Continuous Blood Pressure Estimation using Photoplethysmography

Abstract

Sphygmomanometer and stethoscope are the most widely used noninvasive method to measure blood pressure. In this work a novel method to estimate blood pressure using photoplethysmogram (PPG) is proposed. The PPG signal data was collected from an online patient database, Multiparameter Intelligent Monitoring in Intensive Care (MIMIC), developed by MIT lab. The estimated BP using the proposed method is then compared with the reference BP acquired from the same database. The estimated results are in good agreement with the reference blood pressure values.
