Resource Profile: Oxygen Saturation in Arterial Blood by Pulse Oximetry

Official URL: http://hl7.org/fhir/us/vitals/StructureDefinition/oxygen-saturation-arterial-blood-pulseOx Version: 2.0.0
Draft as of 2024-10-09 Computable Name: OxygenSaturationArterialBloodPulseOx

Copyright/Legal: Logica Health, all rights reserved Creative Commons License

A measurement of the percentage to which oxygen is bound to hemoglobin in arterial blood via pulse oximetry.

Scope

The Oxygen saturation in Arterial blood via Pulse oximetry profile contains one observation for the relative amount of oxygen in arterial blood as measured by a pulse oximeter,, given in percent. In addition, the profile contains the following qualifying observations with associated SNOMED CT value sets: Sensordescription, MeasurementSetting, and ExerciseAssociation.

Examples

The following examples are provided to illustrate conformant resource content to this profile.

Use Cases

1. Oxygen saturation measured with pulse oximeter probe.

Value sets

Value Set Purpose
Sensor Description value set This reference set contains the instrument used when an oxygen saturation is measured in arterial blood by pulse oximetry, referencing the LOINC term "Oxygen Saturation Sensor Type" 73803-9
Oxygen Saturation Body Location value set This reference set contains a constrained list body location values used to record the site where an oximeter was placed, and capillary oxygen saturation measured.
Exertion Phase value set This value set is used to result the Exercise Association extension.
