Detailed Descriptions for the elements in the DeviceMetric resource.

DeviceMetric
Element IdDeviceMetric
Definition

Describes a measurement, calculation or setting capability of a medical device.

Cardinality0..*
TypeDomainResource
Summarytrue
Comments

For the initial scope, this DeviceMetric resource is only applicable to describe a single metric node in the containment tree that is produced by the context scanner in any medical device that implements or derives from the ISO/IEEE 11073 standard.

DeviceMetric.identifier
Element IdDeviceMetric.identifier
Definition

Unique instance identifiers assigned to a device by the device or gateway software, manufacturers, other organizations or owners. For example: handle ID.

NoteThis is a business identifier, not a resource identifier (see discussion)
Cardinality0..*
TypeIdentifier
Summarytrue
Comments

For identifiers assigned to a device by the device or gateway software, the system element of the identifier should be set to the unique identifier of the device.

DeviceMetric.type
Element IdDeviceMetric.type
Definition

Describes the type of the metric. For example: Heart Rate, PEEP Setting, etc.

Cardinality1..1
Terminology BindingDevice Metric and Component Types (Preferred)
TypeCodeableConcept
Summarytrue
Comments

DeviceMetric.type can be referred to either IEEE 11073-10101 or LOINC.

DeviceMetric.unit
Element IdDeviceMetric.unit
Definition

Describes the unit that an observed value determined for this metric will have. For example: Percent, Seconds, etc.

Cardinality0..1
Terminology BindingDevice Metric and Component Types (Preferred)
TypeCodeableConcept
Summarytrue
Comments

DeviceMetric.unit can refer to either UCUM or preferable a RTMMS coding system.

DeviceMetric.source
Element IdDeviceMetric.source
Definition

Describes the link to the Device that this DeviceMetric belongs to and that contains administrative device information such as manufacturer, serial number, etc.

Cardinality0..1
TypeReference(Device)
Summarytrue
DeviceMetric.parent
Element IdDeviceMetric.parent
Definition

Describes the link to the Device that this DeviceMetric belongs to and that provide information about the location of this DeviceMetric in the containment structure of the parent Device. An example would be a Device that represents a Channel. This reference can be used by a client application to distinguish DeviceMetrics that have the same type, but should be interpreted based on their containment location.

Cardinality0..1
TypeReference(Device)
Summarytrue
DeviceMetric.operationalStatus
Element IdDeviceMetric.operationalStatus
Definition

Indicates current operational state of the device. For example: On, Off, Standby, etc.

Cardinality0..1
Terminology BindingDeviceMetricOperationalStatus (Required)
Typecode
Summarytrue
DeviceMetric.color
Element IdDeviceMetric.color
Definition

Describes the color representation for the metric. This is often used to aid clinicians to track and identify parameter types by color. In practice, consider a Patient Monitor that has ECG/HR and Pleth for example; the parameters are displayed in different characteristic colors, such as HR-blue, BP-green, and PR and SpO2- magenta.

Cardinality0..1
Terminology BindingDeviceMetricColor (Required)
Typecode
Summarytrue
DeviceMetric.category
Element IdDeviceMetric.category
Definition

Indicates the category of the observation generation process. A DeviceMetric can be for example a setting, measurement, or calculation.

Cardinality1..1
Terminology BindingDeviceMetricCategory (Required)
Typecode
Summarytrue
DeviceMetric.measurementPeriod
Element IdDeviceMetric.measurementPeriod
Definition

Describes the measurement repetition time. This is not necessarily the same as the update period. The measurement repetition time can range from milliseconds up to hours. An example for a measurement repetition time in the range of milliseconds is the sampling rate of an ECG. An example for a measurement repetition time in the range of hours is a NIBP that is triggered automatically every hour. The update period may be different than the measurement repetition time, if the device does not update the published observed value with the same frequency as it was measured.

Cardinality0..1
TypeTiming
Summarytrue
DeviceMetric.calibration
Element IdDeviceMetric.calibration
Definition

Describes the calibrations that have been performed or that are required to be performed.

Cardinality0..*
Summarytrue
DeviceMetric.calibration.type
Element IdDeviceMetric.calibration.type
Definition

Describes the type of the calibration method.

Cardinality0..1
Terminology BindingDeviceMetricCalibrationType (Required)
Typecode
Summarytrue
DeviceMetric.calibration.state
Element IdDeviceMetric.calibration.state
Definition

Describes the state of the calibration.

Cardinality0..1
Terminology BindingDeviceMetricCalibrationState (Required)
Typecode
Summarytrue
DeviceMetric.calibration.time
Element IdDeviceMetric.calibration.time
Definition

Describes the time last calibration has been performed.
