0. IVL_PQ
Control1..*
Logical ContainerClinicalDocument (CDA Class)
binding styleThis type can be bound to a value set using the CDA binding style
XML FormatIn the XML format, this property has the namespace urn:hl7-org:v3.
Invariantsivl-pq-center: Center cannot co-exist with low or high (center.empty() or (low.empty() and high.empty()))
2. IVL_PQ.operator
Definition

A code specifying whether the set component is included (union) or excluded (set-difference) from the set, or other set operations with the current set component and the set as constructed from the representation stream up to the current point.

Control0..1
BindingThe codes SHALL be taken from CDASetOperator
(required to http://hl7.org/cda/stds/core/ValueSet/CDASetOperator)
Typecode(cs: Coded Simple Value)
Primitive ValueThis primitive element may be present, or absent, or replaced by an extension
XML FormatIn the XML format, this property is represented as an attribute.
Default ValueI
4. IVL_PQ.low
Definition

This is the low limit of the interval.

Control0..1
Typehttp://hl7.org/cda/stds/core/StructureDefinition/IVXB-PQ
LabelLow Boundary
6. IVL_PQ.center
Definition

The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.

Control0..1
Typehttp://hl7.org/cda/stds/core/StructureDefinition/PQ
LabelCentral Value
8. IVL_PQ.width
Definition

The difference between high and low boundary. The purpose of distinguishing a width property is to handle all cases of incomplete information symmetrically. In any interval representation only two of the three properties high, low, and width need to be stated and the third can be derived.

Control0..1

10. IVL_PQ.high
Definition

This is the high limit of the interval.
