FHIR Blood Pressure Profile

This profile was published on Sat, Aug 11, 2018 00:00+0000 as a draft by HL7 International / Orders and Observations.

Description of Profiles, Differentials, Snapshots, and how the XML and JSON presentations work.

This structure is derived from Observationvitalsignsbase.

Summary

  1. One code in Observation.category which must have
    • a fixed Observation.category.coding.system='http ://loinc.org'
    • a fixed Observation.code.coding.code= 85354-9'
    • The code (or codes) for the measurement obtained in Observation.code. All codes SHALL have a system value
  2. One Observation.component.code which must have
    • a fixed Observation.component.code.coding.system='http://loinc.org'
    • fixed Observation.component.code.coding.code= '8480-6'
    • The code (or codes) for the measurement obtained in Observation.code. All codes SHALL have a system value
  3. One Observation.component.code which must have
    • a fixed Observation.component.code.coding.system='http://loinc.org'
    • fixed Observation.component.code.coding.code= '8462-4'
    • The code (or codes) for the measurement obtained in Observation.code. All codes SHALL have a system value
  4. Either one Observation.valueQuantity or, if there is no value, one code in Observation.DataAbsentReason
    • Each Observation.valueQuantity must have:
      • One numeric value in Observation.valueQuantity.value
      • a fixed Observation.valueQuantity.system="http://unitsofmeasure.org"
      • a UCUM unit code in Observation.valueQuantity.code = 'mm[Hg]'

Mandatory: 9 elements (+8 nested mandatory elements)
Must-Support: 8 elements
Fixed Value: 4 elements
Prohibited: 1 element

Extensions

This structure refers to these extensions:

Slices

This structure defines the following Slices:

  • The element Observation.category is sliced based on the value of pattern:$this
  • The element Observation.component is sliced based on the values of value:code.coding.code, value:code.coding.system

This indicates the differences between this profile and the base Observationvitalsignsbase structure.
