Theoretical basics


Theoretical basics of volumetric compression oscillography. 

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).

Figure 4. Curves of the registration of the arterial pressure: 



a) by the method of straight manometry 
b) by the method of volumetric compression oscillometry of high resolution


Fig. 5 schematically depicts the formation of the oscillometric curve of arterial vessel with the pressure buildup in the sleeve with the subsequent change in the volume of the measured vessel. In consequence of which the amplitude of the pulse waves of the curves of pressure in the oscillometric curve is proportional to the cross-sectional area of vessel. As can be seen from the represented figure, the initial (diastolic) part of the volumetric compression oscillogram in proportion to pressure buildup in the sleeve displaces downward. Initially in the process of pressure buildup in the sleeve they record the graph of linear magnification in the pressure and venous- arterial oscillometric curve, then - curve of arterial pulse. At the point of the beginning of the withdrawal of curve downward the pressure in the constricting sleeve is equalized with the diastolic arterial pressure (DAD) in the vessel and in the course of time exceeds it to ever larger value, decreasing with each heart contraction the inside diameter of artery into the diastole.
