US Core Implementation Guide, published by HL7 International / Cross-Group Projects. This guide is not an authorized publication; it is the continuous build for version 10.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/US-Core/ and changes regularly. See the Directory of published versions

Resource Profile: US Core Pulse Oximetry Profile

Official URL: http://hl7.org/fhir/us/core/StructureDefinition/us-core-pulse-oximetry Version: 10.0.0-ballot
Standards status: Trial-use Maturity Level: 5 Computable Name: USCorePulseOximetryProfile
Other Identifiers: OID:2.16.840.1.113883.4.642.40.2.42.55

The US Core Pulse Oximetry Profile inherits from the US Core Vital Signs Profile. This profile sets minimum expectations for the Observation resource to record, search, and fetch pulse oximetry and inspired oxygen observations with standard LOINC codes and UCUM units of measure. It specifies which additional core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Example Usage Scenarios:

The following are example usage scenarios for this profile:

  • Query for pulse oximetry observations for a patient
  • Record or update pulse oximetry observations belonging to a patient

Mandatory and Must Support Data Elements

In addition to the Mandatory and Must Support data elements in the US Core Vital Signs Profile, the following data elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.

Each Observation Must Have:

  1. a fixed code for oxygen saturation in arterial blood as defined in the FHIR oxygen saturation profile
  2. an additional coding for oxygen saturation in arterial blood by pulse oximetry

Each Observation Must Support:

  1. a value for oxygen saturation1
  2. a code for inspired oxygen concentration2
  3. a value for inspired oxygen concentration

Profile Specific Implementation Guidance

This section provides detailed implementation guidance for the US Core Profile to support implementation and certification.

  • The observations MAY have additional codes that translate or map to the Observation code or category codes.§ For example:
    • providing a local system-specific code
    • providing more specific codes such as 8306-3 - Body height - lying in addition to 8302-2 - Body height. Several additional observation codes are provided in the FHIR core specification vital signs table.

    A code system value SHOULD be supplied for each additional code.§

  • The observations MAY have component observations.§ For example, to qualify the vital sign observation, 8310-5 - Body temperature, 8327-9 - Body temperature measurement site (oral, forehead, rectal, etc.) may be used as a component observation. The FHIR core specification vital signs table provides several of these.
  • 1An Observation without a value, SHALL include a reason why the data is absent unless there are 1) component observations, or 2) reporting panel observations using Observation.hasMember.§,§
    • For further guidance, see the Observation Grouping section in FHIR Specification.
    • Systems that never provide an observation without a value MAY choose not to support Observation.dataAbsentReason.§
  • 1An Observation.component without a value, SHALL include a reason why the data is absent.§
    • Systems that never provide a component observation without a component value MAY choose not to support Observation.component.dataAbsentReason.§
  • Implementers may use this profile as a base for other vital signs in addition to those in this guide.

  • Inspired oxygen therapy MAY be represented with component observations when measured at the same time as the pulse oximetry measurements.§ They are expressed as inhaled oxygen flow rate (e.g., 6 liters/min) and inhaled oxygen concentration (e.g., 40% oxygen).
    • This profile is technically non-conformant with the base FHIR version 4.0.1 vitals profile which defines a required binding that excludes the concept for L/min for Observation.component.value(x). This is a known issue and it means validation errors may occur when validating against this version of the US Core Pulse Oximetry Profile. A change request to correct this has been applied to the base FHIR ver 4.3.0 ("Release 4B").
  • Many pulse oximetry readings are taken while the patient is breathing room air. The concept of "room air" (unmodified, ambient air) SHOULD be represented as an inhaled oxygen flow rate of 0 liters/min.§
  • 2A pulse oximetry reading without inspired oxygen component observations may imply that the measurement was performed while the patient was breathing room air or that the inspired oxygen reading was omitted. To remove this uncertainty, the inspired oxygen component observations SHOULD be used.§

    This structure is derived from USCoreVitalSignsProfile

    Summary

    Mandatory: 2 elements(12 nested mandatory elements)
    Must-Support: 24 elements
    Fixed: 6 elements

    Slices

    This structure defines the following Slices:

    • The element 1 is sliced based on the value of Observation.code.coding
    • The element 1 is sliced based on the value of Observation.component

    Maturity: 5

     

    Other representations of profile: CSV, Excel, Schematron

    Notes:


    Quick Start


    Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile's information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

    • See the Scopes Format section for a description of the SMART scopes syntax.
    • See the Search Syntax section for a description of the US Core search syntax.
    • See the General Requirements section for additional rules and expectations when a Server requires status parameters.
    • See the General Guidance section for additional guidance on searching for multiple patients.

    US Core Scopes

    Servers providing access to vital signs data SHALL support these US Core SMART Scopes:

    • resource level scopes: <patient|user|system>/Observation.rs §

    • granular scopes: <patient|user|system>/Observation.rs?category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs §


    Mandatory Search Parameters:

    The following search parameters and search parameter combinations SHALL be supported:

    1. SHALL support searching for all Observations using the combination of the patient and category search parameters

      GET [base]/Observation?patient={Patient/}[id]&category={system|}[search_code]

      Example:

      1. GET [base]/Observation?patient=Patient/1137192&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs

      Implementation Notes: Fetches a bundle of all US Core Pulse Oximetry Profile resources for the specified patient and a category code = "vital-signs" ( see how to search by reference and how to search by token).

    2. SHALL support searching for all Observations by code using the combination of the patient and code search parameters

      • Including optional support OR search on code (e.g.code={system|}[code],{system|}[code],...)

      GET [base]/Observation?patient={Patient/}[id]&code={system|}[search_code]{,{system|}[code],...}

      Examples:

      1. GET [base]/Observation?patient=Patient/1137192&code=http://loinc.org|59408-5

      2. GET [base]/Observation?patient=Patient/1137192&code=http://loinc.org|59408-5,http://loinc.org|9279-1,http://loinc.org|8867-4

      Implementation Notes: Fetches a bundle of all US Core Pulse Oximetry Profile resources for the specified patient and observation code(s). SHOULD support search by multiple codes. The US Core Pulse Oximetry Profile "code" parameter searches only .code and not component.code. ( see how to search by reference and how to search by token).

    3. SHALL support searching for all Observations by date (for example, results after 2018) using the combination of the patient and category and date search parameters

      • Including optional support for AND search on date (e.g.date=[date]&date=[date]&...)

      • Including support for these date comparators: "gt", "lt", "ge", "le"

      GET [base]/Observation?patient={Patient/}[id]&category={system|}[search_code]&date={gt|lt|ge|le}[dateTime]{&date={gt|lt|ge|le}[dateTime]&...}

      Example:

      1. GET [base]/Observation?patient=Patient/1137192&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&date=ge2018-03-14T00:00:00Z

      Implementation Notes: Fetches a bundle of all US Core Pulse Oximetry Profile resources for the specified patient and date and a category code = "vital-signs" ( see how to search by reference and how to search by token and how to search by date).

    Optional Search Parameters:

    The following search parameters and search parameter combinations SHOULD be supported

    1. SHOULD support searching for all Observations for a patient for a given status (for example all observations marked as final) using the combination of the patient and category and status search parameters

      • Including support OR search on status (e.g.status={system|}[code],{system|}[code],...)

      GET [base]/Observation?patient={Patient/}[id]&category={system|}[search_code]&status={system|}[search_code]{,{system|}[code],...}

      Example:

      1. GET [base]/Observation?patient=Patient/1137192&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&status=final

      Implementation Notes: Fetches a bundle of all US Core Pulse Oximetry Profile resources for the specified patient and category = "vital-signs" and status ( see how to search by reference and how to search by token).

    2. SHOULD support searching using the combination of the patient and category and _lastUpdated search parameters

      • Including optional support for AND search on _lastUpdated (e.g._lastUpdated=[date]&_lastUpdated=[date]&...)

      • Including support for these _lastUpdated comparators: "gt", "lt", "ge", "le"

      GET [base]/Observation?patient={Patient/}[id]&category={system|}[search_code]&_lastUpdated=[dateTime]

      Example:

      1. GET [base]/Observation?patient=Patient/1137192&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&_lastUpdated=ge2024-01-01T00:00:00Z

      Implementation Notes: Fetches a bundle of all US Core Pulse Oximetry Profile resources for the specified patient and category code = "vital-signs" and _lastUpdated. See the US Core General Guidance page for Searching Using lastUpdated. ( see how to search by reference and how to search by token and how to search by date).

    3. SHOULD support searching Observations by code and date using the combination of the patient and code and date search parameters

      • Including optional support OR search on code (e.g.code={system|}[code],{system|}[code],...)

      • Including optional support for AND search on date (e.g.date=[date]&date=[date]&...)

      • Including support for these date comparators: "gt", "lt", "ge", "le"

      GET [base]/Observation?patient={Patient/}[id]&code={system|}[search_code]{,{system|}[code],...}&date={gt|lt|ge|le}[dateTime]{&date={gt|lt|ge|le}[dateTime]&...}

      Example:

      1. GET [base]/Observation?patient=Patient/1137192&code=http://loinc.org|59408-5&date=ge2019-01-01T00:00:00Z

      Implementation Notes: Fetches a bundle of all US Core Pulse Oximetry Profile resources for the specified patient and date and code(s). SHOULD support search by multiple codes. ( see how to search by reference and how to search by token and how to search by date).
