The oscillometric method, proposed in 1878 Mareyem, at present is used for measuring the arterial pressure in man on the basis of different systematic and apparatus solutions. As a result of development and improvement of the oscillometric method of measuring the arterial pressure N.N. Savitski, and then the association of Russian scientists under the management of Degtarev V.A., obtained the new method of registering the volumetric arterial oscillograms, which reflects the true processes, proceeding in the arterial vessel under the superimposed to the extremity sleeve, with the subsequent estimation it is more than 20 indices of hemodynamics. In the basis of method VCO is assumed the method of determining the dynamic change in the volume main arterial of the vessel being investigated, which is achieved by an original measuring system. This makes it possible with the high degree of authenticity to determine by calculation a whole series of the parameters of heart activity and indices of the state of vascular channel. The method of determining the indices AD via volumetric compression oscillometry of high resolution includes the registration of pulse curved blood vessels in the process of changing the pressure in the measuring sleeve, with the subsequent electrical and graphic transformation of the fluctuations of the volume of air in it. The improvement of method made it possible to record and to write the unchanged (true) curve of the fluctuations of AD in the vessel under the sleeve taking into account all components of its frequencies (from 0 Hz to 50 Hz) so that the curve proved to be practically i dentical record with straight manometry, which determines large value and significance of method (Fig.4).
