A finger pulse oximeter is a small device which measures the amount of oxygen present in a patient’s blood. This is an indirect method of measuring blood oxygen levels, as opposed to a direct method such as testing a blood sample. The fingertip pulse oximeter device is worn on the tip of the finger, and uses light of particular wavelengths to measure oxygen saturation in the blood.
