EXPANDING OF INTELLECTUAL POSSIBILITIES OF DIGITAL TONOMETERS FOR HOME USING

The article shows that the modern intelligent information technologies can implement a number of important additional functions for improving the efficiency of digital blood pressure monitors for home use.

It has been shown that directly in the process of the oscillometric method for determining blood pressure, home tonometers can provide the user an integrated assessment of the arterial stiffness index, which provides important diagnostic information about the complex of risk factors for cardiovascular diseases.

An approach has been proposed that allows us to assess the long-term variability of blood pressure indicators for self-measurement at home between visits to the doctor, which increases the reliability of decisions by eliminating the so-called “white medical gown” effect.

It is shown that for the practical implementation of the proposed approach, it is sufficient to use the recurrence formulas for each current measurement to correct the range of recorded values, clarify the mean and standard deviation, calculate the Pearson coefficient of variation and the index characterizing the percentage of measurements that exceed the established medical norms. Such calculations can easily be implemented on the internal processor of a home blood pressure monitor.
