Summary

Complex Extension: StructureDefinition that adds a typed reference range (low, high, and range type) to a DeviceMetric. This extension is included in the PoCD IG but is intended to move to the FHIR Extensions Pack.

  • low: Quantity: The lower bound of the reference range.
  • high: Quantity: The upper bound of the reference range.
  • type: CodeableConcept: Classifies the reference range as alarm limits, physiological range, or technical range.
