To obtain FDA labeling for "medical use," the manufacturers should submit their devices to rigorous testing on human volunteers. Accurate pulse oximeters utilize correction components based mostly on the in vivo comparison of arterial hemoglobin oxygen saturation obtained from direct measurement of arterial blood gases with what the pulse oximeter obtains over a wide range of oxygen saturations. These correction factors assist account for causes of known variability, including anemia, mild scattering, venous and tissue pulsation by mechanical power from close by arteries, pulsatile variations in tissue thickness in the light path aside from in the arteries, nail polish, and pores and skin pigmentation.
