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 relative Lungenfunktionswerte verwendet werden. Der relative Wert wird berechnet, indem die individuelle Messung durch den Referenzwert geteilt wird, was zu einem Prozentwert (%) führt. Enthaltene Codes sind für

  • FEV1 measured/predicted
  • PEF measured/predicted

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 relative lung function values. The relative value is calculated by dividing the individual measurement by the reference value, resulting in a percentage value (%). Included codes are for

  • FEV1 measured/predicted
  • PEF measured/predicted

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
