OXIMETER APPARATUS AND METHOD FOR MEASURING ARTERIAL BLOOD CONSTITUENTS ABSTRACT An oximeter and method is disclosed for non- invasively measuring blood which is capable of determining the oxygen saturation of arterial blood. The oximeter includes at least one light source addressed to a tissue area of a patient, such as a finger or earlobe. A photo-detector receives emitted light passing through the sample and a receiver circuit analyzes the data and produces an output which is proportional to the oxygen content of blood. The light source is driven at a preselected carrier frequency and the receiver circuit is tuned to said carrier frequency so that undesired signals can be filtered out leaving only the signals created by the emitted light passing through said tissue. The oxygen content is calculated using the patient's known red cell count, thereby correcting the final saturation value for patient anemia, Moreover, the calculation for oxygen saturation incorporates red cell scattering parameters for increased accuracy in clinical environments.
