The underlying science of pulse oximetry is based on a simple manipulation of the Lambert–
Beer law, which describes the attenuation of light traveling through a mixture of absorbers …

BACKGROUND: Universal access to pulse oximetry worldwide is often limited by cost and
has substantial public health consequences. Low-cost pulse oximeters have become …
