Comparison of home blood pressure measurement devices in real conditions

Cardiovascular diseases are well known as one of the leading causes of death in developed countries. The hypertension is a significant danger and should be monitored carefully. In recent decades, auscultatory and oscillometric methods become as widely used for blood pressure measurement. In clinical practice, blood pressure measuring devices are evaluated according to validating protocols. Despite these protocols, a market with the automatic devices for home self-measurement of the blood pressure is flooded by a lot of cheap devices with doubtful accuracy.The goal of the study is to compare home blood pressure measurement devices in the real conditions and using the real signals and to show the difference between the values obtained by these devices and by the clinically validated reference device. For each device, the absolute errors of the systolic and the diastolic pressures were evaluated. The obtained results show that the measurement error of these devices could be frequently higher than 5 mmHg and it is necessary to concern with the accuracy of the devices.
