3 Introduction
3.1 Working Principle
The Pulse Oximeter works by applying a sensor to a pulsating
arteriolar vascular bed. The sensor contains a dual light source
and photo detector. Skin,bone, tissue, and veins normally absorb
a constant amount of light during systole and diastole, as blood
volume increases and decreases. The ratio of light absorbed at
systole and diastole is translated into an oxygen saturation
measurement. This measurement is referred to as SpO2.
