ABSTRACT:
An electronic sphygmomanometer employing both the Korotkoff method and the oscillometric method which is thereby capable of accurately measuring blood pressure due to the two advantages of the above-described two methods. The electronic sphygmomanometer is arranged in such a manner that either of the results of measurements of the two methods can be automatically selected. A gate for detecting the Korotkoff sound by using an oscillation in cuff pressure is automatically stopped, and that the validity of the Korotkoff sound is determined in accordance with a change in the height of the oscillating pulse wave.
