METHOD FOR ARTERIAL PRESSURE MEASUREMENT Russian patent published in 2012 - IPC A61B5/22 

FIELD: medicine.

SUBSTANCE: invention is referred to the area of medicine, namely to physiology and cardiology. The registration and analysis of arterial vessels oscillograms is performed in the frequency range from 0-0.1 Hz to 40-60 Hz in process of pressure increase in blood pressure cuff with subsequent electric transformation. The compression of blood pressure cuff is continued until the moment of OSG waves appearance. The diastolic and systolic pressure is determined by the pressure in the blood pressure cuff. The limit value of range and time constant is determined during that. In order to determine the systolic pressure in the systolic part of oscillogram the current range in the first moment of time is registered and the second range is measured in divisible time moment from the initial time value. Two range values and time moments are used to detect the limit value of amplitude and time constant, and then by analogy the diastolic pressure is measured.

EFFECT: increased accuracy of arterial pressure which is reached due to performance of approximation using exponential law.
