           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
