Implementation of Real-Time Oscillometric Based Algorithm for Blood Pressure Measurement in Patient Monitor

As blood pressure is considered one of the most important metrics of human health, it is critical to have a device to measure blood pressure accurately and practically. Non Invasive Blood Pressure(NIBP) device is one of the solutions. To be able to perform well, NIBP devices need to be equipped with the right algorithm to measure blood pressure. One of the most popular blood pressure measurement algorithms is the oscillometric-based algorithm. This algorithm involves Oscillometric Waveform(OMW) extraction, envelope detection, and blood pressure estimation. In this paper, the authors want to develop and implement an oscillometric based algorithm for real-time NIBP measurement in a prototype patient monitor device. The algorithm will be tested in case-based and BPM-based data, and will be evaluated according to Indonesian Ministry of Health’s standard. Our test yields promising result, with errors below 5mmHg
