  "description": "This ValueSet is part of the Health Device Data Transfer specification (HDDT) which defines profiles, operations, and value sets \\nfor sharing data between medical aids and digital health applications (DiGA). \\n\\nThis ValueSet defines the LOINC codes, used for relative lung function values. The relative value is calculated by dividing the \\nindividual measurement by the reference value, resulting in a percentage value (%). Included codes are for \\n- FEV1 measured/predicted\\n- PEF measured/personal best",
