Comparison of Green, Blue and Infrared Light in Wrist and Forehead Photoplethysmography

Vytautas Vizbara

Open publisher page 40 citations

Abstract

In this study we compared LED light sources of three different wavelengths: blue, green and infrared for the use in wrist and forehead photoplethysmography ( PPG ). Criteria for comparison were root mean square ( RMS ), pulsating to stationary tissue component ratio ( AC/DC ) and artifact to signal ratio ( ASR ). Our study showed that the green light is the most suitable for the wrist PPG and an infrared light source is better for the forehead PPG .
