## Operational Theory
Pulse oximetry is based on the [Beer-Lambert law](, a principle that relates the concentration of a species to the attenuation of light through a sample:
where $`I`$ is the intensity of light transmitted through the sample; $`I_in`$ is the intensity of the light prior to absorption by the sample; $`D`$ is the optical path length; $`C`$ is the solute concentration; and $`\epsilon`$ is the extinction coefficient, the sample's absorption at a given wavelength of light.
