Abstract

Deaths from high blood pressure account for nearly thirteen percent of all deaths in the world population. Elevated blood pressure is a sign that radical changes in life are needed. People need to know why there is an increase in blood pressure and to take measures to monitor and control it. The paper analysed the invasive and non-invasive blood pressure measurement techniques and methods: an overview of the dynamics of the blood flow and the flow factors is presented; the optimal method for the patient's blood pressure parameter variation monitoring was selected; an electronic blood pressure measuring system was devised and implemented. An experimental study was carried out with: a) the sensors placed on the left arm wrist artery and the left arm elbow artery. The results show the absolute error is up to 13 mm Hg. The pulse is recorded accurately with the absolute error of up to 2 beats per minute.
