LOINC Code 10240-0: Oxygen content (RV) [Moles/Vol]

10240-0 is a LOINC code used to identify Oxygen content (RV) [Moles/Vol] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Oxygen content.
