  • Page 74: Pulse Oximetry

    Pulse oximeters use two different wavelengths of light (colors) and thus have the ability to determine one component of blood. The Model 2120 is calibrated to closely approximate functional oxygen saturation values. The Model 2120 oxygen saturation values will closely approximate co-oximeter fractional saturation values if the dysfunctional hemoglobin saturation levels are negligible.
