Background. The actuality of the research is due to the need of improving the estimation accuracy of the blood pressure values (BP) by blood pressure monitors. BP control is the most important parameter measured in various forms of hypertension. As a result of research, the hydrocuff technology of oscillations formation allows to significantly increase the amplitude of the generated oscillations. This enables the BP assessment with accuracy comparable to manual blood pressure monitors.
Materials and methods. The LabVIEW environment has been used for designing of units and blocks of the blood pressure monitor which implements the hydrocuff method of oscillations formation.
Results. The microprocessored automatic hydrocuff BP monitor, with BP error assessment which is not exceed the error of the mechanical tonometer is developed as a result of research.
Conclusions. The work has solved the task of developing of basics for hydrocuff technology of obtaining and processing the oscillations for the realization of its benefits in BP monitors. The breadboard of device has been made
with its error estimation using a modern element base.
