  "description" : "Dieses CodeSystem ist Teil der Health Device Data Transfer Spezifikation (HDDT), die Profile, Operationen und ValueSets für den Datenaustausch zwischen \nHilfsmitteln und digitalen Gesundheitsanwendungen (DiGA) definiert. Zentrales Element der HDDT-Spezifikation sind _Mandatory Interoperable Values_ (MIVs).\nMIVs sind Klassen von Messwerten, die zu definierten Anwendungsfällen und Zwecken von DiGA beitragen.\n\nDer MIV _HddtMivLungFunctionTesting_ erfordert Referenzwerte zur Bewertung gemessener Lungenfunktionswerte. Diese Referenzwerte können mit unterschiedlichen\nMethoden bestimmt werden. Dieses CodeSystem stellt Codes zur Verfügung, um typische Methoden zur Bestimmung von Lungenfunktions-Referenzwerten auszudrücken.\n\n--\n\nThis CodeSystem 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).
