Proposing a Method to Measure NIBP Parameters using PPG Signal and Analyzing the Morphology of Oscillometric
Main Article Content
Abstract
The demand for monitoring non-invasive blood pressure (NIBP) parameters in health facilities for medical examination and treatment, specifically self-monitoring at home is significantly increasing. The measurement methods are based on many different techniques. However, the accuracy and stability of the measurement results from these techniques are still controversial. In this study, we proposed a novel method to measure the two most important parameters in NIBP measurement by combining two techniques: observing the Photoplethysmogram (PPG) signal to determine the Systolic Blood Pressure (SBP) and analyzing the changes of the morphology of oscillometric pulses to determine the Mean Arterial Pressure (MAP). The results were attained from 30 volunteers by using the proposed model and two commercial NIBP devices from iChoice and Omron for comparison. The measuring results of the proposed model have shown a good correlation and high stability of SBP, DBP (Diastolic Blood Pressure) and MAP measurements compared to the current techniques, expressed by the correlation of determination R2, the mean difference of proposed model to each commercial device, NIBPP – NIBPiC, NIBPP – NIBPO, and the mean (SD) between measurement results of volunteers.
