Abstract: We describe an evaluation of photoplethysmography (PPG) signals with two wavelengths channels (infrared and red) using a wrist-worn sensor for the estimation of heart rate variability (HRV) ...

Abstract: Pulse oximetry is a popular non-invasive method for monitoring the oxygen saturation levels (SpO2) in blood as well as the heart rate (HR) of a patient. The photoplethysmographic signal (PPG ...
