Detailed Descriptions for the elements in the DeviceMetric resource.

DeviceMetric
Element Id DeviceMetric
Definition

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

Short Display Measurement, calculation or setting capability of a medical device
Cardinality 0..*
Type DomainResource
Summary false
Comments

The DeviceMetric resource is derived from the ISO/IEEE 11073-10201 Domain Information Model standard, but is more widely applicable.

DeviceMetric.identifier
Element Id DeviceMetric.identifier
Definition

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

Short Display Instance identifier
Note This is a business identifier, not a resource identifier (see discussion)
Cardinality 0..*
Type Identifier
Summary true
Comments

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

DeviceMetric.type
Element Id DeviceMetric.type
Definition

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

Short Display Identity of metric, for example Heart Rate or PEEP Setting
Cardinality 1..1
Terminology Binding Device Metric and Component Types (Preferred)
Type CodeableConcept
Summary true
Comments

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

DeviceMetric.unit
Element Id DeviceMetric.unit
Definition

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

Short Display Unit of Measure for the Metric
Cardinality 0..1
Terminology Binding UCUM Codes (Preferred)
Type CodeableConcept
Summary true
Comments

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

DeviceMetric.device
Element Id DeviceMetric.device
Definition

Describes the link to the Device. This is also known as a channel device.

Short Display Describes the link to the Device
Cardinality 1..1
Type Reference(Device)
Summary true
Comments

Note if this is not the top level device - also know as the source device, it may be referenced in the device.parent element.

DeviceMetric.operationalStatus
Element Id DeviceMetric.operationalStatus
Definition

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

Short Display on | off | standby | entered-in-error
Cardinality 0..1
Terminology Binding Device Metric Operational Status (Required)
Type code
Summary true
DeviceMetric.color
Element Id DeviceMetric.color
Definition

The preferred color associated with the metric (e.g., display color). 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; the metrics are displayed in different characteristic colors, such as HR in blue, BP in green, and PR and SpO2 in magenta.

Short Display Color name (from CSS4) or #RRGGBB code
Cardinality 0..1
Terminology Binding Color Codes (Names or RGB Values) (Required)
Type code
Summary false
DeviceMetric.category
Element Id DeviceMetric.category
Definition

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

Short Display The kind of metric represented
Cardinality 1..1
Terminology Binding Device Metric Category (Extensible)
Type CodeableConcept
Summary true
DeviceMetric.measurementFrequency
Element Id DeviceMetric.measurementFrequency
Definition

The frequency at which the metric is taken or recorded. Devices measure metrics at a wide range of frequencies; for example, an ECG might sample measurements in the millisecond range, while an NIBP might trigger only once an hour. Less often, the measurementFrequency may be based on a unit other than time, such as distance (e.g. for a measuring wheel). The update period may be different than the measurement frequency, if the device does not update the published observed value with the same frequency as it was measured.

Short Display Indicates how often the metric is taken or recorded
Cardinality 0..1
Type Quantity
Summary false
DeviceMetric.calibration
Element Id DeviceMetric.calibration
Definition

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

Short Display Describes the calibrations that have been performed or that are required to be performed
Cardinality 0..*
Summary false
DeviceMetric.calibration.type
Element Id DeviceMetric.calibration.type
Definition

Describes the type of the calibration method.

Short Display The method of calibration
Cardinality 0..1
Terminology Binding Device Metric Calibration Type (Extensible)
Type CodeableConcept
Summary false
DeviceMetric.calibration.state
Element Id DeviceMetric.calibration.state
Definition

Describes the state of the calibration.

Short Display not-calibrated | calibration-required | calibrated | unspecified
Cardinality 0..1
Terminology Binding Device Metric Calibration State (Required)
Type code
Summary false
DeviceMetric.calibration.time
Element Id DeviceMetric.calibration.time
Definition

Describes the time last calibration has been performed.

Short Display Describes the time last calibration has been performed
Cardinality 0..1
Type instant
Summary false
