Abstract
Blood Pressure (BP), a vital indicator, is influenced by the pressure exerted by blood against the walls of arteries, playing a fundamental role in health assessment. A non-invasive optical method, Photoplethysmography (PPG), is utilized for measuring changes in blood volume per heartbeat, reflecting the mechanical action of the heart. Given the inherent connection between PPG signals and heart contractions, it is reasonable to investigate the potential correlation between PPG signals and blood pressure measurements. In this study, a statistical analysis is conducted with the aim of establishing the relationship between PPG signals and blood pressure. Specifically, the study focuses on Finger Mean Arterial Pressure (MAP), derived from the PPG signal, aiming to be statistically compared with various blood pressure components, including Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), and Brachial Blood Pressure. The objective of this analysis is to shed light on the potential associations and clinical relevance between PPG signals and blood pressure parameters. The estimation of SBP and DBP involved a non-real-time measurement method, requiring the consensus of two experts who resolved any disparities in their assessments. This comprehensive analysis provides a deeper understanding of the potential connections between PPG signals and blood pressure, shedding light on their interplay and clinical relevance. Brachial MAP is obtained from the oscillometric signal. The data is collected from a group of 30 healthy individuals, and Pearson's correlation coefficients are calculated to determine the associations between finger MAP and SBP, DBP, and brachial MAP. The mean differences between the systolic and diastolic measurements by the two experts are -2.63 ± 1.90 and -3.12 ± 2.51 mmHg, respectively. The correlation coefficients for finger MAP versus brachial MAP, finger MAP versus systolic pressure, and finger MAP versus diastolic pressure are 0.9820, 0.8591, and 0.7915, respectively. Based on these findings, a strong connection between finger MAP and blood pressure is suggested, offering potential opportunities to derive SBP and DBP using the PPG signal through finger MAP.
