description: To promote interoperability and adoption through common implementation, this profile sets minimum expectations for the Observation resource to record, search, and fetch pulse oximetry and inspired oxygen observations with a standard LOINC codes and UCUM units of measure. It is based on the US Core Vital Signs Profile and identifies which *additional* core elements, extensions, vocabularies, and value sets **SHALL** be present and constrains the way the elements are used when using the profile. It provides the floor for standards development for specific use cases.
