  <description value="Dieses ValueSet ist Teil der Health Device Data Transfer Spezifikation (HDDT), die Profile, Operationen und ValueSets für den Datenaustausch zwischen &#xA;Hilfsmitteln und digitalen Gesundheitsanwendungen (DiGA) definiert.&#xA;&#xA;Dieses ValueSet definiert die LOINC-Codes, die für Referenzwerte der Lungenfunktion verwendet werden:&#xA;- Der Referenzwert für den _Peak Expiratory Flow_ (PEF) ist der persönliche Bestwert, den der Patient innerhalb eines bestimmten Zeitraums erreicht hat.&#xA;- Der Referenzwert für das Forcierte Exspiratorische Volumen in 1 Sekunde (FEV1) ist in den meisten Fällen ein vorhergesagter Wert, der auf Basis der demografischen Daten des Patienten berechnet wird.&#xA;&#xA;--&#xA;&#xA;This ValueSet is part of the Health Device Data Transfer specification (HDDT) which defines profiles, operations, and value sets &#xA;for sharing data between medical aids and digital health applications (DiGA). &#xA;&#xA;This ValueSet defines the LOINC codes, used for lung function reference values:&#xA;- The reference value for Peak Expiratory Flow (PEF) is the personal best value achieved by the patient within a certain time frame. &#xA;- The reference value for Forced Expiratory Volume in 1 second (FEV1) is in most cases a predicted value, calculated based on demographic data of the patient."/>
