Detailed Descriptions for the elements in the DeviceMetric resource.

DeviceMetric
Element IdDeviceMetric
Definition

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

Short DisplayMeasurement, calculation or setting capability of a medical device
Cardinality0..*
TypeDomainResource
Summaryfalse
Comments

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

DeviceMetric.identifier
Element IdDeviceMetric.identifier
Definition

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

Short DisplayInstance identifier
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 any identifier of the device.

DeviceMetric.type
Element IdDeviceMetric.type
Definition

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

Short DisplayIdentity of metric, for example Heart Rate or PEEP Setting
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.

Short DisplayUnit of Measure for the Metric
Cardinality0..1
Terminology BindingUCUM Codes (Preferred)
TypeCodeableConcept
Summarytrue
Comments

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

DeviceMetric.device
Element IdDeviceMetric.device
Definition

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

Short DisplayDescribes the link to the Device
Cardinality1..1
TypeReference(Device)
Summarytrue
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 IdDeviceMetric.operationalStatus
Definition

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

Short Displayon | off | standby | entered-in-error
Cardinality0..1
Terminology BindingDevice Metric Operational Status (Required)
Typecode
Summarytrue
DeviceMetric.color
Element IdDeviceMetric.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 DisplayColor name (from CSS4) or #RRGGBB code
Cardinality0..1
Terminology BindingColor Codes (Names or RGB Values) (Required)
Typecode
Summaryfalse
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.

Short Displaymeasurement | setting | calculation | unspecified
Cardinality1..1
Terminology BindingDevice Metric Category (Required)
Typecode
Summarytrue
DeviceMetric.measurementFrequency
Element IdDeviceMetric.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 DisplayIndicates how often the metric is taken or recorded
Cardinality0..1
TypeQuantity
Summaryfalse
DeviceMetric.calibration
Element IdDeviceMetric.calibration
Definition

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

Short DisplayDescribes the calibrations that have been performed or that are required to be performed
Cardinality0..*
Summaryfalse
DeviceMetric.calibration.type
Element IdDeviceMetric.calibration.type
Definition

Describes the type of the calibration method.

Short Displayunspecified | offset | gain | two-point
Cardinality0..1
Terminology BindingDevice Metric Calibration Type (Required)
Typecode
Summaryfalse
DeviceMetric.calibration.state
Element IdDeviceMetric.calibration.state
Definition

Describes the state of the calibration.

Short Displaynot-calibrated | calibration-required | calibrated | unspecified
Cardinality0..1
Terminology BindingDevice Metric Calibration State (Required)
Typecode
Summaryfalse
DeviceMetric.calibration.time
Element IdDeviceMetric.calibration.time
Definition

Describes the time last calibration has been performed.

Short DisplayDescribes the time last calibration has been performed
Cardinality0..1
Typeinstant
