Abstract:Heart rate and blood oxygen saturation level are essential medical parameters that can be measured optically by photoplethysmography. However, certain individuals present variability in skin absorption that can affect the proper quantification of both pulse and blood oxygen level. In this work, we designed an optical device capable of measuring these variables, trying to improve the accuracy by means of different electronic signal processing. A final accuracy of 0.5 beats per minute and 0.5% was determined for… Show more
