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.
