  "description" : "Dieses ValueSet 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\nDas ValueSet _HddtMivContinuousGlucoseMeasurement_ definiert den Mandatory Interoperable Value (MIV) \\\"Continuous Glucose Measurement\\\". Die Definition besteht aus\n- dieser Beschreibung, die die Semantik und die bestimmenden Merkmale des MIV liefert\n- einer Menge von LOINC-Codes, die MIV-konforme Messklassifikationen entlang der LOINC-Achsen _Komponente_, _System_, _Skala_ und _Methode_ definieren\n\nDer MIV _Continuous Glucose Measurement_ umfasst Werte aus der kontinuierlichen Überwachung des Glukosespiegels, z. B. \ndurch rtCGM im Interstitialfluid (ISF). Die Messungen werden mit Sensoren durchgeführt, die eine Abtastrate von bis zu \neinem Wert pro Minute (oder sogar mehr) ermöglichen. Dadurch kann der MIV _Continuous Glucose Measurement_ z. B. genutzt werden, um Zusammenhänge\nzwischen den individuellen Gewohnheiten und dem Glukosespiegel eines Patienten zu beurteilen. Aufgrund der hohen Dichte an Werten über einen langen\nZeitraum können aus _Continuous Glucose Measurement_ viele Schlüsselmetriken berechnet werden, die dem Patienten und seinem Arzt helfen,\nden Gesundheits- und Therapiezustand des Patienten einfach zu erfassen.\n\nDas ValueSet für den MIV _Continuous Glucose Measurement_ enthält Codes, die für die kontinuierliche Glukoseüberwachung (CGM) im Interstitialfluid (ISF) relevant sind, \nwobei Masse/Volumen und Mol/Volumen als gebräuchliche Einheiten berücksichtigt werden. In Zukunft können diesem ValueSet Codes für nicht-invasive Glukosemessmethoden hinzugefügt werden.\n\n--\n\nThis 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). Core of the HDDT specification are _Mandatory Interoperable \nValues_ (MIVs). MIVs are classes of measurements that contribute to defined use cases and purposes of DiGA.\n\nThis ValueSet defines the Mandatory Interoperable Value (MIV) \\\"Continuous Glucose Measurement\\\". The definition is made up from\n- this description which provides the semantics and defining characteristics of the MIV\n- a set of LOINC codes that define MIV-compliant measurement classifications along the LOINC axes _component_, _system_, _scale_ and _method_ \n\nThe MIV _Continuous Glucose Measurement_ covers values from continuous monitoring of the glucose level, e.g. \nby rtCGM in interstitial fluid (ISF). Measurements are performed through sensors with a sample rate of up to \none value per minute (or even more). By this, the MIV _Continuous Glucose Measurement_ can e.g. be used to assess dependencies between a \npatient's individual habits and behavious and his glucose level. Due to the high density of values over a long period \nof time, many key metrics can be calculated from _Continuous Glucose Measurement_ which help the patient and \nhis doctor to easily capture the status of the patient's health and therapy.\n\nThe ValueSet for the MIV _Continuous Glucose Measurement_ includes codes relevant to continuous glucose \nmonitoring (CGM) in interstitial fluid (ISF), considering mass/volume and moles/volume as commonly used units. \nIn the future codes defining non-invasive glucose measuring methods may be added to this value set.",
