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

Associated Observations

89263-8 Special circumstances associated observations panel

This panel contains all of the "Special circumstances" LOINC codes that are used to report the specific context during which a particular measurement was taken, where that context may affect the measurement value. Circumstances that can affect measurement of certain variables include when the patient is asleep, in pain, crying, febrile, or during a period of apnea. This panel is attached to the generic LOINC code for each measurement so that the circumstance under which the measurement was taken can be reported along with the primary result.
