Changes in finger plethysmograph due to caloric vestibular
TL;DR: There was a significant difference between the reaction in those under 50 years of age and those over in the rate of diminution of waves on the maximum reaction point, which was considerably consistent in the same subjects, although there were individual differences.

Blood Pressure Level and Heart Rate Detection from Photoplethysmography Signals Using DT–CWT
TL;DR: It was seen that blood pressure and heart rate estimations with a higher correlation coefficient and a lower average margin of error, heart rate and diastolic blood pressure analysis with the RF algorithm using the DT-CWT method, and systolic blood Pressure Analysis with the SVM algorithm would be more accurate.
Heart Rate Estimation During Physical Exercise Using Wrist-Type Ppg Sensors
TL;DR: An approach to automatically tune the KF based on the Expectation-Maximization (EM) algorithm, with a measurement fusion approach is developed, and the applicability of such a method is demonstrated using an open-source PPG database, as well as a developed synthetic generation tool that models PPG and accelerometer signals during pre-determined physical activities.

Extraction of Respiratory Activity from Pulse Oximeter Signals using Tunable Q-factor Wavelet Transform
TL;DR: The proposed method, based on tunable Q-factor Wavelet transform (TQWT), could become an efficient approach for extraction of surrogate respiratory activity from PPG signals, avoiding usage of additional specialized sensor for respiratory monitoring.
