## Resource Profile: Channel Device profile 

| | | |
| :--- | :--- | :--- |
| *Official URL*:http://hl7.org/fhir/uv/pocd/StructureDefinition/ChannelDevice | *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*:ChannelDevice |

 
StructureDefinition for Device resources that represent Channels, which are used for grouping metrics together. 

## Scope and Usage

This profile sets minimum expectations for the [Device](http://hl7.org/fhir/R4/device.html) resource that represents a Channel, which is used for grouping metrics together.

**Usages:**

* Refer to this Profile: [Enumeration DeviceMetric profile](StructureDefinition-EnumerationDeviceMetric.md), [Numeric DeviceMetric profile](StructureDefinition-NumericDeviceMetric.md) and [Sample Array DeviceMetric profile](StructureDefinition-SampleArrayDeviceMetric.md)
* Examples for this Profile: [Device/BloodPressureChannelDevice](Device-BloodPressureChannelDevice.md), [Device/ECGChannelDevice](Device-ECGChannelDevice.md), [Device/HeartRateChannelDevice](Device-HeartRateChannelDevice.md) and [Device/NBPChannelDevice](Device-NBPChannelDevice.md)
* CapabilityStatements using this Profile: [Server capability requirements](CapabilityStatement-ServerCapabilityStatement.md)
