Dieses ValueSet ist Teil der Health Device Data Transfer Spezifikation (HDDT), die Profile, Operationen und ValueSets für den Datenaustausch zwischen Hilfsmitteln und digitalen Gesundheitsanwendungen (DiGA) definiert.

Dieses ValueSet definiert die LOINC-Codes, die für Referenzwerte der Lungenfunktion verwendet werden:

  • Der Referenzwert für den Peak Expiratory Flow (PEF) ist der persönliche Bestwert, den der Patient innerhalb eines bestimmten Zeitraums erreicht hat.
  • 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.

This ValueSet is part of the Health Device Data Transfer specification (HDDT) which defines profiles, operations, and value sets for sharing data between medical aids and digital health applications (DiGA).

This ValueSet defines the LOINC codes, used for lung function reference values:

  • The reference value for Peak Expiratory Flow (PEF) is the personal best value achieved by the patient within a certain time frame.
  • 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.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
