ABSTRACT:
Blood pressure measuring method and an apparatus applicable therefor, wherein a graph indicating the relation between pressure in a cuff which is variable in the measurement process and magnitude of pulse waves generated from a part of a human body under the pressure of the cuff is described, and a mark is given for indicating the cuff pressure at a blood pressure measuring point on to the graph, for allowing judgement whether the measured data are appropriate or not by comparison of the distribution condition of the magnitude of the pulse waves and the position of the mark. Even when noises difficult to be discriminated in the circuit only should be mingled into the pulse waves so as to automatically proceed the measurement, the erroneous measurement caused by the noises can be judged by the above comparison so that the error data can be excluded or cancelled.
