Term Description

Because of the confusion that occurs in countries that report results as both decimal fraction and percent, this property was created to represent decimal fractions that are reported without units.

Part Description

LP21258-6   Oxygen saturation
Oxygen saturation (sO2) is defined as the ratio of oxyhemoglobin to "active" hemoglobin (oxyhemoglobin + deoxyhemoglobin). Some say the term oxygen saturation has been erroneously redefined with a denominator of "total" instead of "active" hemoglobin, an ambiguity that can sometimes create confusion when viewing reported values from different instruments (Anesth Analg. 2007 Dec;105(6 Suppl):S5-9.) Oxygen saturation is commonly measured by blood gas analyzers and pulse oximetry. Source: Regenstrief LOINC
