## Resource Profile: Sample Array Observation profile 

| | | |
| :--- | :--- | :--- |
| *Official URL*:http://hl7.org/fhir/uv/pocd/StructureDefinition/SampleArrayObservation | *Version*:1.0.0 | |
| * Standards status: *[Trial-use](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 2 | *Computable Name*:SampleArrayObservation |

 
StructureDefinition for Observation resources that represent real-time waveforms or wave snippets. 

## Scope and Usage

This profile sets minimum expectations for the [Observation](http://hl7.org/fhir/R4/observation.html) resource that represents real-time waveform or wave snippet.

**Usages:**

* Examples for this Profile: [Observation/CVPSampleArrayObservation](Observation-CVPSampleArrayObservation.md) and [Observation/ECGSampleArrayObservation](Observation-ECGSampleArrayObservation.md)
* CapabilityStatements using this Profile: [Server capability requirements](CapabilityStatement-ServerCapabilityStatement.md)
