimizes the discomfort of the person whose blood pressure is to measured through reduction of the maximum cuff pressure. Yet the mathematical formula can be reduced to a simple arithmetic algorithm and is therefore easy to implement.
