<p>An electronic manometer for determining blood pressure based on the pulse wave amplitude change waveform formed by the change of the amplitude of pulse wave and on the change of the cuff pressure, in which a first point is determined by measuring the pulse wave amplitude and cuff pressure of when the pulse wave exceeds a first threshold, a second point is determined by measuring the pulse wave amplitude and cuff pressure of when the pulse wave exceeds a second threshold, then a pulse wave amplitude linear expression connecting the first and second points is determined, and the maximum pressure is calculated according to the pulse wave amplitude linear expression. Such an electronic manometer can accurately measure blood pressure even if, when the manometer is a type of which the cuff is worn around a wrist of the subject, the pulse wave amplitude varies depending on the state in which the cuff is worn, or even if the pulse wave fluctuates to some extent depending on the condition of the subject.</p> |
