A Pulse Oximeter is a medical device that indirectly monitors the oxygen saturation of a patient’s blood and changes in blood
volume in the skin, producing a photoplethysmogram.
Pulse Oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. It provides continuous, noninvasive onitoring of oxygen saturation of hemoglobin
in arterial blood.
