BARBARA-MONSERRAT RAMOS MACIAS is an academic who published a paper in 2018 entitled Insights into the effect of blood pressure and pregnancy on the PPG signal. BARBARA-MONSERRAT RAMOS MACIAS published this work as part of a team: Ramos Macias, Barbara Monserrat. Here is a description of this work: Introduction: Hypertension in pregnancy, characterized by high blood pressure, is one of the three most common causes of maternal death. Photoplethysmography (PPG) is a portable, non-invasive and low-cost technique, which might have the potential to detect hypertension in pregnancy along with measuring three vital signs: oxygen saturation, heart rate, and respiratory rate. Currently, efforts have been made to estimate blood pressure and detect hypertension with the PPG signal. Objectives: The primary objective of this study is to describe the effect of pregnancy and blood pressure on the PPG signal. Methods: We calculated the average pulse per month of gestational age from 5,072 PPG signals of normotensive women to create a visual representation of a normal pregnancy effect on the PPG morphology. We fitted a linear model using the g.
