7.2 Functional Versus Fractional
Saturation
This oximeter measures functional
saturation-oxygenated hemoglobin expressed as a
percentage of the hemoglobin that can transport oxygen.
It does not detect significant amounts of dysfunctional
hemoglobin, such as carboxyhemoglobin or
methemoglobin.
In contrast, hemoximeter such as the IL482 report
fractional saturation-oxygenated hemoglobin expressed
as a percentage of all measured hemoglobin, including
measured dysfunctional hemoglobins.
