СПОСОБ ИЗМЕРЕНИЯ АРТЕРИАЛЬНОГО ДАВЛЕНИЯ

摘要

FIELD: medicine. ^ SUBSTANCE: method involves compressing artery in extremity through bulk of soft tissues with variable compensating pressure and fixing pressure in soft tissues, determining time intervals in which derivative of the pressure in soft tissues is equal to zero. The compensating pressure is changed discretely in time with delay after determining each time interval beginning and at time moment coinciding with each interval end. Arterial blood pressure value is determined as a set of discrete values of pressure in soft tissues fixed on determined time interval boundaries. Initial value of the compensating pressure is selected to be less than arterial blood pressure and time discretization step is not to be less than half of cardiac cycle duration. ^ EFFECT: applicability for creating digital tonometers measuring arterial blood pressure within shorter time period and under more comfortable conditions for a patient. ^ 12 dwg
