Given the Test Description: "The system under test MUST return the complete resource in response to an HTTP GET request to its URL (READ)."

Given the Preconditions: - The test data set must have been recorded in the system under test according to the specifications (manually).

• The ID of the corresponding FHIR resource for this test data set must be stored in the configuration variable 'observation-read-arterial-oxygen-saturation-id'.

Create an Observation resource in your system with the following values:

• Id: the value of the configuration variable 'observation-read-arterial-oxygen-saturation-id'
• Profile: ISiKSauerstoffsaettigungArteriell
• Status: final
• Category: vital-signs
• Code:
  • Coding:
    • Code: 2708-6
    • Display: Oxygen saturation in Arterial blood by Pulse oximetry
    • System: http://loinc.org
    • Version: 2.81 (can be configured with the property 'loinc-version')
• Patient: any (the linked Patient resource must conform to ISiKPatient; store the ID in 'observation-patient-id')
• Encounter: any (the linked Encounter resource must conform to ISiKKontaktGesundheitseinrichtung; store the ID in 'observation-encounter-id')
• Performer: any (the linked Practitioner resource must conform to ISiKPersonImGesundheitsberuf; store the ID in 'observation-practitioner-id')
• Effective date/time: 2026-03-05
• Value: 98 %
• (Optional) Device: any (store the ID in 'observation-read-device-id')
• (Optional) Method:
  • Coding:
    • Code: 252465000
    • Display: Pulsoximetrie
    • System: http://snomed.info/sct
    • Version: can be configured with the property 'snomed-ct-version'

Then Get FHIR resource at "http://fhirserver/metadata" with content type "json"
