description: Defines constraints on the Observation resource to represent inspired O2 by pulse oximetry and inspired oxygen concentration observations with a standard LOINC codes and UCUM units of measure. This profile is derived from the US Core Vital Signs Profile. package_name: hl7.fhir.us.core derivation: constraint name: USCorePulseOximetryProfile type: Observation elements: code: short: Oxygen Saturation by Pulse Oximetry mustSupport: true index: 0 elements: coding: mustSupport: true index: 1 slicing: rules: open discriminator: - {path: $this, type: pattern} min: null slices: PulseOx: match: {code: 59408-5, system: 'http://loinc.org'} schema: type: Coding mustSupport: true pattern: type: Coding value: {code: 59408-5, system: 'http://loinc.org'} _required: true index: 2 min: 1 max: 1 O2Sat: match: {code: 2708-6, system: 'http://loinc.org'} schema: type: Coding mustSupport: true pattern: type: Coding value: {code: 2708-6, system: 'http://loinc.org'} _required: true index: 3 min: 1 max: 1 component: short: Used when reporting flow rates or oxygen concentration. mustSupport: true index: 4 slicing: rules: open discriminator: - {path: code, type: pattern} min: null slices: FlowRate: match: code: coding: - {code: 3151-8, system: 'http://loinc.org'} schema: short: Inhaled oxygen flow rate mustSupport: true index: 5 elements: code: type: CodeableConcept mustSupport: true pattern: type: CodeableConcept value: coding: - {code: 3151-8, system: 'http://loinc.org'} index: 6 valueQuantity: mustSupport: true index: 7 elements: value: {mustSupport: true, index: 8} unit: {mustSupport: true, index: 9} system: type: uri pattern: {type: Uri, value: 'http://unitsofmeasure.org'} mustSupport: true index: 10 code: type: code pattern: {type: Code, value: L/min} mustSupport: true index: 11 required: [value, unit, system, code] Concentration: match: code: coding: - {code: 3150-0, system: 'http://loinc.org'} schema: short: Inhaled oxygen concentration mustSupport: true index: 12 elements: code: type: CodeableConcept mustSupport: true pattern: type: CodeableConcept value: coding: - {code: 3150-0, system: 'http://loinc.org'} index: 13 valueQuantity: mustSupport: true index: 14 elements: value: {mustSupport: true, index: 15} unit: {mustSupport: true, index: 16} system: type: uri pattern: {type: Uri, value: 'http://unitsofmeasure.org'} mustSupport: true index: 17 code: type: code pattern: {type: Code, value: '%'} mustSupport: true index: 18 required: [value, unit, system, code] package_version: 4.1.0 class: profile kind: resource url: http://hl7.org/fhir/us/core/StructureDefinition/us-core-pulse-oximetry base: http://hl7.org/fhir/us/core/StructureDefinition/us-core-vital-signs version: 4.1.0
