  <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). 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.

This ValueSet defines the Mandatory Interoperable Value (MIV) \&quot;Continuous Glucose Measurement\&quot;. The definition is made up from
- this description which provides the semantics and defining characteristics of the MIV
- a set of LOINC codes that define MIV-compliant measurement classifications along the LOINC axes _component_, _system_, _scale_ and _method_ 

The MIV _Continuous Glucose Measurement_ covers values from continuous monitoring of the glucose level, e.g. 
by rtCGM in interstitial fluid (ISF). Measurements are performed through sensors with a sample rate of up to 
one value per minute (or even more). By this, the MIV _Continuous Glucose Measurement_ can e.g. be used to assess dependencies between a 
patient's individual habits and behavious and his glucose level. Due to the high density of values over a long period 
of time, many key metrics can be calculated from _Continuous Glucose Measurement_ which help the patient and 
his doctor to easily capture the status of the patient's health and therapy.

The ValueSet for the MIV _Continuous Glucose Measurement_ includes codes relevant to continuous glucose 
monitoring (CGM) in interstitial fluid (ISF), considering mass/volume and moles/volume as commonly used units. 
In the future codes defining non-invasive glucose measuring methods may be added to this value set."/>
