LOINC Code 89277-8: SaO2% during anesthesia Pulse oximetry (BldA) [Mass fraction]

89277-8 is a LOINC code used to identify SaO2% during anesthesia Pulse oximetry (BldA) [Mass fraction] 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 saturation^during anesthesia. It is commonly used with the system or sample type BldA.
