OSCILLOMETRICAL METHOD FOR MEASURING BLOOD PRESSURE

摘要

An oscillometric method for blood pressure measurement comprises the recording waveforms of arterial vessels in the carrier frequency during the rise of the cuff pressure in the pinch, followed by electric and graphics conversion. The oscillatory signals of arterial blood vessels are recorded and converted in the frequency series from 41 Hz to 400 Hz depending on the frequency of heart contractions. The rate of cuff pressure increasing at the beginning of the measurement is selected in the range from 1 to 10 Hg.mm per second depending on the frequencies of the heart contractions.
