Observations are often coded in multiple code systems.
- LOINC provides a very specific code (though not more specific in this particular
case)
- snomed provides a clinically relevant code that is usually less granular
than LOINC
- the source system provides its own code, which may be less or more granular
than LOINC
this is shown here to demonstrate the concept of translations within the codeableConcept
datatype. The diastolic code below only has a LOINC code
