GLI-2012 Predicted Value according to Global Lung Initiative 2012 Reference value calculated based on the Global Lung Initiative 2012 equations. I.e the patient's 'race' is considered. GLI-2022 Predicted Value according to Global Lung Initiative 2022 Reference value calculated based on the Global Lung Initiative 2022 equations. I.e. a 'race'-neutral approach is used. other Other Other method used to determine the lung function reference value. Specify details via text input.

description:
  v: This CodeSystem 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). Core of the HDDT specification are _Mandatory Interoperable Values_ (MIVs). MIVs are classes of measurements that contribute to defined use cases and purposes of DiGA. The MIV _HddtMivLungFunctionTesting_ requires reference values for evaluating measured lung function values. These reference values can be determined using different methods. This CodeSystem provides codes to express typical methods for determining lung function reference values.
