Definitions for the StructureDefinition-SensorDescriptionExt Profile.
1. Extension | |
Definition | The kind of sensor used to measure the oxygen saturation. |
Control | 0..1 This element is affected by the following invariants: ele-1 |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
2. Extension.id | |
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
Control | 0..1 |
Type | string |
3. Extension.extension | |
Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
Control | 0..* |
Type | Extension |
Alternate Names | extensions, user content |
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
Slicing | This element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
4. Extension.url | |
Definition | Source of the definition for the extension code - a logical name or a URL. |
Control | 1..1 |
Type | uri |
Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |
Fixed Value | http://hl7.org/fhir/us/vitals/StructureDefinition/SensorDescriptionExt |
5. Extension.value[x] | |
Definition | Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |
Control | 0..1 |
Type | CodeableConcept |
[x] Note | See Choice of Data Types for further information about how to use [x] |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
Slicing | This element introduces a set of slices on Extension.value[x]. The slices are unordered and Closed, and can be differentiated using the following discriminators:
|
6. Extension.value[x]:valueCodeableConcept | |
SliceName | valueCodeableConcept |
Definition | A concept that may be defined by a formal reference to a terminology or ontology or may be provided by text. |
Control | 0..1 This element is affected by the following invariants: ele-1 |
Type | CodeableConcept(CodeableConcept) |
[x] Note | See Choice of Data Types for further information about how to use [x] |
Comments | Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
