Detailed Descriptions for the elements in the DeviceMetric resource.

Comments DeviceMetric.type can be referred to either GDMN (nomenclature system supported by FDA Global UDI Database) or preferable RTMMS coding system.
DeviceMetric
Definition

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

Control 1..1
Summary true
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.type DeviceMetric.identifier
Definition

Describes the type unique identification of this metric that has been assigned by the metric. device or gateway software. For example: Heart Rate, PEEP Setting, etc. handle ID. It should be noted that in order to make the identifier unique, the system element of the identifier should be set to the unique identifier of the device.

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

DeviceMetric.unit
Definition

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

DeviceMetric.source
Definition

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

Control 0..1
Type Reference ( Device )
Summary true
DeviceMetric.parent
Definition

Describes the link to the DeviceComponent 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 DeviceComponent 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.

Control 0..1
Type Reference ( DeviceComponent )
Summary true
DeviceMetric.operationalStatus
Definition

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

Control 0..1
Terminology Binding DeviceMetricOperationalStatus: Describes the operational status of the DeviceMetric. DeviceMetricOperationalStatus ( Required )
Type code
Summary true
DeviceMetric.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.

Control 0..1
Terminology Binding DeviceMetricColor: Describes the typical color of representation. DeviceMetricColor ( Required )

Summary true
DeviceMetric.category
Definition

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

Control 1..1
Terminology Binding DeviceMetricCategory: Describes the category of the metric. DeviceMetricCategory ( Required )
Type code
Summary true
DeviceMetric.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.

Control 0..1

Summary true
DeviceMetric.calibration
Definition

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

Control 0..*
