How Does a Pulse Oximeter Work?

Pulse oximeters, whether a finger oximeter or bedside monitor, shine light through the skin to measure and detect changes in the amount of light absorption by the blood. The process is completely non-invasive, and the data is used to calculate the level of oxygen present in the blood as well as heart rate and other vitals. At AED.US, we offer high-quality Masimo pulse oximeters, including the MightSat Rx finger oximeter and Masimo RAD-97 bedside monitors.
