<p>PURPOSE:To enhance the degree of certainty of blood pressure measurement to a large extent by arranging and using both a blood pressure deciding means of photoelectric pulse wave capacity vibration method and that of oscillometric method, and adopting the result of blood pressure measurement by the secondary means if blood pressure measurement by the primary means fails. CONSTITUTION:When a value of blood pressure obtained by a first blood pressure deciding means is judged to be accurate, judgement is YES and the blood pressure value is adopted and indicated on a display 13. When no accurate photoelectric pulse wave can be detected by reason of the influence of disturbing light on photoelectric pulse wave, the out-of-the-way position of a photoelectric sensor, and the like, and the result of measurement is judged to be inaccurate, i.e., failure in deciding blood pressure, then judgement is NO and the result of measurement is not adopted and the process of deciding blood pressure is executed in accordance with the information on pressure pulse wave detected by a second blood pressure deciding means; i.e., an algorithm is applied to the information on the detected pressure pulse wave so as to calculate the value of blood pressure.</p> |
