0. Quantity
Définition | The comparator is not used on a SimpleQuantity. The unit SHALL be a UCUM code. A measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies.
Court | A fixed quantity (no comparator) with UCUM unitA measured or measurable amount
Commentaires | The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use explicitely excludes the use of the simpleQuantity "comparator" element. The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.
Contrôle | 0..* Cet élément est affecté par les invariants suivants : ele-1
Est modificateur | false
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) qty-3: If a code for the unit is present, the system SHALL also be present (`code.empty() or system.exists()`) sqty-1: The comparator is not used on a SimpleQuantity (`comparator.empty()`) qty-3: If a code for the unit is present, the system SHALL also be present (code.empty() or system.exists())
2. Quantity.comparator
Définition | Not allowed to be used in this context How the value should be understood and represented - whether the actual value is greater or less than the stated value due to measurement issues; e.g. if the comparator is "<" , then the real value is < stated value.
Court | < | <= | >= | > - how to understand the value
Contrôle | 0..01
Binding | Les codes DOIVENT (SHALL) être pris de QuantityComparator http://hl7.org/fhir/ValueSet/quantity-comparator|4.0.1 (required to `http://hl7.org/fhir/ValueSet/quantity-comparator|4.0.1` ) How the Quantity should be understood and represented.
Type | code
Est modificateur | true parce que This is labeled as "Is Modifier" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value
Valeur primitive | Cet élément primitif peut être présent, absent ou remplacé par une extension
Résumé | true
Exigences | Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology.
Signification si manquant | If there is no comparator, then there is no modification of the value
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. Quantity.system
Définition | UCUM requiered for the identification of the system that provides the coded form of the unit. The identification of the system that provides the coded form of the unit.
Court | System that defines coded unit form
Contrôle | 10..1 Cet élément est affecté par les invariants suivants : qty-3

Exigences | UCUM requiered. Need to know the system that defines the coded form of the unit.
Valeur fixe | `http://unitsofmeasure.org`
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
6. Quantity.code
Définition | A computer processable form of the unit in some unit representation system.
Court | Coded form of the unit
Commentaires | UCUM code required. The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system.
Contrôle | 10..1
Type | code
Est modificateur | false
Valeur primitive | Cet élément primitif peut être présent, absent ou remplacé par une extension
Doit être pris en charge (Must Support) | true
Résumé | true
Exigences | Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))

0. Quantity
Définition | The comparator is not used on a SimpleQuantity. The unit SHALL be a UCUM code.
Court | A fixed quantity (no comparator) with UCUM unit
Commentaires | The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use explicitely excludes the use of the simpleQuantity "comparator" element.

2. Quantity.id
Définition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Court | Unique id for inter-element referencing
Contrôle | 0..1
Type | string
Est modificateur | false
Format XML | Dans le format XML, cette propriété est représentée comme attribut.
Résumé | false
4. Quantity.extension
Définition | 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.
Court | Additional content defined by implementations
Commentaires | 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.
Contrôle | 0..*

6. Quantity.value
Définition | The value of the measured amount. The value includes an implicit precision in the presentation of the value.
