More Information
Summary:An improved blood pressure measuring system based on oscillometric methods utilizes a pressure transducer which provides a varying cuff pressure for occluding the artery of a test subject. The cuff pressure is sampled at a suitable sampling rate to provide a consistent waveform including arterial or blood pressure pulses appearing in sequence during the period of decreasing the occluding pressure. Each blood pressure pulse superimposed upon the cuff pressure is extracted as a pulsating quantity for analyzing the characteristic behavior of such arterial pulse train in order to determine required blood pressure measurements. The pulsating quantity is defined to be an integral of each pulse which value is much larger than the height of the pulse and accordingly, represents an index more readily discernable from possible artifacts having a level in the vicinity of the height level of the pulse.
