  <description
               value="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."/>
