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 |
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 |
