## Union of http://hl7.org.au/fhir/core/StructureDefinition/au-core-bloodpressure and http://hl7.org.au/fhir/core/StructureDefinition/au-core-bloodpressure

This is the set of resources that conform to either of the profiles AU Core Blood Pressure (http://hl7.org.au/fhir/core/StructureDefinition/au-core-bloodpressure) and AU Core Blood Pressure (http://hl7.org.au/fhir/core/StructureDefinition/au-core-bloodpressure). E.g. what you have to deal with if you get resources conforming to one of them
