초록
In this study, we conducted a brief review of 254 studies on blood pressure estimation using photopleth- ysmography (PPG). The analysis revealed a growing trend in research on blood pressure prediction using PPG. Ini- tially, simple methods like regression analysis were commonly used, but recent studies predominantly employ deep learning techniques. Additionally, many studies use other signals in conjunction with PPG for blood pressure esti- mation. There were numerous cases where PPG signals were measured using wearable devices or custom hardware, and a significant number of studies utilized publicly available datasets. The features used in blood pressure prediction were classified into six categories for analysis, and it was found that the combination of two feature categories was the most common approach. Overall, Temporal features were the most frequently used. Based on these findings, it is suggested that future research on blood pressure estimation using PPG should carefully consider factors such as signal characteristics, preprocessing, and feature extraction when developing models.
