Accuracy And Precision Study Of Commonly Used Non-Invasive Blood Pressure Monitors, Using A Simulator Device As A Reference

With the progressive abandon of traditional medical equipment containing mercury, automatic electronic sphygmomanometers (NIBP measurers) are being purchased instead of traditional sphygmomanometers, however the difference in the quality of performance (accuracy and precision) comes in question. In this paper we compare the performance of an electronic automatic NIBP measurer sold commonly in the market in contrast with a NIBP measurer module integrated in a multi-parameter monitor. Our study showed that, as expected, there was a difference between the performance of these two types of devices, but also allowed to characterize these differences showing interesting and not so obvious behaviour in the estimation of Systolic and Diastolic pressures of these devices.
