Measuring of arterial pressure by volumetric compressive osvillometry method have shown, that in case of measuring by the auscultative method (AM) errors with high reliability reach tens of millimeters of mercury. As a result, misdiagnoses are taking place, wrong medications for blood pressure decrease are prescribed in case of its low values. As a result, a large number of examined patients have complications due to disorder of blood circulation in vitally important organs, threatening their health and life. Aim of the research. Development of a scientifically grounded method for measuring blood pressure and determination of the degree of divergence of the obtained data with AM, as well as an assessment of the risks arising from the use of AM in medical practice. Material and methods. In a multicenter BP study measured by means of AM, were examined 1,086 persons, 495 residents of Novokhopersky district of the Voronezh region were added to them. At the same time another group of physicians registered blood pressure by the method of volumetric compression oscillometry (VCO). Results. The first registrations have shown, that there are significant differences between the contour of volumetric oscillograms recorded in practically healthy people and patients with isolated systolic arterial hypertension (ISAH) and hypertensive disease (HD). Healthy persons have the amplitude of the oscillations decreased after reaching the pressure in the cuff of the brachial artery value of AD med.; in patients with ISAH and HD – in most cases that value increases. The conclusion. The results of the performed study show that physicians, following the definition of blood pressure by the Korotkov method, make mistakes in the diagnosis and prescription of medicaments, often putting at risk health and life of elderly examined patients.
