METHOD AND SYSTEM FOR MEASURING THE INDICATOR OF THE CURRENT PERIPHERAL RESISTANCE Russian patent published in 2021 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: method for measuring the indicator of the current peripheral resistance includes: obtaining an ultrasound image of a segment of an arterial vessel; identifying a control volume in the image; obtaining a time series indicating the blood flow rate or the rate signal in the control volume and the cardiac cycle. The method comprises the stages of: calculating a first area equal to the area assembled by the rate signal between the measurement related to the beginning of the systole of the cardiac cycle and the measurement related to the moment of the systolic peak, using a processor; calculating a second area assembled by the rate signal between the measurement related to the moment of the systolic peak of the cardiac cycle and the measurement related to the end of the diastole, using a processor; and calculating the ratio between the second area and the first area, determining the indicator of the current peripheral resistance. The system for measuring the indicator of the current peripheral resistance comprises: an ultrasonic duplex scanning apparatus; an input apparatus; a processor or a computer. The set for obtaining the indicator of the current peripheral resistance comprises: an injection solution containing papaverine; an instrument for administration of the solution by means of an injection; and a system for measuring the indicator of the current peripheral resistance.

EFFECT: provides a possibility of predicting the growth of a possibly existing atherosclerotic plaque or a plaque in arterial sections currently not subject to blockage.
