A portable pulse oximeter is an instrument that measures blood oxygen saturation.  What differentiates this from traditional blood oxygen monitors is that it is done non-invasively. Typically such an instrument has a pair of small LEDs at 660 nm and Infrared (IR) wavelengths facing photodiodes through a translucent part of the patient's body, usually a fingertip.
